Ford A/C :: 1988 - Front Blower Motor Intermittently Works

My mom has a 1988 350 Econoline van chasis that is a motorhome class C.

The front heater/AC blower motor only works when it wants to. It starts very intermittently and then shuts off then you go down the road a little more and it comes back on, it will do the same thing sitting in the driveway just idling. There is no timing it, it just turns on when it wants to and then back off again.

I checked the fuses and the fuses are fine. The blower motor when hooked up directly to the battery blows fine. When it isnt working of course there is no juice going to the blower motor through the hotwire of the blower motor, I have checked this with my volt meter.

I did replace the switch that turns the blower on in the dahs, and it didnt do the trick.

Camry :: Subtle Clicking Noise - Blower Motor Works Intermittently

So for a few months now, my car has been making a subtle clicking noise whenever I have the ac or heat on, kind of similar to the noise spokes on a bike would make when children put a card in them. The noise increases/decreases in speed as I adjust the ac/heater speed.

Recently though, it's gotten to a point where sometimes, the blower motor would completely stop working. I can still feel heat and cold coming through the vents when I turn the AC on, but the it doesn't always blow air. I've noticed that sometimes when I hit a bump in the road, it starts working again. It works at all settings and all temperatures perfectly (when it's working that is).

How should I proceed? I don't know much about cars, but from what I've seen on the internet, it doesn't seem too difficult to replace the blower motor. I just want to be sure that the blower motor is indeed the cause, because I don't want to install a new one to be disappointed when I turn it on and still have the same issue. And winter is just around the corner so I would love to get this taken care of.

Ford F-150 (2004-2008) :: 2006 - Electrical Malfunction - Back Light Works Intermittently - Blower Fan Stop Blowing?

My 2006 F150 was purchased by me in early 2009 with about 28,000 miles on it. It's an XLT crew cab 4X4 with the 5.4. Stock except for a leveling kit and an aftermarket head unit. It currently has about 59,000 miles and has been babied since I purchased it. About 3 years ago I started noting some issues:

A. Oil pressure dummy gauge is all over the place. Some times it will show no oil pressure. Other times it is all the way to the highest mark. Other times the needle has gone 180 degrees past where normal is and is actualy pointing straight down towards the floor.

B. Recently my alternator dummy gauge has started doing the same thing as my oil pressure gauge.

C. The backlight behind my odometer works intermittently, but mostly not at all.

D. My dome light will flicker when first turned on. It doesn't matter which door is opened or if the override switch it turned on. It takes several seconds to come on and will flicker like there is a poor connection somewhere, but stays on once its on.

E. Blower fan will occasionally stop blowing. Once the climate control switch is turned to off, then back to on it resumes working. This doesn't happen often, but does occasionally.

Fortunately, the truck has not left me stranded and I want to keep it that way. We are getting ready to sale my wife's Toyota and this will become her daily driver. I want to take care of any issues before she starts driving it. Are these all separate issues or is there one common issue which could be causing them all?

Sonata NF (2006-10) :: Blower Motor Vibration (heater On High)

Went to have an oil change....service rep came in with my cabin air filter and said it needed to be replaced, I told him "later" as they charge too much for a simple filter.

Two days later I had the need to run my blower on high and it vibrated rather loudly.. I tried different positions on the vent switch but nothing worked.. then it came to mind the Jiffy lube incident. I went in and pulled the cabin air filter out and saw nothing wrong there. Upon further inspection I found a piece of an acorn in the blower wheel.

Moral of this story...if you changes cabin air filter, be sure to check for any debris that may fall off the old filter into the blower wheel when it is removed.

Sonata NF (2006-10) :: Blower Motor Not Working - Switch Is Not Getting Power?

I have a problem with my 09 Sonata. Blower motor does not work at all, on any setting. I thinks it's not getting any power. When I turn the blower on, on the dash, little red light does not come on on the switch. I think the switch itself that controls the speed and power to the blower is not getting any power.

I checked fuses that control the blower and they are fine (I looked up fuse location online).

Sonata NF (2006-10) :: Blower Motor Stopping And Lights Dimming When Braking

My wife has a 2006 Sonata and it ran great up until about a month ago, she started noticing when she hits the brakes and sometimes when she hits the gas the a/c blower motor would stop blowing for a second and all the lights would dim. So i drove the car for a day and she was right. the blower motor shuts off and the lights dim for roughly 1 second during breaking then it all works fine again.

What this could be? the car has no check engine light on or anything. I was hoping this is a common thing with a known fix.

Sonata NF (2006-10) :: Blower Motor Making Noise On Highest A/C Setting

My A/C has been making a loud noise for a couple months now ,only when I put the A/C on the highest setting. I was LONG overdue for a cabin air filter change so I bought a new one and while I was down there I looked inside the blower motor and here's what I saw... It is now blowing fine and not making a noise . Sprayed some Ozium New Car spray on the new cabin air filter and my car is smelling great now !

Passat (B6) :: Blower Motor Malfunction - A/C Only Works On 4

So my AC only works on 4 (no 1, 2, 3). I replaced the resistor as is often the culprit. NOTHING. Still only works on 4. So I unplugged the resistor all together, still only works on 4. So, either my new replacement resistor is also bad (unlikely), or it's the blower motor.

Golf IV / Jetta IV :: Blower Works Intermittently / Strange Odor Coming From Vents

Co-Worker's '03 Jetta TDI

Blower works intermittently. Sometimes all speeds will work. Sometimes only on high. Sometimes on all speeds but at a slower speed than normal. Sometimes it doesn't work on any speed.

Switch doesn't bind, blower motor doesn't make any unusual noises and I don't think it is the blower resistor. He did notice a strange odor coming from the vents the other day and, it appears that the foam on the blend door is starting to disintegrate.

Toyota - Highlander :: Blower Motor Operates Intermittently

I am trying some troubleshooting based on various things I found for my 2010 Toyota Highlander blower motor. The issue is that my blower motor operates intermittently. Here are the symptoms and what I've done so far:

-Sometimes it works and sometimes it doesn't. It seems to be dependent on weather (in the sun for awhile and doesn't seem to like that), although lately it doesn't really seem to matter. Had it in my garage yesterday and it just works some times and not other.

-If it works, all speeds work (full range). That makes me think it doesn't have to do with the resistors, although I can't find the electrical schematics for the car.

-All fuses are fine

-I have jiggled all wires and can never get it to work (if not working at the time) or to not work (if working at the time), so I don't think loose wires are the issue.

-I put a multimeter across the leads going to the motor and always get voltage. When the car is on, it's about 13-14V, and when it's not running just above 12V.

-The rear blower motor works perfectly, 100% of the time

-Light physical agitation of the motor doesn't make it come on or go off

My main question is what is the 3rd lead going to the motor? The two bigger leads are the voltage, but that seems to always be there, even with the car off. I'm guessing the 3rd lead is some control signal for the motor but not sure. I can't ever get a voltage on that lead, but I'm not sure I'm even supposed to. When the motor was supposed to be on and it was working, I unplugged it and checked the voltages, but got the same readings as when it wasn't working.

Honda - Odyssey :: Front Blower Motor Operating Intermittently

Front Blower Motor does not work. 2005 Honda Odyssey, EX-L130,000 miles and I expect at least 170,000 miles more.

History – Over the past four years, the front blower motor has operated intermittently. I noticed that when the weather went through large changes (warm/humid to cold/dry or vice versa), the fbm would not run. The system behaved in the manner described by Honda owners in many of the forums online. After a period of time passed, the blower would function properly again until the next weather change.

About two months ago, the blower stopped working again and it has not returned to form since. The system again displays all the usual symptoms reported on-line. The rear blower works fine.

The controls on the dash seem to be fine (display changes appropriately as I select settings, vents open and close for heat or A/C or which vents I want open). Air flows through the vents selected when I am driving – I have a passive windshield defroster!

Here are the steps that I have taken during the past week:

1.Bought a new transistor/resistor module, OEM Honda Part #79330-SDG-W41 (I checked with a local dealer for the correct part number). I installed it but there is no change in the system.
2.I found information on-line to test the T/R. I checked the old one – Thermal Cut Out is intact and the resistance between posts 3 & 4 (lower pair when installed) is 1,500 ohms. I checked the new transistor and it read out the same.
3.Fuses, relays, power to the blower, blower, ground beyond the transistor are all fine.
4.I reconnected the T/R and fbm and let the fbm lay on the car floor. I started the car with the fan on. Each time I start the car (or turned the ignition ‘On’) the fbm tries to run, but stops in an instant.

The Rat is cornered – it's in the the T/R and the control signal from the control panel to the T/R corner. If I bypass these elements, the fbm goes on and off as I select the fan On/Off from the control panel.

Ford Super Duty (1999-2016) :: Window Washer Works Intermittently Although Motor Is Fine?

So either these trucks have a super small window wash reservoir or there is something wrong with my truck. The window washer works just fine and then stops. The washer motor is still working but nothing coming out. I fill it up to the top again and suddenly it works just fine. The thing is that when I fill it up it only takes between 1 and 2 quarts of water. I'd imagine the recover probably holds close to a gallon so not sure why mine quits working and then is full after 1 to 2 quarts of water is added. Perhaps the pickup tube in mine is bent or something? No light or message on the dash...it just stops.

Sonata I45 (YF - 2011+) :: Squeaky Blower Motor Noise

I have 2011 SE (2.4L) that has a VERY noisy squeak that increases with the climate control's blower speed. The noise stops completely if the fan speed is set to OFF. It has been rectified twice by the dealer, who said they just vacuumed it out or something, that there was leaves/trash somewhere causing this. I don't even park near trees or anything! Anyway, my car is now out of warranty, how can i do this myself?

Sonata I45 (YF - 2011+) :: Steering Wheel Controls On Left Hand Side Intermittently Stop Working

I've got a 2011 Sonata Limited that I just purchased used, 20,000 miles. Everything is great besides the fact that the all the controls on the left hand side of the steering wheel will intermittently stop working. I brought it to Hyundai the first time I noticed and they replaced all the buttons but the issue persisted. So, I just picked it up today from them replacing the entire clockspring and the wiring behind it now. It worked great all day until just as I was pulling into my driveway and it happened again.

They basically told me this would 100% fix it because it's the only other thing that could be the issue. However, my gut keeps telling me it could be an issue with the radio itself. I've read a bunch of stuff on here about the issue but there was only a few responses of fixes (all of which I have tried).
