Ford F-150 - 1997-2003 :: Blower Fan Speed Doesn't Increase On Level 3
I recently got a 2002 f150 5.4. The fan speed works on 1 & 2, and 4. It does blow on level 3, but it seems to blow at the same cfm as level 2. I'm thinking this can't be right. But, if it was a simple resistor issue, it wouldn't run at all on level 3, right? So, where I should look first.
View 10 RepliesPrius (2004-09) :: 2006 - A/C Blower Speed Slows Down When Set To High After Running For A While?
I have a 2006 Prius and lately, the fan will stop blowing hard on long drives on hot days when the fan is set to High. This happened on a 3 hour trip on the interstate and again when I was driving some back road for about 2 hours. The first time, I noticed the cabin temp was getting hotter so I went to switch the fan speed higher and noticed it was already on high. It was not set to Auto.
When I got home, I let the car cool down for about 30 minutes and when I turned on the car, the AC was blowing full speed and was getting cold like normal. When the fan speed slowed down on its own on the interstate, it was probably blowing at a speed similar to what the fan would normally blow if set to the middle position or maybe even below that. Why the fan would slow down on its own when set on high.
I also just checked the temperature coming from the vent after running the AC on LO temp for about 10 minutes. It was reading 50 degrees with a digital meat thermometer and 46 degrees with an infrared thermometer. So, when the car is cool, the AC seems to be working fine. Just wondering about the fan speed and the fact that the car gets really warm when it slows down on its own.
Prius (Gen 2) :: 2005 - Changed Evaporator And Now Blower Motor Doesn't Work
So the evaporator in my dads Prius had been leaking for a while so we finally decided to bite the bullet and change it. Everything came apart fine. Changed the evap and expansion valve. Put it pretty much back together except for glove box and a pillar trim pieces. Push power button twice to make sure all the flaps and blower motor works as it should. Well the blower motor doesn't come on. I hear the relay click when you turn the fan on in the mid. No power at the fan though. I checked just to be sure. I've looked all over for loose wires/plugs but have yet to find anything. I started the car up and everything works fine except the blower motor. What it could be?
View 13 RepliesPrius (2010-12) Fuel :: Pulse And Glide At Constant Speed?
Two weeks ago we were driving across rolling hills in southern Ohio. I started to wonder, "What would be the perfect road for the Gen 3 Prius?" Is there a road shape that would allow the benefits of pulse and glide without the speeding up and slowing down?
Let's assume no net elevation change on an interstate highway and a driving speed of 60 or 65 mph. To stay in the most fuel efficient engine ranges for the ICE, we'd want down-hill stretches where the power demand shown on the hsi would be in the bottom 1/4 of the total Echo range, and up-hill stretches where we could stay in the top 1/4 of the hsi Echo range (just below Power).
Would the optimal ascent and descent angles be the same, or would the angle of decline be shallower that the assent angle? Would mileage (mpg) be better on this ideal up and down road than mileage on a flat road at constant speed?
Lexus GX 2004-09 :: Slight Hesitation / Surge While Driving At Constant Speed?
my 2006 GX has 95000 miles and recently i've noticed a slight hesitation followed by a slight surge in speed while driving at a constant speed. it almost feels like i'm pushing the accelerator then releasing it. its a very mild difference but i'm guessing tranny and have 5k left on my warranty. it occurs at a variety of different speeds but most noticeable at about 35-40mph and up around 55mph.

Whether in heat or AC mode and any dial position, I'm not getting nearly enough air blowing out of the vents to cool or heat the cabin in a timely manner. The fan switch is working in all positions but I have to use high speed all the time to get enough air to defrost the windshield. I've also noticed that when defrost is selected, air only comes out on the inside part of the vents, not the outside. Is there a cabin filter on this truck, I've checked auto parts stores and they don't list anything for it.

I have a 2010 with about 166k miles. I am getting a slight hesitation at slight acceleration or constant speed. It does not matter if it's on highway or freeway speeds. Now I am not sure if this in junction with me changing the PCV valve, cleaning the EGR pipe, or cleaning the TB for carbon recently. It started happening a week after it though.

View 2 RepliesPrius (2004-09) :: Constant Variable Humming Noticeable When Driving Over 40 Mph
I was sure it was a wheel bearing I'm at 198k miles. I replaced all the wheel bearings in the car and the noise still persists. The old bearings were definitely in need of replacement so I'm fine with that.
Neighbor mentioned my rotors looked warped and they may be vibrating the calipers but the they don't seem to vibrate harder under heavy braking. There's no vibration through the steering wheel.
When I did the front bearings the CV boots are still holding up. I kinda busted some of the dry and cracking boots around the tie rods and ball joints but that's for another day.
Anyways, I run winter tires all year round being in snow belt and they are cheaper. Wear is worse on the front tires outside edges from cornering and I'm gonna replace and go for an alignment soon.
It has to be something that is spinning on the car from the noise I'm getting. Worse at higher speeds, constant variable humming.
Prius (2004-09) :: 2008 - Constant Whirring Sound When Engine Is Running
My 2008 Prius has started making a noticeable soft whirring sound whenever the engine is running. You can hear it both inside and outside of the car. The sound lasts exactly 30 seconds, then pauses for 4 seconds, than repeats . When the car is turned off, the sound can be heard for about another 10 minutes before it shuts off entirely.

I started my 05 prius this morning, and it starts up and is running in normal time. But there's a constant long beep tone that doesn't shut off and after it starts it shoves the break pedal back out while my foot is still trying to keep it depressed. There's a brake light that is on after, but no error icon on the display. I didn't try driving it to see if it lets me, because of something possibly wrong with the brakes. What might cause this?

Sometimes (but not always!) when I turn my Prius (2008) off and open the driver door, there is a constant beep. There are no interior lights left on. I think whatever I am doing wrong might be draining the 12v battery as it keeps going flat.
View 4 Replies7 Series :: Tranny Will Downshift Then Up Around Constant Speed Of 40-45
I have a 91 735i, 4sp auto, 3.5lt. Usually around constant speed of 40-45 the tranny will downshift then up then downshift an sometimes it will downshift to 2nd which scares me thinking it might downshift to 1st an explode the engine or tranny. If I engage cruise control it does not downshift. This does not happen all the time but when it does it can be very severe with jerking and slamming into an out of gear. The trans has a dipstick and the fluid does not look bad. I replaced head gasket and it was doing great for about a month and then poof the downshifting started.

I have a 2005 Dodge Caravan with a heater blower that doesn't seem to be working. Whether the heater knob is on low or high, it does nothing, but you can feel a little heat coming out, though. I was told it may be a resistor behind the glove box. I've already checked the fuse, and it seems OK. What do I do?

View 3 RepliesS-10 :: 4.3L Engine Misfires Or Hesitates At Constant Speed On Highway
My fathers truck starts, runs, idles fine but once on the highway at constant speed, the engine misfires or hesitates causing a small buck or jerk but continues on down the road. The SES light is on. He took it to O'Reilly and they put some kind of computer on it and (I think) it said misfire in a cylinder. He replaced one of four O2 sensors, pickup in the distributor (not sure what this is called), wires, and plugs with no cure. This problem is very strange as again, it only does it a constant speed; truck runs fine at idle, acceleration, deceleration, startup, etc. There may be a slight sulfur smell during idle and there is a decrease in gas mileage.

This truck has 180km on it and runs fine except as of lately i have developed a surge while at constant speed. When i step on the gas it does not seem to happen.....it only happens when I reach a constant speed. The odd time it will surge at idle and the engine will rev up and down on its own also. When at highway speed it seems to not do this. The truck never dies completely....just surges slightly.

I have a 1991 celica gt 5sfe hatchback. I am getting a surging at constant speed, at idle it's fine as well as acceleration. It only does it when trying to maintain a constant speed in the range of 10-50 mph or so. It's feels like I'm pushing the gas and letting off repeatedly. I took it to get an emissions test and it failed on the low side test with high co2 reading, everything else is fine and one place couldn't do the test because the surging kept kicking the computer out since they have to keep it at a constant 15 mph speed. I think whatever is causing the surging is causing me to fail the low side emissions. Could it be the iecu?
