Ford A/C :: No Heat / Only Cold Air Blows
Just picked up an 87 150 and have found the following few problems. (Chilton no longer has a "troubleshooting" section...taking that POS back). Anyway here we go... No heat. AC blows cold, but there's no heat. Possible problems and fixes?
View 9 RepliesFord A/C :: Heat Blows Cold Air
I'm having with my truck. During a drive cross country my heat started to go from hot to mildly warm to cold in probably 5 hours. After stopping I checked my coolant level and it was empty. I do have a leaky head gasket and have driven about 18 hours so I'm guessing that's where it went. I could not find a leak anywhere. I filled it back up and left the cap off the reservoir to let any air work it's way out. My heat still blows cold as ice but if I shut off the heat completely and wait ten seconds then turn it back on it will blow warm air for maybe two seconds. What this could be?

On occasion the heat on my mk6 golf will start to blow cold when turned to the max click. Turning it back one click will cause it to start to blow hot again.
Friend at the dealer said he thought there was a software update for the hvac controls ....
Ford Excursion :: No Cold Air Blows Only Heat
I have a 00 Ford Excursion and only heat blows out of the front vents, the temp control doesn't work at all! The back has it's own controls and will come out cold (not a/c just the outside air) when the front is on (blasting heat). What this could be?

I have no heat in the LS at no settings. The AC runs good but does not seem to be regulated as it blows cold at any temp setting. The fan responds to settings but i still get no heat even with the AC turned off. I would like to find a diagram that shows the locations of the bleed valves to start a coolant air bleed.

Heat blows warm at best and A/C isn't all that cold. I want to believe its a blend door issue and dive into it this weekend and fix it but there isn't a single piece of foam coming out of any of the vents. Of all the systems on the car, HVAC isn't my cup of tea I don't know anything about it. What else could be the problem? I can live without A/C but the heat things must be fixed.

My g/f's 98 Passat 1.8T has been pretty bad on being able to blow hot air inside, and now that its colder out its even worse.
Ever since she got the car, the coolant temp gauge is always at it's coldest, so I'm thinking its time for a greentop sensor. Her coolant right now is a lil low so, in the meantime, I'll be headed to the dealer to get both a new CTS and some G12.
Her fan does blow air, but could there be anything else wrong that would keep it from blowing hot air?
Ford - Ranger :: 1997 2.3L - Intermittent Heat / Blower Just Blows Cold Air
There used to be a audible pop in my stereo speaker when my heat would kick on. Now there is not. My heat did this last winter around the same time. I checked Fuses. The blower blows, but it just blows cold air. It could be a thermostat, or a clogged heater core. 1997 Ford Ranger 2.3L ...

I have a 2002 Dodge Durango and the rear passenger air blows cold only - was fine last winter. Neither the passenger or the driver controls will get warm air to the rear via the overhead vents. Warm air comes out under the front seats to the rear only.

My brother-in-law has a 97 F-150 with 4.6L that has no heat in the cab (blows cold air no matter what setting at HVAC controller). Heater core was replaced one year ago and T-stat was replaced last night. Coolant level is full and the heater hoses are BOTH hot so I believe warm coolant is flowing through the heater core. I am thinking that the HVAC controller may be at fault or maybe the mixing door in the HVAC plenum is malfunctioning. I have 97 rangers that had a broken hinge pin for the mixing door inside the plenum (a common problem with these trucks), maybe this is the same issue (I don't know). I am taking the whole dash out to see what the trouble is.

My 2009 silverado ltz is haveing heating issues. when you first start truck all work fine. After a couple min the drivers side vents loose heat and blows cold air. the heat on the pass side works fine. then the vent will change to defrost even though the display still shows its on vent. the only way to get it back is to mess with the vent control. then it will last about a min then back to defrost. at this point i just turn it off. I have already replaced the control panel to no avail ...

Heat shield around the rear muffler near tail pipe is a piece of junk. it makes noise because its so flimsy. The wind blows on it going down the road its about as strong as tin foil. If you hear noise from the rear, check both heat shields they may have stones or leaves inside them, they can make weird noises.
View 3 RepliesFord Super Duty (1999-2016) :: 2005 - Heater Blows Cold Air At Idle?
I've got a 2005 F-350 PSD KR. At highway speeds I get heat coming out everywhere it should. In stop-and-go traffic or at idle, the fan just blows cold air. Once back up to speed, hot air starts blowing again.
The fan stays running and the heat position (lower/upper-vents/defrost) stays the same. Just the temperature of the air blowing thru changes.
Things I know it isn't, thermostat is fairly new, anti-freeze is topped off, and the radiator cap is both good and on like it should be.
It sounds like maybe the blend-door or a vacuum leak according to a few of the posts I found with similar symptoms.

I have a SAAB 2000 95, and the heat isn't working. I was told by a local shop that the blend door motor isn't opening to allow the system to switch from air to heat. He said that the heating system was working, but that the hot air can't exit the dash. He said it would have to be repaired at a dealership.
View 3 RepliesBuick - Parkavenue :: AC Vent On Driver Side Blows Cold But On Passenger Side Blows Extremely Hot Air
I have a Buick park avenue 1998, 3.8L V6 engine. the problem is: The ac vent on the driver's side blows cold air but on the passenger side blows EXTREMELY hot air. no matter how cold or hot you set the ac it blows at the same temperature on both sides. Florida heat is setting in and my passengers are melting. I am really hopping that is not something to bad and that I can fix it myself. Tip: this started happening after i had the alternator and the battery replaced.
View 1 RepliesSonata NF (2006-10) :: AC / Heat Blows Only About 60% Force
I am recently getting no AC just warm/hot air. I have yet to pressure check the system but i believe the compressor still turns. But I did notice throughout this the vents are only giving about 60% force on heat and AC as they used to. The blower motor spins although, cleaned the cabin air filter and one pin broke when putting it back. the blower motor spins louder on the "4" setting. I am guessing this is related to no A/C since it happened the same time and i don't think that low refrigerant would cause the heat system to blow less efficiently...
