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.
View 13 RepliesI 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.
View 1 RepliesI've read that this is a somewhat common problem but can't find the part number to what I need. My heat stopped working and won't change blowing any temp only blows slightly chilled air. I found that its suppose to be a part in the dash that controls this thru the climatronic head unit some lever that isn't getting pushed over correctly dew to a worn out part. What part I need to get my heat back working.
View 4 Replies99 f250 4x4 7.3 superduty has no heat. A/c seems to work ok had similar problem last year and replaced heat control switch in dash. Same thing this year, a/c works fine but no heat when turned to red or heat setting. Blower works fine just blows cold air. What may be sticking? Getting cold in MD and (excuse me but) Johnson goes full turtle on my morning ride to work.
View 5 RepliesJust 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 RepliesI'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?
View 3 RepliesOn 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 ....
My daughter has complained about periods of no heat- fan blows but cold air. Next time the heater works fine. She is keeping coolant level up but does need to add a bit (pint or so) say every other month. Last week during the Chicago snow storm she called and told me the heater (which had been working) blew a bunch of "smoke" into the car and onto the windshield and windows which then froze solid. I assume the smoke meant steam and she did say it had a sweet smell when I asked her.
Car was towed to a SAAB dealer who ran the car for a couple hours and found no issue and then drove the car for a period with no issue. I had my local mechanic also check it in the past for no heat and it also worked fine then. Only thing I can think of is that there might be a small/intermittent leak in the head gasket with an exhaust bubble forced into the cooling system? That does not explain the steam in the passenger compartment though. Could it?
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?
View 10 RepliesHeat 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.

View 4 RepliesMy 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?
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 ...
View 2 RepliesBought new oct.2012. Fiirst time used heat blows cold from one side hot from other. not consistent, will vary from left cold, then hot from right or the opposite. been fighting with chrysler from then till now. engineers know problem exists and are working on a fix. haven't found it yet. contacted chrysler numerous times, just get passed from one to another.
View 2 RepliesI have a 2002 Ford Ranger 3.0L truck that, all of a sudden, has a problem with the HVAC system that blows air only thru the defrost vents even when selecting any other vent levels (defrost, face/middle or floor levels).
I did find a thread on another forum regarding this problem, only it was for the 95-01 Ranger model years, yet they say that the 2002 Ranger is not the same as those earlier models.
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.
View 9 Replies2006 F150 King Ranch. My Air Conditioning no longer blows cold air. Additionally, the Temp Guage is pegged dead left. No movement at all even at normal operating temp. I've had the dealer replace 2 sensors and a wiring asy (XL3Z-14A411-AA). I still have the same problem. No cold air and the gauge is still pegged dead left.
View 3 RepliesMy 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 ...
View 1 Replies02 6.8 4x4 excursion. When I start the truck cold, the trans temp gauge immediately moves to "running" temp. Not really sure how this happens, I'd figure that if the xducer was trash it would ride all the way high or all the way low. What's happening here? I'd sure like a functional gauge...

I have not heat from the vents, doesn't get warm at all. If I idle the enginer in 30 Degree weather it gets to almost the C.
Upper Radiator hose is hot, I have verified the thermostat is new and it opens at 192 degrees as it should. Replaced the Water Pump, Fan spins freely.
I have attempted to burp the system, it isn't kicking out anymore air from the lines that I can tell. I used a large funnel and filled it with Anti-freeze, it filled the radiator, burped the system and the reservoir filled to overflowing. All with the engine hot. (To be specific the funnel was always full of fluid so no air could get sucked backwards)
The heater core hose on the left when looking from the front of the vehicle does not get hot, the one on the right gets warm. I theorize that the heater core is clogged up somehow and that is why that left line doesn't get hot. There is no fluid in the cab of the truck from the core.
I have a 95 ford f350 when u run it with the heat on the truck temp gauge says its overheating the heat will go from nice and hot to ice cold as soon as the temp gauge goes up to the red. I replaced the thermostat also checked for coolant leak cant find any but truck has strong anti freeze smell and the radiator keeps going low on coolant.
