Why my Passat will not put out any heat when idling? I recently had some body work done (right front fender replaced) and it seems like this has started to happen...any possibility they didn't hook up some line...???
View 12 RepliesThe heat works fine when driving but when car is idling there is no heat, the blower is working just blowing cold air, the temp gauge reads normal???

View 2 Replies2007 Montana SV6 3.9. I have lots of heat when vehicle is reving 1500 -2000rpm. when idling at 700 little or no heat. recent flush, thermostat, and serpentine belt. I'm thinking, if it was the water pump not circulating enough water the car should be over heating. heat guage remains on the half mark.
View 4 RepliesI have a 2000 chevy venture with 100,000 miles on it and I just had the thermostat replaced a month ago. Now that the weather is getting warmer I have noticed the gauge going up when idling for a few minutes, drive through, etc. Is there a sensor that could have went bad when the thermostat went out that should be replaced? When I start driving again the gauge comes back down. I have noticed that the fans arent kicking on, but when I turn the a/c or heat on then they do.
View 14 RepliesWith the cold weather arriving I've recently noticed that when I have the heater on it does fine while I'm going down the road. However when I idle at an intersection the blower still works but the heat drops off.

View 1 Replies2007 f150 5.4 supercrew, average temp for the last 2 weeks was -27. I plug the truck in all night it starts good and idles down fast engine is warm. no heat after idling for 3-5 min and then try to drive it takes another 5 min for the temp gauge to hit full temp 192. then my windows fog over even the dash and there is minimal heat coming out takes another 10-15 min to clear the windows. what the "F". fulid levels up, winter front on, block heater works, not using or smelling antifreeze, brush off every last speck of snow and I still have to pull over on the highway and wait......should have kept my 95 5.8l.
View 10 RepliesI have an F-250 Ford, 2006, 6.0 turbo-diesel. Started noticing that my heat only works while running at 70 mph or more and the turbo is at around 15-20 psi. Now that it has gotten cold it is definitely an issue. Truck does not overheat, I am not able to feel heat on the hose after control vlave and I do not feel any vacuum on the line (grey) to the control valve. I have checked for leaks, changed out the fill cap, checked anti-freeze level, pulled control valve just to verify its position when opened (which it seems to stay open). It's getting really cold in the cab of that truck now.

Problem: Sporadic heat this winter and sporadic a/c in last summer. (Freezing to death)
I've taken it to two mechanics and they both stated that it is a electrical issue and the a/c clutch was check and it was good. It does have code 22. Where the A/C relays and the Heater relays are?
The heat in 2001 saturn seems to take about 5 10 minutes to come on. Once it does it works fine. Is this a fuse problem?
View 6 RepliesI have a 2001dodge caravan that I can't seem to get the engine temp up on. I've replaced the thermostat and the coolant temp sensor and topped off the coolant. It raised the heat to the first line but once the vehicle is being driven the temp drops to 0 and heater blows cold. During the summer the vehicle runs at normal temp. Have disconnected the ambient temp sensor which did nothing to better or worsen the problem.

Problem: Not heat will come out unless
1) I don't turn on the Fan Motor at all. Very Nice heat will "bleed" out of the vents as long as there is no Fan on - on any setting.
2) Lukewarm heat will come out if I am giving the car gas or revving it. As soon as it goes back to idle or I am no longer giving gas it goes back to no heat at all.
Things I have tried:
Topped up the radiator and tank (radiator has been replaced)
Water pump replaced
No leaks
Thermostat is opening ( Upper hose gets hot, Lower hose stays cold for a while and then gets hot)
Flushed heater core with a garden hose.
Inlet hose to heater core is hotter than outlet hose but outlet hose is not cold to the touch.
Radiator cap has been replaced
Car does not run hot at all
I own 01 Prius with 223K miles, No heat or AC working. Only get outside air. Here is the code I am getting: 3, 3, 4, 1, 4, 2, 4, 3.
View 19 RepliesI have a 2002 Prius that isn't blowing any heat. During the winter it wasn't blowing cold air so I put some freon in it and it leaked out I guess. So I added another can or two and the a/c stayed cold longer.
View 16 RepliesI have to admit this is for my 2001 Civic EX. She warms up easily in summer and winter, never overheats, has a new thermostat and flushed radiator and gives plenty of heat when driving....but as soon as you stop at a light or sign no heat...drive off and you have heat. I was thinking clogged radiator or heater core...hoping it's the former.
View 14 RepliesI have a '06 2.0T Auto, and the first cold day since I purchased the car was a week ago (I live in North FL) and turned on the heat, to find out that little to no heat was getting let out, so I brought it to my local guy, and said that the thermostat was probably stuck open, so he replaced the thermostat and housing for a couple hoses , and tested out the heat just now (55 degrees out), have it on 80 degrees and full blast, and still nothing. Also, usually I hear the cooling fan kick on after I shut off the car for about 5-10 secs, but haven't heard it since its not 90+ out. Its in the 70s.
View 6 RepliesMy neighbors brother has a 2000 Passat v6 4 motion. (Climatronic) Here's the issue... the car has NO HEAT!!! and its cold out side. Last night we tore the lower dash part down to see the air box, when you adjust from hot to cold the servo is moving but were not getting any heat at all. The hoses going into the heater care are hot... there are no leaks.... also tried changing the climatronic unit itself and got no where.... I have a 3 hr drive home later this afternoon.
