Corolla / Matrix 2009-13 :: 2010 Toyota - AC Works Fine When Car Is Moving But When Idle It Gets Warmer
I recently bought a 2010 Toyota Corolla. I have been having some issues with the A/C. The A/C seems to work fine when the car is moving but when it is idle it gets warmer. I have recently gotten the freon checked and they put in some more but that didn't work, same problem still happening. Somebody told me that i need a extra fan which didn't make sense to me. Last resort will be to take it to the dealership to have them check. Once again the A/C blows cold air when the car is going over 50 MPH.

I have a 2003 Camry XLE (4 cyl). The heat will only work when the A/C is on. If A/C is off, air will blow from the vents, but it is not hot. What part needs to be fixed/replaced?

I have a 1992 Mazda 929 in which the heat does not work while the a/c does work perfectly. When the problem first occurred the fusible link for the A/C was broken (indicative of some electrical overload). I replace the fusible link and still no heat.
I went under the passenger side of the dash and changed every visible black box (fuse/sensors)that is attached to the heater core unit. After that the heat still did not work.In relation to this problem the care now runs hot whenever I am a red light or in stop and go traffic.This seems to me a that a mechanical gate from the engine is not opening to allow the hot fluid from the engine to get into the heater core.
Suburban :: 93 No Fan In Front / Back Cold Too - Heat Only When Moving
I have a '93 Suburban, Its actually in great shape, except that the fan made some loud whining noises for about 45 minutes and doesnt work at all now. I have heat, but only when Im driving on the highway and only when the heat is actually turned to the "off" postion on the switch and I dont even have heat when slowly driving around town. The rear fan works, but blows cold too. Im not sure that even gets hot when Im moving, as I feel a cold breeze on my neck when I turn on the fan when Im driving. I dont think the ac works at all...just bought this truck, so havent tried it, and its cold out anyway, so I'll have to wait I suppose.

97 passat vr6. I only get warm air from the vents when I'm accelerating. As soon as I come to a stop it starts blowing cold air. Does this mean there is air in the system? If so how do I bleed it out?

5.4 V8... A/C works for 30min. then stops blowing cold air. Turn system off for 15min. and it will blow cold air again for another 15min. then stops again. Passenger floor area gets cold and can hear fan blowing but no air coming out of vents.
In winter now and stops blowing hot air after 30-40min of driving. Turn system off for 15min. and will blow hot again. Had new A/C compressor and a/c clutch installed back in summer.???
Ford Excursion :: Front Heat Works Occasionally?
My front heat controls work at start up occasionally. The heat will eventually come on in front after 15-30 minutes of the truck running. Needless to say this sucks for defrosting the front window during warm up. The rear controls work fine. I do have a couple that need replacing but the fan control isn't one. Temp & selectors. I've searched but haven't been able to find anything about same issue. Where to start?
View 14 RepliesFord Exhaust :: 2001 F150 4.2L - Moving Heat Shield Right Front Cat Converter
I want to replace the auto trans coolant lines on my 2001 F150 4.2L. I discovered I can actually see the top coolant line flare nut from outside the right wheel well, with the wheel and wheel liner removed. The lower line is just a few inches below. See photo, it's a little off, so the line connector is not seen:
The heat shield is just a little bit in the way for my hands, I have to put one through the red circled area. A 1/2" hex head bolt holds the shield to the frame (circled in green). This was easy to remove from the wheel well. After that the heat shield could be moved slightly away from the points I need to access.
I would prefer to unfasten the shield & move it out of the way for my hands. I found another bolt holding the rear end of the shield down to the frame, wasn't able to remove this - the bolt fastens to a U-nut in the frame that broke off & has trapped the bolt. Are there any other bolts fastening the heat shield down?
I was able to remove the old flare nuts with a 5/8" flare nut wrench, but have not been able to start the new nuts into their fittings, just not quite enough visibility and access.
Passat (B5) :: 2000 1.8T - Blower Fan Runs And AC Works But Heat Is Non-existent
So, for a couple of weeks my g/f's Passat has had no heat. The blower fan runs and the AC works but the heat is non-existent. Fast forward to this morning and now all of a sudden her heat miraculously works again. The car has 170k miles on the clock and had the timing belt and water pump done around 120k miles. The thermostat I'm not too sure about. I don't know when (if ever) the system has had a coolant flush so I plan on doing that this weekend. Is it okay to use something other than the G12 VW originally put in it?
At first I thought maybe her heater core was clogged but if it is I don't understand why the heat would start working again. Any tutorial on how to flush this motor properly and how to access the heater core lines so I can try to clear it? On my car it's a piece of cake but her VW stumps me sometimes.
Prius (2004-09) :: 2005 - Heat Only Works When Engine Not Running
I recently ran very low on coolant with my 2005 Prius and had the overheat light coming on. Immediately before the overheat light came on, I realized that the blower was blowing cold air even though the engine was running. When the light came on, I immediately stopped and refilled coolant at the overflow reservoir and the radiator and let it run through a few times. I have re-topped off the coolant levels and it seems to be holding steady. Hopefully I have not done long-term damage to the engine, but that remains to be seen, and is, of course, very possible given that I let it get so low.
A symptom I have right now is that when I turn the car/engine on, hot air does not come out of the blower. If I remain in park, when the engine turns off, hot air begins to come out. When the engine kicks back in, the hot air stops. What this may be a symptom of?

View 4 RepliesFord Super Duty (1999-2016) :: Heat Only Works At 70 Mph But Not While Idling
I 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.
View 4 RepliesPrizm - Chevrolet :: 1998 - Heat And Cooling System Only Works On The Highest Settings
I have a Chevrolet Prizm 1998 and the heat and cooling system only works on the highest setting which is actually the fan setting. When I have it on any of the other settings such as low or med nothing comes out, it doesn't work. I can hear it click on but nothing comes out. So when I'm driving depending on the weather I have the heat or cold air blasting out of the fan until it gets annoying and I turn it off. I've checked the fuses and they're good. I have not checked the relays because I'm not sure how to do that. I haven't taken it to a shop because I'm poor and don't have a trustworthy mechanic and it works just not on low or med. Should I have this looked at? I don't want to be causing any damage but it seems like it could be something simple.
