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?
View 7 RepliesI'm having issues with my 09 Camry. Yesterday my water pump shoot craps on me. SO this morning I replaced the water pump. After replacing the water pump I noticed that the heat would work only when the car is moving. So I went to the store again and bought a thermostat. Replaced that and the heat still only work when the car is in motion. So I checked the radiator cap it was bad I was able to hold it in my hand and spend it with the other hand. Ok replaced the radiator cap. I let the car sit at idle running and the heat worked shortly then it started to blow cool again. I checked the radiator hoses and the lower hose was cold right along with the thermostat housing.

View 1 RepliesHave no heat, the a/c works fine, ran the diag. and got codes 1262,1265,1947, and 5041, I don't even know where to begin.
View 10 RepliesSo after replacing the entire clutch assembly, coil packs, plugs,valve cover gasket, thermostat housing, blah blah blah basically a tons of new parts. I get her up and running and notice my heat only works when under throttle...yup water pump...but wait what's that milky substance under the valve cover cap now never ran hot but appears to have blown the head gasket as well. Doing compression test this weekend..
View 9 RepliesI 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.
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?
View 1 RepliesI recently moved from TX to MN and it's getting cold enough to need heat in my car. Well I've turned it on and nothing but cold air comes out. I've check my coolant level and it was getting close to low, so I added more and I've checked the fuses and they look good. So, what it could be or how i can fix it?
View 14 Replies5.4 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.???
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 RepliesSo, 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.
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?
Having issue with heat only working when the temp is at 90? I turn it down one click 85 and it goes cold?
View 3 RepliesMy 03 Camry is blowing cold air on the passenger side while the heat is on. The drivers side blows hot air as it should. The coolant is full. Its a 4cyl LE and does not have dual climate control.
View 14 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.
View 4 RepliesI 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.
View 2 RepliesOn my 14.5 there is something wrong with the Entune. Every time I try to use voice commands it tells me it is initializing and to please wait. No beep or voice, just a message on the screen. I first thought it was because I had an iPod Classic and it was taking too long to index, but it does that for everything; phone, nav, even voice training. I also notice it often plays a completely different track then the one I select when manually selecting songs on my playlists, it that normal?
I tried cycling the unit on and off, and made sure everything was up to date. Should I try resetting everything on the unit back to factory? I don't think that will default the firmware though, will it? I have a service appointment on the 30th as a 30 day checkup since buying it but would like to try and figure it out first. I've seen some posts suggesting that Toyota has been replacing head units for it, which would suck.
I am trying to understand how the air circulation, fan system works in the 2012 Camry Hybrid XLE. These days I have fan turned off (the temperature or fan speed does not display). Only the mode is displayed (towards face). However when I drive, sometimes I feel slight cool air coming from the air vents. This is very noticeable when I drive in cold weather as I get rather hot air coming out from the vents. How does this happen? Is this normal?
Now I understand that when I do turn on the fan, the air speed venting out increases and the temperature is what seems to be ambient on the outside of the car (no AC).
My AC is not working on any setting but defrost. Warm air blows out on the reg AC settings, but if I turn it to defrost, chilly air comes out.
View 2 RepliesIn the past month, I had to use my "cruise control" a few times, and I had the bad experience that sometimes it works as it is intended to do, but other times I am unable set it after I turn on the cruise control; thus, it works on and off.
