Ac cycles to heat-this is when the ac is needed-hot air comes out of left center vent and cool air comes out of right center vent simultaneously. Eventually all vents blow hot air. Was told several causes are...calibration (which I had done 2x-did not fix issue) Heater core was another cause (was advised $2,200 to fix) Flapper control...whatever that is, was another cause that was told to me. Do you know what the real cause is?
It wouldn't be the heater core. The flapper control, is the blend door actuator, which should close off to the heater core so hot air doesn't get in with the cold air from the evaporator. Most likely it's the actuator, not opening and closing the doo ... 2003 Lincoln LS

Car is running hot when i stop, but then cools off when i start moving, I brought it into the shop and was told i have oil leaking into the coolant, which was then told that it could go the other way and be real bad, He told me I need radiator flush, new thermostat and need new intake gaskets. Was told it needed fixed within 5 to 6 months or the whole engine would blow soon. Told me it be around 750.00 for everything. Does this all sound right? Its a chevy venture 2001 and I just got it please h
For the most part it sounds half way accurate. First of all telling you that it needs to be fixed within 5 to 6 months, in my opinion was a scare tactic used to try to get you to approve the work. Because no one can say it will last th ... 2001 Chevrolet Venture

God, that is expensive, worst than here in the Uk!!! This would cost 1/5 of the price here if you go to a side garage...Anyway, the garage is right, overheating can cause head gasket damage and trust me, you won't be able to even sell the car after t ... 2003 Chevrolet Monte Carlo
Check engine light was on and car running hot when idling and sometimes while driving. Had fuse replaced did not fix problem, then had fan assembly replaced. Check engine light came on again, running hot while idling. When car heats up right fan goes off but will come back on when turn A/C on but A/C not cool when idling. I have two mechanics telling me fan assembly needs replacing again (its just been 3-4 months) and another shop telling me its a computer/circuit problem. What do I do, I really
If the fan goes on with the a/c then the fans relay is bad ... 2003 Chevrolet Impala
Horn and power seats quit working. maxi-fuse extremely hot. pulled it out and re-inserted after it cooled down. fixed the problem temporarily (a day or so). swapped that maxi-fuse with the one above it (power windows). worked for a couple weeks. now the seats and horn don't work again. seems like the fuse port for the horn and power seats is bad. does the whole fuse assembly need to be replaced?

I think you answered your own question.. torque converter clutch or overdrive solenoid. also your overdrive band could be a little worn and about ready to **** the bed for good but i'd check the other things. if you had transmission work done on it b ... 2001 Dodge Durango

Our 2006 T&C was serviced last fall under warranty. The dealership kept it 4 days hunting for AC leak, etc. They were unable to find anything wrong, recharged the system and sent us home. Now it's summer and even in coastal Maine we need the AC working. It is blowing hot air, not even trying to cool. Of course the 90 day warranty is up. Is there an easy/cheap fix?

How do I change the cooling fans to kick on sooner than they do? I live in the desert and its very hot! I put in a new thermostat which is better suited for my climate...but how do I get the fans to kick on sooner? Need a cheap fix please.
The only fix I have found besides adding a switch to the common terminal of the fan relay, and a ground, is to pick up the following ECU programmer from Corvette Central: ... 2004 Chevrolet Corvette
2001 Chevy Lumina. Got hot, pulled over. Reservoir was boiling over but radiator cap was cool to the touch. Let it cool off. Check water in radiator and reservoir, needed very little. Started driving and almost immediately got hot again. Reservoir boiling over again. Let cool and when released pressure with radiator cap all water sucked out of reservoir. Some times runs fine and some times gauge goes to hot. And sometimes it goes to center and back down several times.
Sounds like your thermostat is sticking closed at times, not allowing coolant to circulate through the radiator for proper cooling. Replace thermostat. ... 2001 Chevrolet Lumina
I seem to have several problems, I bought the Santa Fe from a car lot, the car's a/c needed charged on the test drive, they promised it would be fixed before we buy it, well 2 weeks-more freon-2 weeks more freon and lines were cracked, needed new hoses, 2 weeks-hot again, now it is the evaporator needed replaced, 3 weeks-hot again, freon spit out of vents, now they replaced the compresser and charged me half of part and work. BUT, It still is hot, I know it's Florida, but I see a lot of these Sa

A local garage mechanic says the clutch has stopped working on ac that is why it blows hot air instead of cool says it will cost $900. to fix cause I have to buy the whole ac unit does this sound correct? when it is cool outside it does blow some cool air but once the day gets hot it gives nothing but hot air
Have you tried charging the ac system? most ac compressors have a pressure switch that will not allow the relay to engage the clutch if the coolant pressure is low. $15 can of r134a and maybe a $20 Haynes manual is well worth the price difference, ... 2004 Kia Sedona
What could cause my 2002 BMW 330i to continue to run hot after replacing the cooling system, bleeding the system of air and chekcing for a head gasket problem. They said they car was fixed it drove great then got hot after 13 miles and cools down very quickly. I started the engine after it ran hot and it sit dead center for about 5 minutes before it started to climb again.
Check to see if the engine is truly hot. next time with the motor running find the upper radiater hose and gently place your hand on it. if its cool or just warm to the touch your heat senser is probable the problem. if its hot and hard like its unde ... 2004 BMW 3 Series
2001 Lincoln LS. A/C problems. My a/c problem are similar to other i have read. My A/c will cool very nicely for 10 miles - 15 miles.... then it start to blow very hot air on the right side. Sometimes if I accerate rapidly, it will begin to cool. Then, It will start to cool on the right side and blow hot air on the left side. I took it to the Ford place and they want $1200 to fix the compressor. I stand that the compressor can not be bad and work as well as it does at times. Help please.
I would take it to a shop,not the dealer,have them add 12 oz of freon,see if this does the trick,they will do this if they are a little low.If this does not help,have the shop check for vacuum problems to the ac control head.If this was at all helpfu ... 2005 Lincoln LS
