My car is doing this and I bought a coolant conrtol valve. According to my stealership that what they reccommend the part is bout $300 unless you can get the hookup. I got mine for about $160. There is another thread on this with the valve part#s and labor costs

so what is the exact problem.

is there a drastic difference in tempeture between the left and right vents? Or does the ac get cold then all of a sudden blow warm, then back to cold, then warm.

drastic left to right temp differences (more than 10 degrees) you would be looking at the dual coolant control valve.

the cold then hot, cold then hot, i would be looking a bad Evaporator discharge temp sensor.

there are service bulletins on both, with how to check them.

This is my problem.

is this gonnna be expensive to fix?

I paid for an extended warranty, this should be covered right? while i am in there to fix this....should i have em check something else why they are at it. might as well cuz i gotta pay 100 dollar deductible.

 

[fordtechguru]

there is a tsb for that if you are talking about dual zone a/c problems -yes it's pricey and yes it's not fun to change, under hood ,behind motor,etc...lol

 

[LincolnTech38]

wich extended warranty do you have? It should be covered.
