2002 Thunderbird blows warm and cool air

[cy38104]

Usually I drive with only the two driver vents open. After about 30 - 45 minutes on a trip, the cool air from the vent in the middle of the console becomes warm. If I open the other middle vent on the passenger side, that newly opened vent takes the warm air and the driver's middle vent cools down some but not a lot. It seems that decreasing the desired temp has no effect. Increasing the desired temp has no effect. would love to know what's going on before taking it to the dealer. Thanks in advance!

sounds like your a/c compressor isn't kicking in. possibly needs recharged or one of the switches might be bad

I'm having a similar problem with my 2002 T-Bird, however it seems that it's just the passenger side that suddenly starts blowing hot air for no apparent reason.

The problem goes away when I turn the car off and then restart it, however the problem may or may not re-appear after driving for a little while.

I haven't been able to tie the sudden switch from cold to hot to any particular action on my part. (ie, fiddling with the temp controls) It also doesn't seem to be tied to driving over a large bump in the road.

Since there are separate temp controls on each side of the car, I'm assuming that the passenger side control is connected to the problem, but I have no idea where or how to start looking.

I'd appreciate any help from anyone in the forum.

Thanks,
Ray

Yup, clean your compressor and A/C unit too. Check it too for some possible problems.

check your vacuum lines, listen for air leaks under the dash or out by the firewall.
