We have had bigger issues to deal with lately with intermittent stalling on the interstate. We took car to dealer and we hope they solved the stalling, but for some reason they didn't get around to looking at AC. Sometimes when we have the AC on the vents start blowing warm or hot air instead of cold air. When I cut the unit off for a few minutes and back on most of the time it works again blowing cold air.
Since according to the dealer we have had trouble with our fuel relay I am wondering if this A/C issue might be related to a relay or fuse. Then I start wondering if they might be related.
Also, I read somewhere else something that said if another fan wasn't running that the A/C compressor wouldn't run. Is this correct? I am not sure I have noticed that the fan has been running after the car is turned off.
