A/C intermittent 0n 95 EB

[skikt22]

The a/c in my sons 95 works fine when it's on max air. In fact its down right cold. When it is switched to auto however ir runs cool for awhile and then blows hot. The condenser obviously is fine and the sytems charged, but there is either a bad sensor or relay. I've already had to replace several relays (windows and locks) recently so I'll probably just replace the WOT A/C relay as it's just $7 and easy to do but thats shooting in the dark.

Has anyone had this issue and what was the cause.

Have your system checked to see if it needs to be charged, I had a similar problem, but it didn't matter if it was on max or normal. See if your compressor is kicking in and out every few seconds, if so, it needs a charge.
