I'm asking for my friend that bought my old 98 GT.
For some reason, his air conditioner will blow out cold air on the passenger side, and hot air on the drivers side. All the knobs are turned to cold. Max ac has been turned off and on to see if it changes.
It does NOT have digital climate control, Just the old three knobs.
Any idea what's going on? Engine temp and everything stays around normal range. I'm stumped.
