front air on mini van won't work
I have a 1999 mercury villagener mini van. My front air blows air but warm when on a/c but the middle a/c and the the back a/c both work well blowing nice cool air. My brother-in-law is a cerified mechanic and can't figure it out. he said we might have to hook up to computer to find the promblem but I was wondering if this every happened to anyone or if they know what the promblem.
Thanks for your help!
