Air Conditioning problem
1995 Chevy S-10 4 cyl Two Wheel Drive Manual

the defrost is the only function that will work on the heater/ac control no matter what function you put the dial on(max air,normal air,vent etc) would replacing the heating/ac control fix the problem?

Just fixed the same problem on my 95 S10 Blazer; It was a vacuum leak. The climate control is vacuum actuated. I had a leak in the small vacuum line that attaches at the back of the intake manifold (next to distributor). My Blazer has the 4.3 Vortec V6 [Vin W with VCM-A computer]. Hope this helps.
