93 Bronco A/C

I have a 93 Bronco the a/c does not work neither do any of the positions on the control knob except defrost and off. No floor or vent heating . Any ideas?

sounds like your temp switch gone bad..

try turning off your a/c switch..then have someone look at your a/c compressor when you switch it back on..you should see the "clutch" engage. ( you cant miss it if your looking at it )

maybee your relay as well..still sounds like the dash switch..
