its a 92 but checking part #'s it appears to have 91 ACdelco factory a/c..has a 2 wire blower motor..only works on hi..checked resistor..looked ok, but tried new one..no luck..checked voltage to motor on all switch positions..was 11.88-11.91 on all positions..off was off..tried running a seperate ground to battery, but again only worked on hi even thogh other switched positions showed same voltage to motor..its a conversion van w/rear fan that works fine
