Hi-
My 1991 Toyota Previa's A/C just stopped working. I was told that it is a temperature control switch that is located deep in the dash. Is this true? I just had the expansion valves, blower fan and compressor replaced. Now the blower fan stopped working I was told that it is a temperature control switch that is recessed deep in the dash. For some reason I think the mechanic lied to my wife. Could someone tell me if this switch exists?
