1992 Toyota Previa Repair Question
1992 Toyota Previa AC switch problem?
1992 Toyota Previa 4 cyl Two Wheel Drive Automatic 123000 miles
My blower motor was coming on intermittently - then just on med and high. One day smelled a burning electrical smell - ac blower no longer runs -
Now when I turn on blower and depress AC switch nothing happens - not even a green light by the AC button which used to always be thwere when the button was depressed.
When I depress the AC switch the engine can be heard goiong under load - the compressor runs and the rear AC blows cold (separate blower and blower switch for rear)
The front has nothing going on so I bought a switch out of the local upull a part as well as a blower resistor. I checked the blower by jumping it to the battery - front blower runs fine - swapped the blower switch and resistor but got no result - still no AC
Any clue? Are there other relays or fuses I could replace???
Check 40 amp Circuit Breaker #37 in instrument panel fuse box.
Let me know
Thanks for donate

From the symptoms description of electrical burning smell, I believe it could be due to a burnt control unit.
I have the schematic here and I would suggest checking the 2 amplifiers.
