Had to replace the A/C & Heater Fan Speed Switch on my 92 s10 Blazer. When I pulled the control unit out of the dash to replace the switch, the brown "hot" wire pulled out of the black plastic connector. I pushed it back in when I replaced the unit, but evidently it didn't make a good tight connection on the switch terminal. As a result it arched and melted the plastic connector. I've had all sorts of problems since this happened. My question is does anyone know where I can find one of these plastic connectors with the 4 wires attached since I'm going to have to splice it in - other than a wrecking yard ?
