My 91 automatic 900s just decided to throw me a challenge. As I parked the car, it smoked and burned up a few wires in the cabin. I was unable to turn the car off with the key and had to pull the fuel pump fuse to stop the car. Before I splice in new wire from a spare harness I want to figure out what was the cause of the meltdown.
I pulled the dashboard apart and found that the "light switch", located at the upper left side of the dash, had a few melted wires. It was the green/white, and the red/green that cooked. Further down the run of wire, I see where the fog light plug wires connect, and all of the wires off of the fog light plug, have melted bare. It seemed to get so hot, it melted the orange plastic plug itself.
From here, as you move towards the main bundle of wire, the wires appear less damaged. I inspected the wires and only find a brown/white wire shows any sign of melting. It passes through a white honey comb shaped plug behind two black relays and travels down the main wire harness. (down past the main air vent)towards the shifting column where the melting stops. Here it splits off and goes to the window switches.
At this point it connects to a single plug and stops at a bare end. I think it supposed to connect to a light on the auto shifter, the light that illuminates the shifter numbers. I could see it breaking off from the shifter and grounding on the aluminium shifting housing.
It appears more likely that the fog light switch fell apart and grounded a lead and melted the whole show. Has this happened to anyone else?
