    I went in my steering column and tightened the bolts yesterday. After I drove around the power window switch got hot and started smoking. I was able to unhook it before anything major happened. I just need a new switch and the connector. Could this be related? I disconnected the battery just to be safe. Any suggestions?........1SG(ret)

    I did not know I pinched a wire! I would think the fuse would have blown first.

    Directly above the column support bracket is the OE power window relay for 70-79 cars. You may have pinched the main power 12ga pink lead. The 10ga orange supply is fused at the panel to the relay but not from the relay to your switch. And yes...that is a design fail imo from GM.

    No-1980/81 cars have a resettable circuit breaker at the WDO fuse panel cavity, no relay. Once you cycle power off then back on with the key it resets if there was a short.
