Body & Interior
Why does my new power window regulator work backwards? Goes down when it should go up.
When i plugged in my new regulator the window worked in reverse. When I push he button down the window goes up and vise versa. Thinking the new part was defective, I exchanged it. Still the same results.
Reverse the polarity of the two wires at the plug, cut and strip insulation and use butt connectors to reconnect, done. Seen it before.
