Yesterday, I got my car back from the stereo shop and it was raining slightly on and off. I tried using my winshield wipers by pulling downwards on the wiper lever control and the wiper would attempt to move slightly and stop. Then on my instrument display a red light "I think - EPM light comes on. Everything else works on the winshield wiper control like if I just turn it on normal, fast, intermitent and the squirter control. Anyone ever experience this problem before?
