wiper motor

1999 Grand Am - The windshield wipers have stopped working. However, the wipers work when using the washing function.

check fuses, but it sounds like the control is malfunctioning. if they work with the wash, then the motors probley not bad.

I had a similar problem with my 97 grand am se, 2.4l, 5 speed. The wipers wouldn't turn on unless I did the spray wash. What eventually worked for me was I left the wipers on accidently after I had spray washed my windshield (by habit I turn on wipers to max as I'm spray washing) and while I was diving down the road they just started working, and I have never had a problem since. Maybe it was a dirty connector somewhere, but they have worked for ~6 months now.

Good luck.

I have heard of the "pulse module" going bad on our cars - it controls the pulse / speeds of the wipers. It might be something to check into. Maybe do a search for it; or try buying a new module.
