[petesvx2]

this could take awhile....ok, i was washing my car yesterday and getting it all squeaky clean, im not very mechanical or anything and my svx is my first car but i do know when something is not good. i was planning on moving my car to the shade and using my wipers to wipe off the excess water and when i turned my car on the "check engine" light came on and the car wasnt running the same as normal, when i tried to use the wipers (both rear and front) they didnt move at all. i was wondering if anyone has had a similar problem or knows what i should do. the "check engine" light doesnt stay on all the time it flickers on and off
