i cannot turn off the wipers..I disconnected the battery for a couple of hours and then started the car and the wipers stayed off but as soon as i hit the radio button they came back on.I took it to a friend of mine and he says there is no relay or fuse that he can check and a new switch is $400 plus install...Any suggestions would be appreciated...This is my first post ...

Two threads to go over:
1. General common problems thread. 2000-2005-other-than-gxp/topic25362.html
2. Thread specific with what is most likely your problem: viewtopic.php?f=21&t=15390&hilit=wipers&p=161391#p161391

Oh and welcome to the forum.
