my cruise control wasn't working either so I changed the combination switch ( wiper/ cruise control/ hi beam). cruise control works now but wiper still comes on when head lights are turned on (not on park lights ) Had suspension work last week so now I'm checking for loose grounds

Hello. When did this all happen ? Right after work was performed ? What else have you done or tried so far ?

Do you have a volt meter and a test light ? Are you good with electrical diagnosis ?
