Just got a 97 f150,if I turn the wipers on while the truck is running nothing happens,if I turn them on before I start the truck they will cycle once then do nothing. I repaced the turn handle switch and no differance,any ideas

 

Have you checked the relay and the GEM?

 

No I havent what is the best way to go about checking those

 

Relays can be swapped with a known good relay.

 

 

Burnt spots? It sounds like it needs to be replaced.

I'd replace it, and make sure the fusees are the correct amperage for each location!

If you don't know what the fuse amperage is, consult your owners manual. Go through each position one-by-one.
