hello and thank you in advance
the problem that I am having is the only speed that I have on my wipers is high it started where it would work sometimes on each setting and then just started to where it was just high that would work I did not know if it would be a relay which is cheaper or a multifunction switch if you could help I would greatly appreciate it.

Hello,

Yep let's get this problem fixed it sounds like the switch has gone bad but to be sure let's do some quick tests. First the wipers are controlled by the BCM so lets check all bcm fuses becasue if one is bad it will cause this problem.

and there are three relays that run the system as well.

Here are the windshield wiper wiring diagrams and fuse with relay locations (below)

Please run this test and get back to us.

Cheers, Ken
