So I’ve been having issues with my wipers. The pump doesn’t work and I don’t have any variable speeds. Every now and then I’ll get it to wipe on high, but most cases it just does a single cycle. I have looked at the fuse diagram to see if it’s a relay or fuse but the diagram only shows the wiper motor fuse. I can’t seem to find the relay anywhere on the diagram.

Hello, I'm Danny.

Here is the information you requested. The wiper motor relay is located in the under hood battery junction box. Here is a tutorial showing how to test a relay as well as electrical wiring:

I've attached a picture below showing the wiper motor relay location and circled in red. I've cut the wiper motor wiring diagram in 3 pieces so you can view larger. Let us know if you have any further questions on this issue. Hope this helps and thanks for using 2CarPros.
