Maybe? search "Wiper Switch Fix" on here. I posted a few pics.
If it is non responsive when the weather is cooler and seems to work intermittently....could be a simple solution.

 

Ok so here is the update. I checked all the fuses I checked the relays and swapped them with yellow relays from the (under hood fuse box) to check if there is a difference at all. None. So the Relays must be fine. Now, my only assumption is that the actual switch is in need of replacement. The rear wiper will not go either, but the pump does spit water out with I hit the button on the dash/next to the steering wheel.

So its odd to me that the pump works for the rear, but the wiper wont move, along with the wipers and pump in front they have no action.

I checked the schematics and it seems they are all on the same system, am I wrong and missing something or?

I was thinking of pulling out the switch tomorrow and testing it. But what I'm curious about is the rear pump and why that shoots water but the wiper wont move?
Could it be an BCU issue or IDM? I'm confused at the moment I swear!

Thanks!

@CANAM I actually just finished reading that thread and like it being very detailed. I will consider doing that tomorrow. I just want someone to answer the above and inform me etc.

Thanks for the mention!

 

Are those relays at the bottom (top of back) of that internal fuse box? They don't look like them. Which one is the front wiper relay?

 

If your wiper motor is acting up it’s probably the motor

 

I cannot believe how impossible it’s been to get a direct answer to this question. Everyone offering up everything but an answer.

 

Savannah Buzz posted the attachment of the wiper circuit showing the relays and fuses to help everyone.

 

Which was super helpful, yes. There is a relay there, electrically. But physically? Is it on the back of the fuse box? Internal? Is it replaceable separate from the fuse box?
