My son has an 07 Mont Carlo that has a non functioning pump.
I was trying to figure out where the fuse may be located if there is one. He has no manuals to go by and I figured to find that first before replacing the pump.
Also will check hoses after but don't see leaks. It's just not making any noise.
Thanks!

 

I looked for location in my Haynes Repair Manual.

In the underhood fuse block, there is a 25 amp fuse for wipers.
There is a wiper low relay, wiper high relay and a washer replay.
Washer relay is what you want to check.

 

Thanks TomF1066!
I actually found the fuse labeled "WSW" under hood and replaced it since it was blown.
Windshield washer sprayer now working!
