Tahoe headlight and windshield washer issue

Hey, I have a 2004 Chevrolet Tahoe with a gasoline engine. My headlight cleaning system isn't working. The windshield washer system also stopped working at the same time. I checked the fuse, and it seems fine. Any ideas?

A 2004 Chevrolet Tahoe experienced simultaneous failures in its headlight cleaning and windshield washer systems. The fuse was checked and found to be fine, leading to suggestions of a defective or corroded cable connection, a clog in the hose, or a system leak as possible causes. The issue was resolved by addressing a defective cable connection, confirmed by a visit to a workshop.

I had a similar issue with my Tahoe. Check the cable connection of the pump. It might be defective or corroded. Also, see if there's a clog in the hose. A leak in the system can also cause both systems to fail. It's worth investigating before you start replacing parts.

Thanks for the tip! Where exactly is the pump located, and is there a relay I should check as well?

The pump is usually near the washer fluid reservoir, often at the bottom. There is a relay too, but if the pump cable is defective, that is more likely the cause. I would suggest to visit a workshop.

Thanks! I took it to a shop, and you were right – it was a defective cable connection. Cost me 165€ to get it sorted.
