It's likely the pump/motor. There's a number of them on the washer fluid tank. You'll have to figure out which one and order the part. There's likely tons of form/fit/function aftermarket pumps for cheap on Amazon.

The tank is under the drivers side fender above the tire liner. Not terrible to reach after taking off the wheel and liner.

Here's a good few view of the tank in this thread

Since I'm moving to larger than 35s I ran into the issue with the windshield washer tank. I think I want to make a 1" shorter tank that fits in the OEM area that retains all the stock pumps\sensors. So I scanned the area after my inner fender raise.View attachment 4145068

The stock washer tank is surpisingly complex with the number of pumps and interfaces.

It's a game of millimeters and there's a couple things you can do to increase tire clearance against the tank. Not sure if it will be enough.

The tank is hung on the inner fender and has about a 1/2" clearance all around. I imagine it...
