The pump for the rear window is on the side of the reservoir and the pump for the windshield is on the front of the reservoir
after removing the reservoir gently pry out the old pump and lube the o-ring for the new one with lite oil
No adjustment is possible.
On the bottom of the washer fluid tank.
It is located right on the windshield washer reservoir. It looks like a short black cylinder.
on the drivers side under the hood.
Ummm...I think it would be safe to say that the washer motor is faulty. Do the wipers work when you push the windshield washer button? Good luck, Mr. Dog
It is inside the fuel tank.
Look under the resevoir tank
Hi, I have had the same problem with a 1997 GMC Savana V8 5.7L twice, fuel pump had to be replaced. It did run perfectly at idle but would not pick up speed,found a electrical issue with the fuel pump.
Try replacing the windshield washer pump. There should be two pumps located on the washer reservoir. Simply unplug the electrical connector, pull the fluid tube off, lift them out. Put the new ones in the same place as the old ones. Place the fluid tube back and reconnect the electrical connector. The parts are pretty cheap about 15 bucks each from Autozone. Give it a shot. Overall it should take less than five minutes. Good luck.
If you are putting EFI/or efi engine in a GMC pick up that came with a carburetor you will need to run a KOEO relayed power supply line to the new fuel pump.
