If your Peterbilt windshield washer pump is not working, it may be due to a faulty pump motor or a clogged nozzle. Check the pump motor and replace it if necessary, and clean or unclog the nozzle to restore proper functionality.
Common Issues With Peterbilt Windshield Washer Pump
Here is an overview of some common problems you may encounter with your Peterbilt windshield washer pump
- No fluid coming out: One of the most common issues is when no fluid comes out when you activate the washer pump. This could be due to a clogged nozzle, a faulty pump, or a lack of washer fluid.
- Intermittent operation: Sometimes, the washer pump may only work sporadically. This could be caused by loose electrical connections, a malfunctioning switch, or a worn-out pump motor.
- Weaker spray: Another problem could be when the washer pump sprays a weak stream of fluid. This may indicate a restricted fluid supply or a worn-out pump impeller.
- Strange noises: If you hear unusual sounds, such as grinding or whining, when operating the washer pump, it may be a sign of a damaged pump motor or a worn-out impeller.
- Leaking washer fluid: Leaks can occur due to damaged hoses, loose fittings, or a defective pump. This can result in a loss of fluid and reduced washer performance.
If you are experiencing any of these issues, it’s important to have your Peterbilt windshield washer pump inspected and repaired by a qualified technician.
