Why Won't the Mercedes Windshield Washer Spray?
1 Answers
Reasons why the Mercedes windshield washer won't spray are as follows: 1. If the Mercedes washer isn't spraying, first check if the pump motor is working. If not, inspect whether the fuse is blown, if the wiring connections are secure, or if the pump motor itself is burnt out. 2. Check if the water hose is cracked, if connections have come loose, or if the nozzles are clogged. Cracked hoses need replacement, loose connections should be reattached, and clogged nozzles can be cleared with thin wire. 3. If the reservoir has water and the motor is working, you can disconnect the hose below the nozzle and activate the washer switch. If water sprays from the hose, the nozzle is clogged and can be cleared with thin wire.
