Relay help please
 

92 500SL- Headlight washer pump wont turn off [have unplugged it], found relays by the firewall under the fuses, which relay controls this pump? Suspect the relay is stuck but dont know which one it is

Any help is appreciated!

Plug the pump back in then unplug the relays one by one until the pump stops.

That was the subject of a RECALL back in 1996..(campaign 96-1113) The w/s washer motor got so hot that the washer bottles caught on fire..

The real problem NOT covered by the recall was the RIGHT headlight wiper motor that controls that system.
