Wiper Motor

06-21-2010, 08:47 AM

My wipers on my '97 Jimmy work sometimes, and sometimes don't. I'm not sure if it is a switch issue (located at turn-signal arm) or a wiper motor issue. Can someone please direct me to any previous forum discussions/threads on this?

Thanks in advance!

Bolted to the wiper motor, (under the hood) there is a circuit board that the wiper motor electrical connector plugs into. The solder joints become corroded and break loose. Very common problem. You can try to re-solder them or replace the wiper pulse module:
