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: http://shop.advanceautoparts.com/webapp/wcs/stores/servlet/product_Wiper-Motor-Pulse-Board-Module-Motormite_5910000-P_2040_R%7CGRPWIPEAMS_837588059___
