TITLE: Wiper/Washer Will Not Turn Off or Other Possible Issues
APPLIES TO: XXXXX XXXXX
Some customers may comment that the wiper motor, or washer pump will not turn off, etc. These concerns have been isolated to internal issues with the control module.
Verify concern and refer to the Service Manual for proper diagnostics. If condition is present, replace the wiper control module only, not the entire motor assembly. The wiper control module may be referred to as the wiper motor "cover kit" or "circuit board" in the parts catalog.
Any instructions on replacing the module? Also, would help if you can provide a part number for the latest and correct part that can be utilized. This would close and satisfy the requirements.
The procedure says to remove the wiper transmission to replace the control module or "wiper motor cover." But you may be able to replace the control module without removing the wiper transmission. The replacement part number is XXXXX Delco 19120931. You can get it from Rockauto.com
