Has anyone had this little gremlin: wipers work fine in pulse/low/high for awhile, then fall to off position while driving. At this point, will only work on high. Move the stalk to 'off' position....let it cool down?....turn 'em on again and they work for a while and then die again...
I'm thinking the wiper MFS on the steering column...but looking at the wiring schematics for the connector goes through an awful lot of circuits before getting to the wiper motor. Ideas?:banghead:

It's probably a faulty wiper motor circuit board (AC-Delco #12494773). When they start to fail, they will cause all kinds of problems with the wiper operation.

Thanks!

BTW, is that the pulse module on the wiper motor itself?
