strange windshield wiper ghost '94 s10 Blazer

When I start the truck after it has been sitting for at least a half hour or more , the windshield wipers cycle one time. Anyone have an answer/ solution to this?

Probably the wiper module.

If memory serves me correct the part number is 12463017

We have seen lots of problems with these including ghost wipe.

Thanks, I'll check out another module.

Check with your dealer first. GM just sent out a special policy covering certain years for an extended period of time.
