98 Blazer wipers will just stop. If I turn the switch off and on they will start back for a while and quit again. Same thing over and over. If it is the switch, how can I fix? Thank you for any advice. Al

 

It is quite possible that it is a problem with the wiper pulse board in the wiper itself. Many GM truck wiper motors have problems with cold solders on the circuit board. Here is a How-To I made up quite a while ago on how to check for this.

 

Thanks, I will try that.
