This Q is for you GM pick-up owners, The windshield wipers on my (01)Sonoma have decided to quite working when I need them the most. I checked the fuse and its not blown. Is there a relay that I may be overlooking?

 

Call dealer to see if recall applies to yours, if not do this.

How to repair GM intermittent wipers,before starting pull the wiper fuse or disconnect the battery.Disconnect the electrical plug from the motor,remove the screws holding module to the motor assembly.Remove the module from the motor assy,you may have to pry it loose with a flat blade screwdriver where it plugs into the motor.Now where the plug attaches to the circuit board there are 5 soldered pins,if you look with a magnifying glass you will see the cracked solder,I resolder all five pins.Use a large enough solder gun to get a good melt,I also add some fresh solder with some electrical flux.Reverse assy.

If not handy with soldering just replace the wiper module.

 

Thanx, appreciate you imput.
