The windshield wipers may not work intermittently due to a faulty wiper motor control board. Our technicians tell us that lightly taping on the wiper motor when the fault occurs should temporarily get the wipers working again. Some vehicles were recalled for this problem and some were not. You will need to check with your local dealer to find out if a specific vehicle was included.

The wipers will work one time. The next, they won't. Then they will work. Very difficult to trouble shoot.

It used to be you could tap the wiring harness that plugs into the side of the wiper motor and it'd start back up. Now they only turn on if the temperature is below 20 degrees, and once the truck warms up--they will quit. You get the buzzing/humming, also the wiring harness wiggles probably a centimeter fore & aft... I don't think it supposed to do that. Mechanics want to charge $150+ to fix it... apparently the part is only $40-50.00 at O'Rielly's/AutoZone.
Sometimes wipers would not work. Took off motor cover on fire wall, looked at PC board. Found a cold solder joint for component on bd. Resoldered joint wipers now work fine. Before purchasing a new board.; check this problem out.

Windshield wipers would not start working when I encountered a heavy rain, had to pull off the road & wait until I could safely see to continue driving. I found there was a recall NHTSA #98V150001 issued on 7.01.98 for replacement of a faulty circuit board on the wiper motor. I called the dealer to see if they would handle the recall & was asked if I had ever had my vehicle in their dealership. I explained I had bought the vehicle new from the previous dealership which they bought out. I supplied the requested VIN number & was told my vehicle was not included in the recall even though I was experiencing the issues listed under the recall number I gave them. They transferred me to another area which didn't answer the phone so I left a detailed message along with my contact number. They have never returned my call. After six new GM vehicles, this type of service may indicate it us time to try another brand vehicle. Very disappointed in my dealers lack of service regarding this situation.

Windshield wipers will start and not turn off. You have to turn off ignition and they stop where ever they are. Start the truck again and sometime they will cycle an return to the off position. They do not like to work in the rain. So entires in the wash mode. At first if you taped the motor they would work.
