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.

Wipers run, but will not shut off.....must turn off key to stop wiper motor.

The wipers will only work on high, and nothing else. Even the window cleaner will not work. When i turn the switch anywhere but on high the wipers will stop wherever they are, even if that is all the way at the top. I have to time it to get them down in the right place.
Wipers always come on--does not appear to be motor issue. Checked wiper control board and no bad or cold solders present. Wipers work in low and high but briefly in delay mode and then default to low setting. Takes a few minutes for wipers to cycle off and stop mid-cycle in middle of shut off.

the wipers either stop when being used or fail to turn on when activated. When in the fail condition you can hear the control box buzzing. If you open the hood and rap on the box with your knuckles the wipers will start again. They have done it about 5 time in the last 14 months. The shop has not been able to have it act up when they have it and if I leave it alone and drive in the probpem is gone when I arrive.

The real problem is that the board is not held tight up against the motor making a poor contact. The problem has been fixed Chevy has a recall that replaces the cover that holds the electronic board up to the motor.

Wipers will not work on delay, and will stop and start.

I have the 2500 series. when I turn on wipers, they buzz and washer does not work either. today they work .someday they will not.
Had the sane problem on my 1997 silverado pickup. it easily replaced by anyone with average mechanical ability. Just take your time and be gentle when removing the plug.

Wiper fuse appears fine. Wipers just stop working.

1999 Suburban Wipers would not turn on - typically when it was raining ! Moving connector would start wipers. At first one wiggle would do it. Then it would only go a couple of cycles before it would stop. Fixed by replaced wiper control board. Dealer told me there was no open recall. From all I have read this is a very common problem !

Wipers would work intermittantly. Changed the Wiper motor pulse board (part number 88136 from Autozone and Advance Auto parts) and that fixed the problem. You can knock on the board with your knuckles to get it work in a pinch if you haven't changed it yet. This will also confirm that your wiper motor is still good.

Two trucks I purchased new. 93 and 94 Silverado. Same problem with windshield wiper as described in other reports. I found my problem to be a combination of bad (loose connection) at the plug on the wiring harness that plugs into the wiper motor housing as well as bad solder connections inside the motor housing from the female plug to the wiper motor control board. This problem was apparently on hundreds of thousands of GM products. Bad design as well a cheap materials and manufacturing. Definite safety hazard that GM should address and fix.

When the wipers stop working I will pop the hood and pull the wires and connector plugged into the wiper motor until the wipers start working again. The fix doesn't last long.

was pouring rain on the way home from a 4hour drive and wipers stopped working... very dangerous as I kept going. They randomly came back on 3 hours later?
