I have a 02, the wipers in delay mode are not working right, they studder and skip. Does anyone know where the delay moudle circuit board is located? Is it on or by the wiper motor?

 

02 ????????

 

IF its a bravada it is mounted on the wiper motor.

 

2002 Bravada I assume.

The skipping and judder is usually caused by:

Dry wiper blades (get new rubber)
Improper wiper blade angle to windshield
Excess wear on the pivioting pin that holds the wiper blade to the arm.

I do not know where the delay board is, but in previous GM cars, it has been in the wiper motor.

 

Yes Bravada. It is not the blades,they work fine when they are on low and high,

 

The problem is in the wiper control module board which is mounted on the back of the wiper motor, on some they can be replaced seperate of the wiper motor on others the motor has to be replaced as a unit. You can test this by Monitor the Gray wire at the wiper module. If it is steady voltage as wipers jerk, the problem is in the motor/control board.

2. If voltage is varying, there is a problem in the switch resistors.

 

Had to buy a hole set up,motor,arms circuit, not bad to change, and now it works,$155, compared to $500 for GM to replace.

 

I had the same problem. The module is screwed onto the wiper motor. You have to take the whole wiper motor/transmission assembly off to get to the module.
