The wiper motor can be replaced reasonably easy, however your particular problem is usually caused by the circuit board that controls the wiper motor and the delay cycles, retraction, etc. The board is also quite cheaper than the entire wiper motor. It is also called a wiper pulse or relay board and can be found online from around $25 and up. The electronic board plugs into the wiper motor, and the electric cable plugs into the circuit board.
There could be a bad or melted electric connection on the wiper switch connector.
it seems to me that you are having issues with the body control module as this module controls your intermittent wiper speed and the rest of the speeds are controlled directly by the wiper switch . regards , ashish
Either a few wires are now unconnected or you just need a new Windshield wiper motor.
an intermittent wiper has a built in delay , wipes once then waits and wipes again, speed depending setting you put it on, non intermittent wipers dont have a delay and keeps going until you turn them off, no waiting, wipes, hits bottom and wipes again right away
The multi-function switch inside the steering column has the turn signal lever and hazard lights button extending outside of the steering column it operates - turn signals - flash to pass - high beam headlights - windshield wipers ( on/off ) and intermittent speed settings for the wipers - windshield washer fluid squirter button
by introducing resistors in the circuit
Have the speed sensor replaced.
General Motors had a recall on some of the delay modules. Call the dealership and give them your vehicle identification number and have them check to see if it applies or if there are any that have not been done. It is free and it does not matter if you are the 5th person to own it. A RECALL is FREE, a technical service bulletin is NOT.
The resitor is probably burnt out on the high mode
Bad switch? stalk bad wiper motor? bad low speed winding
It was the fan motor
The wiper relay is located behind the fuse box, third socket from the drivers side. This relay controls the low speed and intermittent functions. It also controls the motor to "park" the wipers down rather than just stopping them. The 1st relay is for the E-flashers and turn signals and the 2nd relay is for the low/high beam headlights.
