This is really an easy fix. The wiper motor assembly is on the firewall, just right of center. The wiring can be unplugged before the circuit board is removed, or afterward. I found it easier to unplug it after the circuit board was removed.
There is a flat cover that is held on with three torx screws (T20). Remove those screws and remove the cover.
The circuit board will now be visible. Remove the circuit board by grasping the wiring connecter and gently pulling it towards the front of the vehicle. When the circuit board has fallen free, unplug it from the wiring harness if you haven't already done so.
The solder joints that connect the wiring socket to the board were bad on my board. I just resoldered those and re-installed the circuit board. I did get an entire wiper motor assembly, which included the board, from a salvage yard for $40. I didn't even use it.
Excellent answer!
My wipers would not start without getting out and helping, then they might or might not continue running after a few wipes. When switched on and not running, module would produce buzzing sound.
Followed directions above, and even though the three pins joining the wiring harness plug to the circuit board looked properly soldered, carefully re-soldered making sure to have good solder contact to printed circuit strips.
In my case this worked like a charm, and judging from the number of postings for this fix, it seems to be a common problem with this board.
It would seem to be a good first step unless there are other obvious signs of failure.

How do you repair wiper motor on a 1997 gmc sierra?
The wiper motor rarely goes bad. Request what is called a pulse board. Remove the front panel from the motor disconnect the circuit board (pulse board). Replace board. Place bead of silicone sealent around where panel reseals. You also might want to check with your local GM dealership. There was a recall on many wiper motors for 88-98 trucks because of faulty connections on the printed circuit board. I had the recall done on my 95 even though I had bought the truck used because the VIN had never been in for the recall before.
Intermittent wipers dont work 03' silhouette They work on high speed no other speed will work As soon as I take it off of the high speed the wipers will stop and not park Fuse is fine help?
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.
How do you replace the wiper motor on 1998 Chevy S10?
I have found that most S10 (GM) wiper motor trouble is caused by a faulty pulse board, not the motor itself. It is easy to replace and your local auto parts store can sell you an aftermarket pulse board for aprox $20. The wiper motor does not have to be removed to change the pulse board. Unplug the wire harness from the motor, remove the three small screws holding the cover to expose the pulse board then wiggle the board straight out. Reverse order to install.
Where is the pulse board on a 1998 Chevy s10 wiper motor?
It is attached directly to the wiper motor. Remove the three small screws that hold a black plastic cover on the wiper motor. The pulse board is under that cover. Most of your wiper motor problems are from a faulty pulse board.
