Take the wiper moter cover off and you'll find it easy to change out.
The board is under the cap in the Wiper Motor.
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.
figured it out on my own since no one here was able to help. the pulse board(circuit board bolted directly onto the wiper moter) has an internal relay that is sticking. i replaced the circuit board.
there is small circuit board mounted on wiper motor. Circuit board available at Chevy Dealers or IWI motor parts. No need to remove motor but micro stubby screw drivers needed to remove and replace. worked great.
sounds like the printed circuit board is causing the problem. on some wiper motors you can purchase the circuit board separate from your local auto parts store. and replace it without removing the wiper motor from the vehicle.i hope this helps you out.
I have a 1994 Sentra, and the relay is inside the steering wheel assembly, soldered onto a circuit board.
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.
chances its not the motor but the wiper module board located on the wiper motor. just remove the wiper motor and the module board is connected to it.
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.
The wiper relays in my 1995 Safari were inside the wiper motor housing. They kept going out because water would get into the housing. If you unscrew the front of the cover, you will see the circuits and contacts. YOu can clean the contacts, but the best bet is just to replace the entire thing. on my 98 safari i thought water was getting into my wiper motor, since the only time they acted up is when it was raining,and they would work - when they felt like it - or when i would flex the wiring connector which led into the wiper motor - called my dealer they said it would be the circuit board, I removed the screws from the cover of the wiper motor which is the circuit board and with the wiring harness still plugged into it i pulled it towards me to reveal the components on the other side, the relay is the first the you see when you follow the wiring into the circuit board, you will see 4 to 5 solder points connecting the relay to the circuit board, these solder joints worked loose, to repair simply resolder adding additional solder. The boards are releativley cheap at the auto stores, but before spending the money try unplugging and replugging the connectors to the boards.
if the new motor came with a new circuit board (wiper pulse board), then the only thing left is the switch on the steering column
The main circuit board of the computer is the motherboard.
