ACDelco GM Genuine Parts 19120931 Windshield Wiper Motor Pulse Board And Cover, 3.96 in

The photo in the part description is very poor, however when the part arrived, it was the correct one. I installed it and my problem was fixed.

This product worked perfectly! My windshield wipers were stuck on intermittent, and wouldn't turn off. I had several people try to convince me that it was the wiper motor, but the wipers were working, they just wouldn't turn off or work at a different speed, so I knew it had to be some other problem. After researching, I found that this particular part frequently goes out and it causes the same exact issues that I was having, so I purchased this part and hoped for the best. I found a few YouTube videos that have the basics on how to install this part, but they weren't very detailed. I found several different discussion boards that had various tips and how-to instructions, and just put all the information together and gave it go. You have to remove the wiper arms completely to get the plastic cover off in order to get to the part where the relay board attaches. I wish I would have taken video of the actual process, but it was a trial and error method, so I have no video to share. I had a difficult time getting the wiper arms off and finally found a tip that you should raise the arms to release the tension on the spring while trying to pry them off and that was definitely the missing key. I purchased a battery terminal puller as several people recommend, but it didn't work, I ended up using a wrench and had to work the wiper arms back and forth while prying upward with the wrench to get them to come off. After finally getting everything removed and actually getting to the area where the part attaches, it was a breeze from there. The board fits perfect and the plug slides easily into place. This part looks exactly like the factory part and everything lines up exactly as it did with the old part. There is a small plastic dial that you have to make sure is in the same position as the one you took off. This product is much more cost effective than having a repair shop do the work. If you have any sort of mechanical ability and a little patience, you should have no problem installing this part. I am so glad I was able to find this part and not have to pay a repair shop to fix it for me. This was much cheaper than anywhere else, and works as stated. If I have any issues in the future, I will update as necessary. I am super stoked that I have functioning windshield wipers again!

On my 2006 Trailblazer the wipers went crazy. Wiped whenever they just got the feeling to wipe, so temporarily I had to remove the fuse. As I got the part I realized that I will need a puller to remove the wiper arms. When I ordered a finally got those too, It was a good 40 minutes to replace the pulse generator. GM engineers could hide this sensitive electrical panel anywhere in this huge ass car, but they picked the best location to get all the dirt, water and all other elements of weather on it on a daily basis. So as I thought the thin rubber sealing was blown on the original part, and oxidation did rest of the job. The complexity of the board does not even explain the price, so 2 stars for value for money is still too kind from me.

Watched videos on YouTube on how to change this and it’s relatively straight forward. This is a original GM replacement part and works as it should. Very satisfied with the fast delivery and the fitment.
