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

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!

You'll pay more at a dealer for this OEM part, and even more to have them install it rather than doing it yourself. The hardest part about the installation was removing the wiper arms, as mine did NOT want to come off, but with a bit of leverage under the arm, unscrew the retaining nut until it's flush with the arm pin and tap the nut with a hammer using moderage force until the arm loosens. For the 2007 TrailBlazer, there are 2 10mm nuts (I think they're 10mm) in the cowling, and then there are 3 push-pins that you'll see after opening the hood. You can remove the radio antenna if you want to (I did) and then the cowling will come out and you'll see the wiper assembly. I did the job 2 days ago, and I've forgotten a LOT since then, but I think there were 13mm nuts that held the wiper assembly on. Once those are off, unplug the wire harness, remove the 4 torx screws holding the motor pulse board to the main assembly, and remove it. Your new one will fit on just like the old one did (note the position of the '"thing" inside), and then reassemble. ONLY COMPLAINT: GM, for whatever reason, chose to include only 3 new screws in the box, so don't throw yours away, as you may need one.

My wipers stopped working one day on my truck. I did a little research and discovered that these modules are known to fail on my vehicle and that replacement was no big deal. I ordered this module, installed it and it's been working great ever since. Fit exactly like an original GM part. I had this module installed in less than an hour. Anyone with basic mechanical skill can do it and it will save you an expensive repair at a shop.

Removing the wipers on my 2006 Trailblazer was a little difficult. There is a video on YouTube that explains best how to do this. I found removing the 4 torque screws on the wiper module the most difficult task. Mine had a little rust on them. After spraying them with WD40 and letting them set for about 10 minutes, I was able to remove the torque screws. After reassembling everything seems to work fine.

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.

I received this part, very securely packaged, on time. It was very easy to install, you only need a 10mm wrench and a hex-type screw driver. I thought this would be a real pain in the (you know what) to install. Basically, the windshield wipers need to be removed, then the protective plastic cowl under the wipers, a snapped on felt-like "blanket" cover, and finally the windshield wiper motor assembly. Sounds complicated, but I'm telling you I did it all in about an hour and ten minutes. This part sits on the back of the motor assembly, and has 4 hex/star shaped screws and a connector plug to remove. Wished I hadn't been so afraid and changed this thing last August when the wipers originally went out. GM makes some crappy products.Had to change this myself, because they really DON'T stand by their products.If you have wipers that won't turn off at all, this is the fix for it. I would not recommend paying the dealer in excess of $500 to change this part, which is what I was quoted. I saved right at $405 doing it myself.
