Review on 🚘 20785187 GM Genuine Parts Windshield Wiper Motor, 9.25 inches by Doug Small

At first I was suspicious because it seemed too good to be true. I first bought a remanufactured engine from a retailer and it cost over $100 MORE, not even the base rate. Revain didn't charge for the core and was still over $100 cheaper when you ignore that fact. I wondered if it didn't contain something I needed, but it was actually more than that: the rebuilt part was just an engine; This is a new motor, plus 3 bolts and a nut. Everything is ready for installation. All I needed was a few tools: a flat head screwdriver, a 13mm socket wrench, a 15mm socket wrench, a wrench (handy for tightening a nut on a motor) and a Torx T30 screwdriver. Problem. The wipers seemed to stop working when it was very cold outside (10 degrees and below). The brushes inside the motor can wear out, the grease can age and the material inside can thicken, especially at very low temperatures. I also heard a very faint click near the wiper motor as I toggled the switch on and off, which told me the switch was probably fine. You can use a test light or multimeter to test the switch, but it still requires you to take things apart to expose the wiring harness. The only problems I had were unrelated to this engine. Disconnecting the wiring harness from the old motor was not easy - the temperature was 14 degrees, the plastic was brittle and in the end it broke. It still fit snugly in the new engine. The other problem was that after I installed everything, the wipers tried to wipe in the WRONG DIRECTION! However, this was not a problem with the engine; The motor rotates in only one direction and relies on the transmission armature to cause oscillating motion. This means the position of the arms matters when reconnecting the wipers - I had to remove the wiper motor/gear assembly again, loosen the nut slightly and rotate the small arm connecting the motor to the gear arm 180 degrees. Got it and everything works great. When reinstalling, be careful where you put the wipers as you may only notice very little downward movement before they go up and you want to make sure they don't hit anything. I installed this in a 2009 Buick Enclave but I know it has worked for several GM models for several model years so check before you buy. I found a great video online detailing how to install this. So look in the obvious places if you need help. Anyway, this motor has worked great for me. Luckily the dealer allowed me to return a remanufactured engine I bought before I found this one.
