Upgraded Design Heating and Air Conditioning Blower Motor Resistor Module for Buick Cadillac Chevrolet GMC Oldsmobile Pontiac # 4P1516 MT1805 RU-631 JA1639 BMR34

So this part works great had it in for a month so. The price was so much better than the parts store. Will buy again if I ever need again.

AC blower kept running after I shut off the vehicle. After searching the internet I found an article that pointed me to this part. Plug and receptacle fit perfectly so no re-wiring was required. One small caveat. Now after I shut off the car the blower runs for a second or two before it shuts off which was not the case before but it shuts off and AC is good to go so I can't complain.

Exact replica of my factory resistor. Works perfect

Update Jun 2023: here we are 7 months later and it has completely failed- filling my truck with horrid smoke and could've probably caught on fire if I didn't happen to be in it since it has power 100% of the time. I knew exactly what it was and so I was able to react and literally rip/tear the wires right out while pulled off the side of the road and half into the ditch! I knew it was garbage when I first got it and shoulda never installed it.Original review: October 2022 Well this wasn't the best experience. I ordered this part because it was $50 less expensive than my local parts store. When I received the part I immediately noticed the wire crimp had broken free (it appears it just wasn't crimped well. I thought no problem- I'll just cut of the end and use the plug from the factory (OEM) part. Well much to my surprise - this module was defective and when I plugged it in the blower motor spooler right up to high just like the one I was replacing. For just a second- I thought I had mis-diagnosed the problem. Since they're easy enough to remove- I grabbed the one from my other truck and it worked perfectly. Dilemma now of course is that I cut the wires off the first one and spliced on the old connector. That'd have been fine, and is pretty much standard practice for lots of the replacement resistors- but now I'm trying to return it and I fear I'm going to be disappointed with the outcome. Outta respect for the thought I mighta just got the "one bad one" I've ordering another of the same and hoping that Amazon refunds me for the first. We'll see. If its the case that I did indeed get "the bad one" - I will happily update this review accodingly.

It was just what I ordered.
