Installed resistor blower heat sink 4/2018, required a lot of work to mount on the heat sink like the original. Blower motor quit running today 6/16/2020 Car is not used every day and only has 3115 more miles sin install!! China made piece of JUNK! Its a shame the original MFG quit making the resistor attached to the heat sink. Frustrated!!Tip If you install one of these run blower on high speed only. It might last longer. It dose not get as hot on high speed.

The male pins on the gang plug are smaller than the original so they fit the female sockets of the body harness way too loose. We had to cut our old harness off and splice it to the new part. Once installed it did not work properly so the heater fan would not work on high speed, the longer it ran the hotter the blower control got to the point of melting plastic creating smoke.Don't waste your time on this part.

Some modifying to the heat sink required---grind off tab on heat sink base---drill new holes for mounting of this product to original heat sink---Grommet for wiring is made of hard plastic, not rubber, so it will not fit into hole of original grommet for weather protection, have to cut slice in it to make it fit---to plug it in you must cut the tabs off of the center of the factory harness with a razor blade---and good luck with the so called directions sheet. This was installed on a 2000 Mercedes Benz SL 500---One week later customer was back with an inop blower motor---This part went bad that fast. Amazon was quick to send us another one, but if it goes out, we're never using these again.

It all started when my air conditioner blower worked sometime .then it stopped working altogether,that was the Telltale sign of the blower resistor going bad .The new one from Mercedes cost well over $700. Then I stumbled on this resistor that looked very similar to the one on the car except the aluminum cooling plate underneath it in which I had to detach it from the old part ,and attach it to the new one it took some effort to do that but now my air condition works like new again. It's definitely a perfect fit !!!! I would recommend it to anyone that willing to invest an hour to separate the aluminum cooling plate and attach it to this part .On the other hand, if you're looking for a perfect swap this part it's not for you.......

The mechanic quoted $350 for putting this into my car. My 22 year old son watched YouTube tutorials and installed it for me in less than an hour. So glad that I purchased and saved myself so much money.

Item shipped was an incorrect part number. It does not fit my SL500. Because of vacation, I wasn't able to get the car scheduled for repair until I was outside the 30 day return period. Now I'm stuck with a part that doesn't fit my car and all I can get when I call their "Customer Service" is an unanswered phone (not even a voice mail). DO NOT DO BUSINESS WITH 'PartsSquare" !!!

It was a paint to reach the item inside my engine bay, but that's not the product's fault. Installed simply and immediately got my HVAC system performing perfectly.

It was not a oe replacement
