🔥 Dorman 973-409 HVAC Blower Motor Resistor Kit: High-Performance Upgrade for Cadillac, Chevrolet & GMC Models Review

Perfect for my base 2000 Silverado 1500. It only took 15 minutes to put on. I didn't have to change my seat belt because mine didn't get hot. Now my fan works on all settings, not just 4 and 5.

After some troubleshooting and YouTube, I found that this resistance was the reason why my Silverado wouldn't run at 1-2 speeds, only 3-4-5 speeds . This fixed the issue and now my HVAC system in the Silverado is running like clockwork. Delivery was quick, packaging was simple but secure, and installation was a breeze.

Sellers claim this unit will replace the 06 Silverado HD unit. While this "electronic" may be true, it is NOT EXACTLY original equipment due to the mounting holes not being aligned. I would have sent it back, but since I had to cut the multi-plug harness on my old unit to disassemble it, I had no way of comparing the two units.

Fits my 2001 Silverado 1500 LS Long Cab with 5.3L Short Bed. The fan stopped working at speeds 1 and 2 but worked fine at 3-5. This replacement looked a little different than the OEM part it replaced, but it is well bolted and plugged right through so no bonding or soldering is required. The fan now runs at all speeds. I also changed the cabin filter while I was there. They were badly clogged which may have damaged the resistance.

My 2003 Silverado 2500HD Speed #5 started working intermittently and eventually stopped working. I removed the resistor to verify the part number before ordering. 15305077 which is intended to replace this part. The electrical part works fine but the mounting tabs were wrong. The adapter plate from the original didn't help either, since the position of the relay and connector is different. Both sockets were fine. I didn't want to wait for the right part or the hassle of sending it back and…

This part was listed for my Avalanche. However, GM, in its boundless wisdom, decided to prank self-repair enthusiasts and made this part in both left-hand and right-hand versions. There is a bracket that this part fits into and then bolts on. Also, the 7-pin connector is slightly angled on the old part, and straight on the new one. The tabs that hold the part in the bracket are also warped, and the new part was mostly warped to the opposite side. I plug it in to make sure it works in my truck…

This was installed on a 2000 Chevrolet Silverado 1500 4x2 Extended Cab. Fits like a baby glove! Solved my problem at all (first two fan speeds didn't work); the other three were not very strong). Now all speeds work and higher speeds are POWERFUL. Been up for a few months now and still works great. Accessing the area isn't a problem, but getting the screws back in place isn't that easy. Removing the cover from the fan assembly took about five minutes. Replacing the resistor kit took about three

Item does not work as described. Revane says he's coming to my truck, but he's not coming. The screw diagram is completely wrong. When I plugged in the wiring harness to at least test it, I wasn't surprised that it didn't do anything after turning my fan speed down by 1, then 2, then 3, 4, and finally 5, and it didn't do anything. It costs me at least $6 to send back which is not worth my time so I have to swallow it as a waste of money. My truck is a 2003 1500 GMC Sierra 4x4 4.8L regular cab…

First let me say this product is great. It's usually around $40 at local auto parts stores, and I bought mine here used/like new for $10. So the lack of instructions is what stinks about this product. Fan connector, do not try to remove the round black fan cover. Find someone with very thin fingers instead, or take a screwdriver and try to pinch the clip holding the fan connector to the motor. (The plug is inside the fan shroud.) If you decide to remove the two screws that hold the fan shroud…
