Hi, I'm Mike Green. I'm one of the owners of 1A Auto. I want to help you save time and money repairing and maintaining your vehicle. I'm going to use my 20 plus years of experience repairing and restoring cars and trucks like this to show you the correct way to install parts from 1AAuto.com. The right parts installed correctly, that's going to save you time and money. Thank you and enjoy the video.

In this video, we're going to replace the blower motor on this 1986 GMC Jimmy. This blower motor does fit a lot of different applications. The tools we need for the Jimmy are a 6 millimeter socket and a 7 millimeter socket and a ratchet handle with an extension and flex joint. Now, that may vary depending on your application.

The blower motor in these trucks right there at the passenger side under the hood. Okay, here it is. There's a ground strap connected to it with a 6 millimeter or a quarter inch nut or bolt. There's a lead that goes into it. I'm going to cheat here slightly with an air ratchet. There's one, two, three, four, five bolts over here. The easiest way to get to the bottom of this one is with a flexible joint and a hand tool then the motor comes right out. Our motor here is making a lot of squeaky noises so we're going to replace it. Okay, typically one of these motors is making a whole bunch of squeaking noises at low speed.

Here's our original motor and you can hear it squeaking. Here's our new motor, no squeaky. You can see, everything is exactly the same as the holes and tubes, the plug ins. Over the other side, the range is all the same, basically new and clean so it's ready to bolt in. Okay, obviously to get the motor back in, you'll line a pin right here. Okay. Try to put the motor in here. You know the plug is down on the bottom. That seems to work well. Let's start one screw in, then a second. I'll fit the first one in the bottom, I'll get it snugged and then I'll tighten the other ones up snug and then I'll tighten them tight. It don't have to be extremely tight because you are just going through plastic.

Attach the ground straps to the new motor. You generally have to get the bolt in, pull and then press your wrench in and it kind of spread itself in. We can plug in the lead. Okay. Now, I'm going to go in the car and turn on the pin and see if everything works well. As you heard, everything is working well.
