Hi I am Mike Green. I am one of the owners of 1A Auto. I want to help you save time and money repairing or maintaining your vehicle. I am going to use my 20 plus years experience restoring and repairing 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 resistor on this Impala. You know when you need one of these if your fan only works in four or five or one or two. Basically you are missing speeds and lots of GM vehicles use this resistor. The procedure's probably similar; although, maybe small differences. For this vehicle we needed needle nose pliers, a flat blade screw driver, a 5mm socket and driver, a T20 Torx Bit driver with a ratchet extension, and a flexible joint.
Start by removing this lower panel. This clip there and clip there and there's also a pin that holds it right there. What you want to do first is take a pair of needle nose pliers. Kind of push up on the panel and get the pliers in there. We'll fast forward here a little bit as I just kind of work the pliers into that pin and pull it down. These clips; bring the panel down and you can unhook your curtsey light. Now you are going to remove this bracket that's next to the motor; it's two 5mm bolts. I'll speed it up a little bit here. That bracket just kind of holds that wiring harness. You need to have that wire harness out of the way to remove the motor.
Next there are three T20 Torx screws; one here, one here, and then one right back in there; this one here. For the rear one I'm using an extension and a ratchet; really contorting myself in here. Fast forward here a little bit. As you can see use that ratchet and socket extension to get that rear one. Then the other two are pretty easy just with a driver and your T20 Torx bit. Once the motor's down, then you basically pull this wire harness down. Pull your motor down and then you are going to want to reach back in here, very hard for me to film, I'll show you basically how to do it later. Reach back in, press the tab on your lead, and pull it out and your motor is out.
Here's the connector. There's the tab. What you are doing is you're feeling up in there and pushing on that tab right there in order to release it. Once you have your motor out this lead right here comes from your resistor. You can see your resistor is right back here and the first thing you want to do, this is a little clip on this, just use your finger pull that clip back and disconnect that lead. Now you can also see there are a couple bolts; one back in here and one right here. They are 7/32s. There is also a bolt in behind where that lead connected in. You are going to need a driver with a 7/32 socket and I have a flexible joint on it. You can use that to get back. Push on the insulation some, the insulator, push on there and you just need to loosen this one up maybe a turn not too much.
Now the one I can't film at all, if you stick your finger back up under where you disconnected that lead, kind of in the side, you'll feel the bolt. You can see I just got my driver and my flexible joint and socket stuffed up in there and they went on to the bolt. Now here again just a couple turns maybe a half turn or one turn whatever you can get out of that one. Now you want to fully remove this one, which I guess you could call the easy one; fast forward through that. Now you reach up and in and pull the front part of it down and then pull it off those rear bolts. You can see by the way I'm struggling with it I don't think I got the hidden bolt very loose. I kind of just muscle it off there. I get it off that bolt pretty easy and then just kind of pull it off that other one and it comes down and out.
Now what I've done is I've got my adjustable wrench, I've set it to basically the head size of one of my 7/32 bolts, and I'm just going to get back in here and get on this bolt way in the back. Just make sure I loosen it up another half a turn or so. That will just make sure I can get the whole thing back together easily. Here's my original resistor and the new resistor from 1AAuto. You can see that the base of them is all the same. It's going to bolt in correctly and then the plugs are exactly the same. The receptacle for your other harness is correct as well. It's going to bolt in and plug in correctly and fix your speeds.
Maybe a little difficult to film here, but I'll do my best. We're going to put the new resistor up in here. Put it up in and we're going to tilt it to go back on to those bolts; feels like everything is all set. See there's a couple of little you just got to make sure you push it back up in there. Once you get this one tightened up, whether or not you tighten up the other one is pretty much optional because it is so hard to get to. I'll get that one and then I'm not even going to try the other one. Reconnect this harness. Take our motor and put it back up and connect that lead.
I am going to fast forward through putting the blower motor up in there. If you want to see this part of it in regular speed, check out our video for the Impala blower motor. If you've gotten it off it's pretty easy to put the blower motor up in there. Make sure you don't pinch any wires, tighten your three Torx bolts, and then connect your tube. Then put everything else back together.

Hi, I'm Mike from 1A Auto. I hope this how-to video helps you out, and next time you need parts for your vehicle, think of 1AAuto.com. Thanks.
In this video, we're going to show you how to replace the blower motor resistor on this 2003 Chevy Monte Carlo. It's the same part and similar process on these Monte Carlos from 2000 to 2005. The items you'll need for this includes a new blower motor resistor from 1AAuto.com, a T20 Torx bit, a ratchet with a swiveling head, a 7/32 inch socket, and a flashlight.
Start off by just pushing in these two tabs, you can see we're missing one, but you just push them in and pull the panel down, twist out the socket, and just pull the bulb free. Your blower motors right here, and it's held in with three T20 Torx bolts. We'll just fast-forward as Mike removes those. Now, reach back, find the harness, pull it forward, and just push the tab on the harness and disconnect it. Then, using a flat blade screwdriver, pry open on this clip, push that harness all away aside, and pull the blower motor down and out. Then just disconnect this hose, pull your harness through it, and then just remove the rest of the hose from the other end.
Your blower motor resistor is located right here, and it's held in with three screws. And you really only need to remove two of them, and then loosen up the back corner one. You can actually slide it off that, but to help get to that, you want to just push the tab on your harness and disconnect it first. Then we'll fast-forward as Mike removes and loosens those bolts. Once you're done with that, you can slide it forward, and pull it down and out.
On the left is the old blower motor resistor; on the right is the new one from 1A Auto. You can see they're identical, and they'll fit exactly the same. Push your new blower motor resistor up into place. Replace those bolts. We'll fast-forward as Mike replaces those bolts by hand and then tightens them up with his Torx bit and ratchet. Once you've tightened them up, just reconnect your harness. Then, to make it easier to put the blower motor back in, just pull this clip free right here. Now just feed your blower motor back into place.
Then replace those three T20 Torx screws. We'll fast-forward here as I put those in. I do start the first two that are easier to get to first. Put them in by hand and a few turns. Actually, I tighten them up snug with the driver, and that makes it easier to get the third one in and then tighten them all up. Reconnect the hose back, and then reconnect it to your blower motor, and put this loop back around the blower motor. Then find your harness and reconnect it. Now, put this clip back into place, put your harnesses back into the clip, and then just re-clip it. Push the bulb back into your socket, twist the socket back into this panel, feed the panel back, and then push up into place. You're all set.

Fitted the problem, but a bitch to get to under dash.
Always fast and friendly great prices i recommend you to all my friends and co workers
worked like original
Great price and it worked perfectly.
Worked great for me. Unfortunately I should have replaced the blower motor too and burnt out the new resistor. Will order again.
I am definitely way too large to be diving under the glovebox in my car but after a few existential crises, I was able to swap the part no problem. PRO TIP: I watched the accompanying video for how to swap these parts, and I found that the list of specific socket sizes needed was a little inaccurate (but close enough). If this is a repair that also causing you to buy your first set of auto tools, be sure to get an wide range of socket sizes.
Original resistor in my 2000 Monte Carlo went bad. Replaced with this one. Worked for 4 days and then not only quit working but also started smoking and nearly caught my vehicle on fire.
Cured my crazy blower in my 2000 Corvette
I followed the 1A Auto instructions on U-tube for a ez fix on my Chevy Monte Carlo SS. Love my AC again.
The products that I receive from A1 Auto are great and they fit with no problems. I watch their videos to make sure it is something that I can fix. A1 Auto is an awesome company that I recommend to everyone that ever needs parts to fix their automobile. Thank you for providing great products and customer service.
The resistor adjusts the fan speed by altering the amount of current to the blower, I would get the proper resistor if it is available. Be advised, replacing the resistor in my 99 Buick Century was a bitch as it is located right against the firewall and was VERY hard to replace. Hope yours is more accessible.
Ok, so if your blower motor only works on one or two of the motor speeds or if it went out gradually then its probably the resistor. Seldom does the motor go out. Its a fairly easy fix, but watch the video on utube it really helps.
