I have a 03 Monte Carlo SS and i need a blower motor resistor with climate control do I have to get one with climate control what will happen if I dont get that one?

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.

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.

Blower Motor Resistor

James

The fan works on all speeds again and wasn't to hard to put in as long as you have the right tools.

the end of the resister bent and the solder broke off

This damage could of happen in shipping. I was able to solder the end of the resister back on. I had the under dash apart so I could not wait to have a new one shipped so I was able to repair the part. So far the Blower Motor fan speeds work fine at this time. I value the videos that 1AAuto has and it is of great help to repair my vehicle.

second resistor worked

The first resistor came quickly and blew fuses when the fan was turned to high. The second resistor came and has worked as is it supposed to. Customer service was good. Delivery time each time was quick. Just wish the first resistor would have worked.

Great

Item was exactly what I needed. Contacted customer service with few questions. I got a quick respond. The website is also easy to navigate. Prices are very reasonable also compared to the big name part stores.

Excellent Replacement Part

Richard

Did the replacement and it works perfectly. Be advised though that trying to remove this part, which is located right against the firewall, behind the blower motor is very difficult. I eventually had to go to a Goodyear auto place where a much younger, shorter and more flexible fellow was able to get it out. One of the screws is almost completely hidden by the part itself and right against the firewall and you will have a tough time getting at it but it is possible. VERY awkward to get at the screws to take it out!

Fixing 2000 Chev Impala Blower Switch

Part works as described and I am a very happy customer. Thank you. ;)

hard to install

I enjoyed the video on installing the part and realize all cars have little differences but this part is hard to extract on my model. I was able to disconnect the wires and plug in this new part with no success in blower function. I'm still trouble shooting the problem . I might need to order a blower motor from you.

They sent the correct part , it snapped right in. Sales people were very helpful . I will buy from you guys again . Recommend 1Aauto to my friends.

2002 Chevy Impala blower motor resistor and air filter for cabin

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.

Replaced the resistor on Chevy Monte Carlo SS

Garry

I followed the 1A Auto instructions on U-tube for a ez fix on my Chevy Monte Carlo SS. Love my AC again.

Cured my crazy blower in my 2000 Corvette

Fire Hazard

Brock

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.

From "In Over My Head" to "Shining Moment"

Hunter

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.

Worked great

Tom

Worked great for me. Unfortunately I should have replaced the blower motor too and burnt out the new resistor. Will order again.

Don't go to ebay to save fifty cents. Use 1A.

Kevin

Great price and it worked perfectly.
