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.
