DIY, change the blower motor on your Chevy Impala, the model produced between 2000 and 2003. The repair might take you more than half an hour, though it is not that difficult. You will need a flat blade screwdriver, a 5 mm socket wrench, a T20 torx driver and in some cases, needle nose pliers.
In the beginning, you will have to open the front door, on the passenger’s side. The blower motor is located under the glove box, but first you will have to remove a plastic panel beneath. This panel is held by a pin and two clips, like the ones in the picture below. The clips can be undone by hand but that pin can be tricky. You might be able to remove it with a flat blade screwdriver, but if you do not succeed, you might consider using needle nose pliers.
After you get rid of that panel and you disconnect the little light bulb behind it, you should work on removing the metal bracket shown in the next image, that is held by two 5 mm bolts.
After you do it, undo the three T20 screws that secure the blower motor (like the ones in the picture below) and disconnect the electrical harness located behind.
Pull out the blower motor and install the replacement one. Plug back the electrical harness and insert the new motor in its place. After you secure it and the metal bracket, you can reinstall the plastic panel and that should be it. These are the steps you have to follow, if you wish to remove and replace the blower motor on your Chevy Impala, the model made between the years 2000 and 2003.
