Hi, I'm Don from 1A Auto. I hope this how-to video helps you out, and next time you need parts for your vehicle, think of Thanks.

In this video we're going to show you how to replace the blower motor in this 1997 Buick LeSabre. This motor fits LeSabres from '93 to '99. It also fits a whole bunch of other GM cars, the Olds 98, Pontiac Bonneville, and Cadillac DeVille. As long as it's a front drive car the procedure should be basically the same. The only tools you're going to need are a 7mm socket and ratchet, as well as a 13mm socket and ratchet.

We're going to remove two 13mm nuts that hold this bracket into place right in there on the back side: here and here. I'm using a flexible head 3/8 inch ratchet with a 13mm on it. I'm going to fast forward it. The nice thing about these two nuts is we found that once you got them loose they just came right off by hand and then you can move the bracket out of the way. You pull the bracket up and out of the way and you're going to want to locate the one, two, three, four, five screws that hold the blower fan in and those are 7 mm. Locate your tab, lift up on it, and then pull out. We're going to fast forward as we just remove those five screws. We suggest removing the four on the bottom first and then save one of the top ones for last.

Here's the old part and the new part from 1A Auto, exactly the same. We're going to need to swap over this cushion from the old one to the new one. Okay, carefully pull the cushion out of each hole, slide it down off the old blower motor, put it onto the new blower motor, and then make sure that you have it in the right position and lock it back into the mounting holes in the new blower motor.

Swap over your elbow for the drain, put your cap back on. Remember the correct position for it is that the elbow for the drain is pointing right out to the left toward the passenger side and the connection is also pointing toward the passenger side, but mostly down right into probably about the seven o'clock position as you're looking at it. Once you have it in there and all set then just start your bolts in and tighten them up. Make sure that the drain hose is pointed down so if any water gets into this housing it'll drain right out and then plug your harness back in. Then go back in with the bracket and the two 13mm nuts. We'll just speed up from here. Get the bracket into place, start the nuts on by hand, you can pretty much tighten them up finger tight and then it takes just a few turns to tighten them up with the wrench. They need to be snug, 20 to 25 foot pounds.
