Brought to you by 1AAuto.com, your source for quality replacement parts and the best service on the Internet. Hi I'm Mike from 1AAuto. 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 an AC and heater fan motor. Usually you'll start hearing the motor groan or make a higher pitched squeaking noise. That's when you know it's starting to get bad and sometimes they do just quit all together. The fan in this vehicle is actually molded into place. You do have to cut it out. The tools you'll need are a flat blade screwdriver, a utility knife, you'll need a drill with a half inch bit to drill out a couple of plastic rivets, a small socket ratchet, and eight small coarse thread bolts or screws. The lead goes in right above your passenger's feet, just use a screwdriver and press the tabs there and it comes right out. Then you get a nice sharp razor knife and you actually just cut. There's a groove all the way around the motor. You just push your razor knife right up into it.
Now I'm going to speed up the tape. Obviously you want to do this very carefully. Be very careful not to cut yourself with the razor knife. Like I said, there's a groove all the way around. Stick your razor knife up in there and just pull or push in a controlled manner and work your way all the way around the motor. There is a block in the front of the motor where the groove basically does not exist and that's the part where you try and cut into it that as much as possible and in the end probably a little piece of that will break off. The motor is held to this housing with two plastic rivets. I'm going to use the three-eighths drill. I'm going to speed up here. I just drilled those two plastic rivets. They're pretty easy. Don't use a lot of pressure; you don't want to drill too far through. Drill a little bit with the three eighths and then I actually do switch to a half-inch diameter drill bit to finish it off. Push down on the two studs where you removed the nuts and separate the plastic housing from the motor.
The old motor comes out. The new motor from 1A Auto, exactly the same as the old motor, put it obviously where the lead goes. That goes to the corresponding area on this housing. Put it down on. Speed up here again as I put those two nuts on and then tighten them up. You don't want to tighten them incredibly tight but you want them nice and firm. Now you need eight of these small coarse thread bolts. Basically you just use them. Place the rivets and molding. Fast forward here. As I just used, like I said, some small coarse thread bolts about the size of the diameter of the holes and bolt that together. You use them in place of where the rivets were, as well as you'll use a ring provided with the motor to reinstall it. Obviously we can't mold it back in so it comes with a ring. Put the ring in place and then use the small bolts to bolt it on to the plastic. You want to make sure your bolts aren't too long. You only want them to be a centimeter long, or so, or else they could interfere with the fan if they go too far through the housing.
I'm going to go through this kind of relatively fast. You've got the new motor with the ring on it. Put it up in there. Start a couple of the bolts in by hand as much as you can. Then get the two ones that are easiest to get to. Tighten them up somewhat and then you can tighten the third one that's more difficult to get to. Tighten that one up and then just reconnect the lead and you should be all set.

Blower motor

Was a little worried trying to change out the blower motor on my 2006 Saturn Ion, but it was okay. The video on your website made it easy and showed me what to do. Cut out the old motor and followed the instructions and it was a breeze. I used a mirror to see under where the motor is screwed back in. You should mention that in the video for some of your novice do it yourselfers. Thank you! I now have a quiet running blower motor!
Works perfect on 2007 Pontiac G5

The blower still makes a noise on lowest setting. Not all the time. It happens randomly. I dont know if all of them are made this way within their gears.

The part is a perfect fit. The blower motor runs very quietly and seems to be more powerful than the original. It's an easy install. Very happy with the part and the ease of service from the website. I would definitely recommend this part to anyone who needs this replaced. I recommend this company to everyone I know and spread the word about how great their service and fast shipping is.
Excellent quality parts!

Ordered this from 1A Auto, received the part 1 week sooner than expected/quoted for time. In depth video showed how to do everything from cutting out the old one to bolting in the new one with the provided metal ring for retrofit. My 2009 Chevy cobalt actually already had metal bolts where they said you had to drill out rivets & replace with some coarse thread bolts,
... the rivet wasn't actually melted so it made this even faster! 1A auto also included 6 bolts for the adapter ring which i was super happy about not having to go and find them! Also did the resistor at the same time for fan speed settings and was really quick and easy as well.
Perfect

Fan Motor

With the exception on my 2006 having a different fan housing this blower motor was very easy to install. I looked at the youtube video, decided even at 62 that I could do the job, ordered the part and now I have a fan that does not make noises when it is on. Thanks 1AAuto for your video, parts and your quick delivery. Bring on the summer. LOL

I have found the service and price that A1 auto parts offers to be at the top of the list. I saved almost 50% on my last purchase as compared to local parts houses and in some cases even more. the step by step instructions are something auto parts stores can't offer.
Thanks
The posts were a little off from center but it works well

So the posts were a little off so after a little drilling to make it fit and has worked like a champ since. The last heater kept blowing the blower resistor and this new heater fixed the issue.

Quick ordering. Great videos. Arrived in three days. Pain to remove old one but that's due to GM. Took about 45 minutes. I ended up using a hack saw blade which work better than the utility knife which I started with.
New one bolted in perfectly. Thanks for including the 6 additional screws. Took about 20 minutes. No fan noise and lots of air flow. Didn't realize just how bad the old one had become before it just quit.
Thanks A1 Auto.

At this time we do not have the dimensions of these screws. We suggest searching a affiliated dealership website parts department that has these specifications.
