Hello,

I plan to replace my blower motor this weekend on my 2010 Cobalt. It's kind of noisy when I turn the heat on so I think the motor is just bad and it's cheap enough to buy a new one.

However, from the videos I've watched, it looks like I need to actually cut the existing one out since it is molded in. I thought I'd post here and see if anybody else has experience doing this and has any tips. I'm a little nervous to cut something out of my car, but I'm guessing I'll save myself a couple hundred bucks by doing so. Thanks in advance for any help or feedback!

Where did you get your replacement and do you have pics of it. Depending on which blower motor kit you have will determine how careful you have to be. I have replaced multiple molded in blower motors and there is a few different styles. On the cobalt if you get the blower motor from gm you have to reuse the old plastic housing, install the new blower into the old housing, and install a plate kit. Aftermarket ones on the other hand vary.

Here is a pdf of the gm service information procedure on replacing the blower motor with a gm blower motor kit.

Thanks! I haven't purchased a replacement yet, but I imagine as long as I have the same mounting piece I should be good to follow this procedure?

Yea if you get the kit from gm you will have to make sure you only cut in-between the ribs on the blower housing. The kit (unless there has been a update) will come with a mounting bracket that you install after transferring the new blower motor into the old plastic housing.
I use a butane soldering iron with a thin knife tip for cutting it out now but I used to use a razor blade to make a initial cut then a small and thin sawzaw blade.

Now some aftermarket blower motors will use the bracket kit from gm, and some I have seen that the housing is pre-molded in a way that doesn't use a bracket kit. On those you have to be as careful to save the old housing if you get one that's pre-molded, you only have to be careful not to mess up the hvac case. That's your call which part you get though.

I'll probably end up getting this one just because it's available in my local shop: https://www.oreillyauto.com/shop/b/l...q=blower+motor

Looks like the same configuration as the GM aftermarket part, so I assume the process should be the same.

Judging by the pictures yea it should follow normal gm replacement like I posted.
