I changed out the resistor which clips in to it's spot, no bolts or screws. Just follow the lead coming out of the front of the blower motor around the back and there it is! Unfortunately that didn't work and I had to change out the blower motor, too. And yes, as is shown on the A1 Auto video for a Chevy Cobalt, the old motor needs to be cut out with a utility knife and reinstall the new one with a metal ring and screws. It's not as bad as it sounds and it works great.

Cleaned plugged AC drain 2010 HHR
I thought I'd add to the discussion, so others might understand this task a little clearer. After reading the discussion here, and looking at the pictures, I still didn't quite get how to find the ac drain, and how to get to it to clean it.
Mine's a 2010 HHR.
I discovered I had a blocked AC drain when I started hearing sloshing sounds (actually just like a rain stick if you know what that is) whenever I made a 90 degree turn, left or right. I was lucky that no water spilled out into the cabin - got it fixed in time.
Finding the drain:
The best way I found to locate the drain is to open the hood, and stand on the driver's side of the engine. Look across the engine to the passenger side, and up against the firewall. Use a flashlight on the firewall, and you will clearly see a stub of black pipe sticking out of the firewall - you will be able to match this to pictures on other threads here (search for Evaporator Drain).
I don't have access to a lift, and there is no clearance under the car. It's possible to reach the drain from the engine compartment, but its about a 2-3 foot reach, hard to do without an extender tool. However, I discovered a little trick that worked well.
I turned the front wheels all the way to the right - clockwise. If you do this, there is enough access behind the passenger side front wheel to reach in from underneath and access the drain.
I used the 2-foot solid plastic wand adapter that comes with my shop vac. I turned the vac on and reached up to the drain opening with the wand. Once I got the vac onto the drain opening, it sucked it right open. Water started coming out and the evap successfully drained.
Afterwards, I opened the cabin filter compartment behind the glove box and found some moisture there that I dried up with a towel. I went ahead and replaced the filter since it might have mold growing.
Everything seems to be ship shape again.

Mine started to drain water throughout the blower motor, if I make a turn you can hear the water flowing between the driver and passenger side, and the blower motor makes a sound. I would hate to think it might need replacing, wouldn't know where to get the metal ring to replace the cutout area.
Looking forward to your response!
Thanks again, you Rock! 👍😎

Welcome to the forum, my fellow North Carolinian!
The drain should come out behind the front right tire. You should see a small rubber tube exiting from the lower part of the firewall. I have found that if you blast compressed air up the tube, that it will most of the time break up the clog and it will wash on down. If that doesn't work, you can back flush it with water carefully.
