Fan motor runs sometimes??
 

Sometimes fan comes on, others time I have to pound on passenger side dash and comes on but sounds sad. Once awhile closing passenger side door turns it on. What is the issue?
Thank you.

Its a 2011 LT2 2.4L.

If it sounds sad, then I would say the fan motor is going bad.

thats my thought. Just oddpounding on the dash or door closes make it come back on.
Fans for these are expensive even from Auto zone! But last time I replaced a fan on a car it was in 2000 and was a old car.

The blower fan on the HHR's is apparently a pain to change. I believe the original is molded into the duct housing and has to be cut out.
Try the search box. There should be a few threads on this.

Can I buy a blower without the plastic ring seal and just reuse the old one?

I changed my fan in my 2006 due to the infamous 2006 model water leak issue. Luckily I purchased the car used and the original had already been cut out so replacement took all but five minute (you just have to lay in a somewhat awkward position... I found myself upside down changing it!!). Thinking I would have to cut the original one out I watched countless videos on the procedure and it really doesn't seem that bad. If you don't want to cut the motor out you essentially have to replace4 the entire HVAC system as it is assembled as a complete piece!

FIRST; take the glovebox out and inspect the cabin air filter and look for debris in the fan.

X2 what Donbrew said!! Then check for loose wires in the harness connection , here is how to do the job of replacing the blower motor, in here

And for the video how to

I replaced mine a couple of months ago. I think I bought it from CarParts.com for about $40. I found a You Tube video that had a link. I'd look it up for you but somebody broke into my house and took my laptop among other things.
