What would cause this problem I have checked the fuse and appears to be alright, What else might Cause no power to The System

 

What exactly do you mean?

 

If you mean the fan check the resister

 

Welcome to the site.

A little more detail would help. Like exactly "what" is not working: fan, controls ?
Also, which fuse did you check ? Saying it "appears to be alright", is kind of vague. Did you test it with a multimeter or test light ?

FWIW. The owners manual lists more than 1 fuse for the system. In fact, it shows 4 fuses and 2 relays that are possibly part of the AC/climate control wiring. (at least it shows that many in my 2010 owners manual )

And, I'm guessing you realize there are 2 fuse centers in a HHR. One under hood and one in the passenger side inner kick panel.

 

More details definitely needed - op was the equivalent to "I got a problem - how do I fix it".

 

I have a similar problem. My climate controls don't work but my fan does. I have no lights in the climate controls my passenger air bag light doesn't come on and my steering wheel controls don't work. Any help would be greatly appreciated

 

Best to always state car info(year and model) when seeking help.

Based on the items listed not working, check the ground connection at the left side of the dash.
The HHR schematic shows that to be the ground point for the steering wheel controls, passenger airbag light and a few others.

 

Playing around with screen capture.

 

Does the horn work?

Of course, it would be useful to explore exactly what happened immediately before the symptoms appeared.

Did somebody work on the car.
Did you drive over a bad bump.
etc.
