My 08 Panel is starting to worry me. When the headlights are on, all the dash lights and the headlights flicker. I've also noticed that when I turn on the wipers to the intermittent setting the wipers operate fast for two or three swiped then go intermittent. The other day I started the vehicle with the remote start, then when I got in the ignition switch would not turn. Had to open the hood to kill the vehicle then when I got back in the car started with the key. I'm leaning toward BCM problems. Suggestions/comments anyone?

 

I hope that you are still under the bumper-to-bumper warranty. If not, I pray that you have a steady job with a good income. This does sound like the computer module (I'm a doctor with a day off from the ER, not a mechanic), and I can just imagine what replacing one might cost. Given the possible variations in models and settings, I would be scared to get this from a junk yard.

 

several weeks I had the ECM reprogrammend had 21 updates the dealer charges $92.00 my HHR is a 2006 2lt big improvement i gas mileage and better performance.

 

If it's an '08 shouldn't it still be under warranty? It could be BCM, fuse panel or connectors but it should be in GM's ball park for repairs I would think.

 

He said it's an '06 That is, if you are speaking about the post above yours.

 

Was answering the OP.... he said his is an '08.

 

Approach vehicle with caution, have stake, hammer, and holy water at the ready....just kidding a bit. Sounds like an issue with the BCM, possibly triggered by low battery voltage.
