Sorry if I'm beating an old dog with this thread but, I have a service call lined up for Monday morning regarding my HHR's audio system.

Intermittantly, I get a low "whoomp" sound when I start my stereo system. (Sometimes this begins with the system crackling, followed by the initial "whoomp".) It usually occurs when I'm listening to the radio. Then, when I push channel selections, I can hear the low-level "whoomp" each time I depress a button. The volume is also effected by this. In order to get this to go away, I have to press the power button off and on - sometimes up to three or four times - to return it to normal.

Naturally, when I called the local Chevy dealer about this, they had never heard of such a thing. Rather than go in unarmed, I thought I'd pick your collective brains on this one and hopefully avoid having my vehicle disemboweled.

I'd appreciate any information you can provided.

Thanks in advance...

This sounds like the infamous audio system crack or radio pop problem.

There is a TSB for it. See the description in this thread: https://www.chevyhhr.net/forums/problems-service-repairs-42/old-recall-tsb-number-post-1919/

There are some threads in this forum about it. Do a search for crack.

One more thing, Black Rose. How does one access the TSB data? It appears that it's only accessible by authorized technicians or dealerships.

Thanks.

You can't access TSB's without a subscription anymore. sorry

Thanks, Mike. I'm hoping that the dealership has access. One never knows.
