Hi folks! I've got a problem with my wife's 2007 Cobalt LS (base model, I think it's LS). A while ago the service airbag message came up on the driver display. I took it to the dealership where we bought the car (not a Chevy dealer, it was used) and they replaced the clockspring.

A few months later, the service airbag message comes up again. As the warranty is now up, I take it to the local Chevy dealership. They read the codes (charging me $80) and tell me the clockspring is bad. This time I replace it myself. I take it back (to a different dealer) to have the codes cleared and they tell me now it is the wiring or connector to the clockspring. I take the wiring all apart and find where 2 airbag wires were pinched in the tilt mechanism (likely threw the clockspring code too) and repair the wires. I take it back to the dealer again and this time they say the front airbag impact sensor is bad. I haven't replaced it yet as it is pricey ($200).

But my question is this, why can't I get a straight answer on the problem and how the heck am I supposed to test these parts? I can't find any info on trying to diagnose and repair it myself. Oh and this car has 45,000 miles on it. Something has to be wrong, NOTHING should wear out in 45,000 miles except brakes and tires.

Dealers do that all the time, I bought my own TechII since I own 4 GMs. I don't believe for one second that your front airbag sensor is bad. Just disconnect it clean the connector contacts and reconnect. OH! disconnect battery first.

That sounds easy enough... where is the front airbag sensor?

It is almost in the middle of the top radiator support bracket, engine side.

Thanks! I found it and removed it to check the wiring connections. It looks brand new! I'm gonna have to buy the cable and software to diagnose this thing.
