    I have a service airbag warning flashing at me. I am guessing I knocked a wire off a sensor or something... Anyone have this happen? Where exactly are the sensors located?

    Truck is '04 2500 gmc d-max.

    9 time out of 10 on a GM truck it's the clock spring inside the steering column that fails and trips the air bag light. The clock spring winds and unwinds every time you turn the steering wheel so it's even more common on a plow truck since your constantly working the wheel, and it's usually lock to lock when plowing..especially in tight area's.

    Not an expensive repair but I'd highly recommend leaving up to the dealer to fix...you can cause more problems than you fix if your not knowledgeable on this repair procedure.

    No, the wheel position won't make a difference one the problem is there. Once the airbag monitoring system detects a problem, it will store the code and blink the air bag light randomly until it's repaired.

    I haven't seen a light or warning since last time i went plowing saturday... Seems pretty intermittent. I am thinking I possibly knocked one of the sensors down below, but not enough to completely ruin the circuit? Think that is possible?

    Sure it's possible... if you have it scanned though you'll know for sure if it's a sensor or wiring problem.

    Not on my trucks but, on my chevy cars it was always the front bumper sensor. I think $20 to replace.
