Are you a current or recent car shopper who bought an EV and then installed solar – or who had solar already, making the decision to go electric easier?
Are you a recent EV buyer (past 3 months) as a result of manufacturer incentives and dealer discounts on these vehicles, including year-end deals? Were you convinced to buy an EV after finding a good end-of-year deal, or due to uncertainty around which EVs will no longer qualify for full/partial EV tax credits in 2024?

99 Grand Am Airbag system components?

My 99 Grand Am had the misfortune of getting soaked by about 10 gals of water on the pass. side floor, front & rear. Shortly thereafter, my "Airbag Status" red light went on---- I know the airbag diagnostic control module is mounted on the floor under pass. seat, and assume it is fried. However, when I removed carpet to dry, I noticed an electrical component bolted to the vertical part of the floor pan at about the middle of the door: it's 1.5" square by 1/4" thick black plastic with 4-5 black wires going in/out...(there's a similar one in same spot on driver's side).
My question is: does anyone know if this is part of SRS, and what this part does? If I'm investing $200+ for the new diag. module alone, I want replace all SRS parts that got wet to make sure it works... thanks

    Any mechanic who knows about the SRS sytem is not likely to provide any info, becuase of obvious reasons.
    The guys who work on the systems go thru a bunch of training to prevent THEM from getting hurt.
    EMT and emergency personel must go thru training to properly extract peopel in the event the airbag hasn't deployed.

    But as Opatience states, just take it to the shop. If you mess with the system and it goes off you are libel to get hurt, and on top of that pay another $1000 to get new air bags installed. Even if the air bags don't go off you can be driving down the road and an improperly installed part or connector can trigger the air bags to go off causing a wreck.

    To answer your question if the wires that go into those sensors are in a yellow jacket, or have a yellow plug on them it is part of the SRS system.

    The water might have just shorted out something and you need to change a fuse, so check that first. If that is not the case off to the dealer.

    I think what you have found is a "common ground". Rather than spot a series of grounds all over the vehicle, they get combined at one point. Chances are you've fried the SRS control box, hopefully your carpet is nice and dry so no mold starts. If your worried about the integrity of the grounds, slip some stainless serated (sawtooth) washers under the contact. In other words, go to Home Depot, remove the bolt at the ground and bolt it back together. I'm not sure if your new control will have to be programed to synch itself with the other controls. Just don't apply any voltage to any yellow connectors anywhere in the vehicle. Yellow connectors signify that the connection is to an airbag device. I think you will find every manufacturer does this. Good luck and if you have any more questions I may be able to look at the shop manuals to get you an answer.
