Default Airbag sensor

Can anyone tell me if this is too corroded? A couple of the contacts hav some stuff on them though. How would I clean that? Does the outside of the box matter?

That isn't an airbag sensor. That'* a control module.

The contacts don't look too bad, but that sucker obviously lived in water from a leaky door seal for awhile. Keep in mind that we've had a member who had his airbags deploy because of this.

I suspect the water and corrosion has migrated INSIDE the box. I wouldn't bother with it.

FYI, I have the same problem on my SLE. It was that way when I bought it. I disconnected it until I get around to pulling the seat again and find a cheap replacement.

Okay, thanks! So it'* the door seal that may be causing the water under the carpet. Not a leak in the vent?

I pulled the connections from both airbags, and the control module is out. Is there still a chance of deployment?

Please cover the leaks in your other topic. I don't want to bounce back and forth to stay current on both.

With the module disconnected, the airbags cannot deply to my knowledge.

Okay sorry about that.

Back to the control module, is that the same as the SDM unit? if so, the p/n for the 97 should be 9378226, correct?

Also, how would I clean the connections on the wiring harness? Electrical contact cleaner?

Thanks

You can try spray contact cleaner in there, then inserting and removing a few times to see if that cleans it up. Badly corroded ones may need more work. If it'* a sealed plug, and is bad, it may need to be replaced (sorry - not familiar with the type from your year). If it is open in the back, the connections are generally held in with a raised part that clicks into the plastic to hold it in. Pushing in on the wire a bit, and getting something like a dental pick inside to push in on that raised part will allow it to pull out. Then you can clean it up.

Thanks again! Also had the Airbag Store quote a price of $55 shipped. Not too bad either...
