Fixing a Rust Hole?

Did that. The original problem is all fixed and has multiple layers of undercoating on it.
New problem: the interior. The airbag light is on. Disconnected the battery, pulled the airbag fuse, and attacked the airbag module that was in the flood zone when the back seat filled with water.
Top looks pristine. The bottom reveals a mess of corrosion that has jumpered connections and corroded parts on the bottom of the circuit board. So one new airbag module, check!
And found yet another rust hole. This one can't be fixed like the last. Just going to coat it with undercoating and forget about it until the summer.

I hate when water corrodes electrical stuff......
Me too. Oh well. New module ordered. Different part number, looks the same. Would be a standard GM update that means you can't get exactly what you need. Hope it works.

Make sure you disconnect the battery before you install any parts on the air bag system.

Working on air bags:
Step 1. Disconnect battery.
Step 2. Install parts.
Step 3. Triple check installation.
Step 4. Reconnect battery.
Step 5. Turn on car.
Step 6. Hope there's no step 6!

Replacement module in, and no boom so far! It did just what the service manual (the factory one that uses a tree, not that Haynes junk) said it would do for successfully re-arming.
Yes, I did duck while turning the ignition after installing the module.
Now to track down the next hole...

I had a 1981 Datsun Maxima that I patched with RTV and kept the rust at bay with some free cold galvanizing spray (it was a gray car), finally my wife wouldn't let the kids ride in it so I got rid of it in 2000. RTV can be ugly, but works great in those hard to see spots.
