btw, your airbag light may be on because you had the seat unplug when the battery was connected (happened to me once). it take a durametric tool to reset it. my shop did it for free, but the dealer will probably charge you.

I wish that I had better news but I don't...after I THOUGHT I had everything fixed (except the airbag light staying on), it rained again yesterday and I got more water on the floorboard (including the immobilizer unit). Needless to say, now the car won't start at all. I tried to dry the board like last time but it didn't help. I was going to take the battery loose to see if I could "reset" the system but like yours the trunk and hood won't open. With a fully charged new battery, I have no idea how to get the hood to open????? I also noticed that the windows won't work (up or down). This is more complex than what I just went through with the first time the box got wet....smh. I have really tried but I am convinced that I need to get it running and then get to running.
