Please do keep us posted on your progress. Most of us do not have your courage. It would be interesting to know what you have to disassemble, clean, and/or replace to get the car running reliably.
Water is easily ingested into the engine if you try to drive through a flooded street. I really believe my worst case scenario with this car would be if I end up having to replace the bcm...

Car looks really nice from the pictures you posted and I know you'll work out the issues quickly. Keep us posted!


Also, there is no reason for folks to fight about this or that on these forums. Some folks dicks grow to **** star status behind a keyboard and its really not worth the time and energy to argue on a Internet forum.
Well, you started out as a class act, but finished poorly. Some should quit while there're ahead. I'm into building people up.

As for the price, you can buy a light flooded car like this one for less than half of the book value.
Your instinct was right on that guy. Look at his other posts. He never, ever, has anything useful to say. On the contrary, his posts always try to belittle someone for whatever decision they may have made. He offers no help, no advice, just insults. I don't see his posts anymore as I put him on my ignore list but I see them if someone quotes them. A broken record he is. I hope he has someone at home that loves him cause he's made no friends here.

Back on topic -
I think it would be a great investment for you to get a scanner for this car with the GM specific codes. I have HP Tuners that does a great job scanning - the scanning only option isn't too expensive on their website. Only downside is HP Tuners won't read BCM codes and you may need to read those someday.

Perhaps someone will chime in with a good BCM code reader? I'd be interested. You can always get a Tech II but they aren't cheap even on ebay.

I had odd electrical problems with a truck I had - turns out the windshield was leaking on the fuse box. It looked fine to look at but when I unbolted it from the firewall it was corroded behind. I cleaned it and had years of trouble free service thereafter. I would suggest that you remove the fusebox in the passenger footboard and see what's behind it.

if you have access to some diagnostic tools it will make your life easier, if not you are going to have to hunt and peck. since the car runs (amazing) I would pull the seats and carpet out. look at the fuse boxes and any module that may have been submerged. sometimes just letting the stuff dry out will allow everything to start working, but the longer the stuff remains energized while wet the more damage can occur. get yourself some battery terminal cleaner to dissolve rust and compressed air to dry stuff out. while the carpet is out let it dry out so you don't end up having mold problems in the car. don't forget there are 2 modules inside the passenger front fender liner, 1 is the computer to the car.

I have pulled the seats and carpet already. The seats are in nice shape and the carpet dried out completely today. I bought some industrial mold killer and soaked the padding really good. After it drys out I'm hoping there will be no moldy smell. If it still smells after that I will remove the padding from the carpet and replace it with dynamat.

Don't laugh, try Fabreze on the carpet. It kills the smell of dried milk in a car, so it may solve the smell problem.

Sorry if I came across as a nay slayer? That was not my intention.
I have dealt with a couple low flood fresh water salvage cars and both were a real challenge.
I ended up with wicking problem which over time caused the wiring to build resistance which messed up both the high and low speed can bus lines. I ended up having to replace everything.
I hope you don't have that kind of luck.
you are in a situation in which you can learn a great deal about how the vette works.
you can do it...you may learn a few new cuss words in the process, but in the end it will be worth it.

Ok, now I get it. I'm amazed the engine is not damaged, since water is not compressible. I didn't even think about water getting sucked into the intake. I thought the car just sat in water. Well, it looks like you will have a nice car after you get the electrical problems fixed.

Good luck, and keep us posted!

That is not exactly true. My 96 race car had a clear car fax report yet I had a Georgia salvage certificate for it. If a persons car gets totaled and the owner buys the car back from the insurance company then a salvage never gets reported, not even an accident gets reported to Carfax. You have to know what you are looking at, not trusting what a computer print out tells you. Second bearings and all etc are sealed, it does not matter if they were under water, same with most of the electrical connections, they are waterproof right from GM. The only issues I could see with a fresh water flood that could cause his issue would be the seat modules and the BCM. Otherwise he will have the same Corvette that everyone else has, just didn't pay as much.
Now yes some flood cars can get expensive, if it was a salt water flood and it has been sitting for awhile than I would probably write that one off, but fresh water is completely different and same with a salt flood that was immediately washed down.

Thought I would give an update on the car. I didn't have any luck cleaning the bcm, so I am going to order one this week. I figured even if its not the problem, it would be good to have one as a spare since it did get wet

While the carpet is drying out,I went ahead and ordered some dynamat. I put the drivers seat back in the car and have been driving it around to see if any other bugs would show up.

The car runs and drives like a dream, but I also discovered since the doors quit working, the electric top and fuel door quit working too. So, I am hoping it is all tied in with the bcm.

I bet the stuck fuel door is a rusted spring, easy fix. Search it for remedy and Picts.

The fuel door opens easily with the manual release. There is no rust on the spring.

Hard to tell from the pics, but it seems water was 1/2 way up those fuse panels.

If I was you I'd unbolt them and clean the back side of them very carefully to get rid of corrosion...I am speaking from experience here with my truck, the backside had corrosion and I cleaned it and got years of service out of the truck with no problems.

You have nothing to lose but your time...

I suspect one of those relays is for the power windows (but don't quote me, I might be wrong)...if the windows don't work the power top won't work either. You have to index the windows for the top to work, and if the windows don't work, you can't index them so top won't work.

I think there are also door control units in each door, you should probably pull the door panels and speakers and look around in there for corrosion.

Please keep us posted, it's fun for us (not for you I bet) to follow you on your journey.

Here are a few pics of the drivers side seat area. You can see the water line here. I have pulled and cleaned all electrical components in the pass side floor already. Both doors and windows were working on the car on the first test drive, then next thing I know they both quit working at the same time. That is the reason I think it has something to do with the bcm.

I agree. I'd take all that apart under te pass side floor and check everything. You may find rust. Sometimes tightening bolts on connections helps make a better contact. Everything is replaceable and good for you for taking that on. You'll get it. I have to ask. How much did you pay for it? Good pics. I've never seen a flood car before. I think I'd take that on. Trace one circuit at a time. Perhaps you'll find one main problem spot doing it that way. I want to follow your progress too!

I'm in the process of replacing my BCM after passenger side flooded after a hard rain. BCM would be my focus.
