I have an 02 vert, a recent storm put about 10 inches into the car. I was able to move the car without starting it, removing all the water, seats, plastics, carpet. Its garaged with dehumidifier running inside the car with the top down. Car was never started, no water made it into the oil nor the engine. Also removed the intake which was also dry. No comprehensive INS. Recently moved and had no idea i was now in a flood area. What should I expect to replace? Need some help, thanks guys.

First off, was the flood salt water or fresh water?

If it was salt, you may be in deep doo dooo.

If it was fresh water, pull the dip stick and make sure the oil you see isn't milky chocolate looking. If it look OK, still pull the spark plugs and to allow any water in the cylinders to dry. However, I would not expect any water there if the oil looks OK. With that done, you should now inspect the body control module in the floor board of the passenger dept. If the BCM got wet, you again may be in for future problems. and likely it'll at least need replaced along with it's wiring harness. Evidence flooding there will show as green mold inside BCM.. If it's clean, you may be good to go. Now turn the key on ( don't try to start it yet) and attempt to read the OBDII codes using the DIC. (there are posts here telling you how to do this) Now see if the radio, power seats door locks etc work, if they do, you're looking pretty good.
Reinstall the plugs and attempt to start it if all these steps have checked out OK.
Shut the engine off and recheck the oil.
Start it again and let it idle for a few minutes then recheck the oil one more time.
Most of the computers under the hood are sealed, but the wiring harnesses are not.
Water in side the engine is a disaster, if you try to run it. It will destroy the engine post haste.
Ten inches of water is a marginal amount that may not have gotten into the BCM or engine etc.

Good luck

The computer and fuse box inside the passenger side foot well is probably toast. When Irene came thru here 2 years ago the insurance company totaled my '01. I had water up to the seat cushion. Local restorer offered to try and bring it back for about $4 - 5 grand, this included new carpet, computer, seat cushions, spraying all the connectors with silicon etc.
I ended up taking the insurance settlement rather than worry about future electrical problems.
Good Luck, sorry to hear about it.

Another area of concern could be the transmission if the water got up to the vent slots.

water was fresh, engine and oil are ok. From looks of the computer module and fuse box they appeared to get water about half way up them. vent area in car appears to be high and dry as of now. Due to only having collision and liability no Comprehensive (horrible lesson learned) I'm gonna have to do my best to get her back running.

So far BCM... Should i pull it now and attempt to clean it?

Thanks

Phanni

Cleaning the BCM would be difficult.. They are programmed for the individual options on the car, thus buying one that matches or reprogramming a used one would be needed. Someone with a TECH II would need to do this programming for you.

Marc at VettNets (or another recycler)might have a matching BCM

I assume it was parked in your garage (RIGHT), maybe home owners insurance will cover it.

There used to be a lot of vette dealers and techs in the Lakewood area, maybe you can get one of them to test it after you pull it. They can also give you an idea on replacement costs, I've seen used ones going for anywhere for $400 to $900.

I can only hope your situation isn't a death sentence. But your not too far away. And if you would like to understand how your problem is I'd call Jim S at County Corvette, @ 610-696-7888 tell them your from the forum and my name is Jim Ward. These guys can do anything. They have done work on all but one of my corvettes for 20 + years and I can assure you it's Well Worth the time and the call, as you'll feel a hell of a lot better after talking with Jim S. They are truly a five star Corvette shop. You just can't replace talent & skill.

quick update, vette starts and there are no engine issues. Message "Service Column Lock" appears. Done some research but it appears that kit was only good for years to 01, i have an 02. Should i attempt it with the kit? Or is the computer to far gone already?

Phanni

That's great news.

There is a possibility that your battery is just weak giving your Column lock error. I suggest putting a charger on the battery and see if that problem goes away over night. Did you pull the codes to see if anything else has shown up? I'd put a CLB in regardless, history shows it's the prudent thing to do.

Phanni

That is good advice.

tacman

What's your insurance company say?

killain

I agree a 100%, but I would disconnect your battery and charge it till it a good 12.5 volt, full capacity, reconnect and state it up and then pull any codes. That way your working with a good constant 12 volts to read from. I'd do the CLB no matter what, it's well worth the effort. Good luck !

He said he didn't have comprehensive insurance.

Pulled the codes here the ones i got that are of importance, checked before most of codes were L/R seat module and also Seat control module.
