Check the passenger footwell. The A/C drain is notorious for backing up and leaking all over the ECM in the footwell.

Next I would check the battery, have it tested. Electronics are very flaky in the C5 if the battery is on it's last legs.

Good luck

What's the trick to checking the A/C drain vent and cleaning it? Is it easy to get to?

By the way, it's 15 volts, not amps. Besides the above, make sure all the grounds are clean and tight. Did it stay that way, or is it sometimes ok?

Read Bill Curlee's Ignition switch fix.

http://forums.corvetteforum.com/show...ion+switch+fix

Do the easy stuff first though, like checking the battery and battery terminals,grounds, etc.

Also check the wire in the door that is known to short out.
See post #316 on page 16 for pictures.

Man, that is going to be tough to pin down if it comes and goes. How did it look around the passenger footwell? Damp or corroded? Did it happen during any certain sequence of events? WOT, idle, anything unusual after it disappeared? Any codes that would explain what happened?

I had that happen once, very common. Check the wires in the accordian tube for one to be exposed like in the picture below. If you just grab the tube and at least shake it, all those problems will go away. The fix is to get in there and either tape the exposed wire or paint it with some liquid electrical tape, which is what I did.

See post #3 in Bill Curlee's leak check thread http://forums.corvetteforum.com/show...03&postcount=3

Fortunately I had read Bill's thread when the dreaded A/C drain leaked in my car 2 sumers ago. I knew immediately what it was and was able to dry everything out without any lasting effects.

There's no real secret to getting the tube off... it's a PITA, be prepared for some scrapes on your arm, and make sure the engine is cool!

Sounds exactly like a wet Body Control Module (BCM) If the problem persist, the BCM can get corroded and you will have ghost problems even when its dry. Ask me how I know!

Fix the leak, remove and dry out the carpet, dry the BCM. You should be good to go. Remember to clear all of those old codes!

Here is the cause of HVAC air box floods!





It lives on the passengers fire wall straight back from the back of the head:





If you have headers, the rubber elbow is a BITCH to and get off. Its a top only access unless you remove the headers.

I cut the crimp off mine and it works well.
