IMPORTANT ELECTRICAL INFORMATION (Long!)
#1741
Fogged/wet windows should have warned me to trouble
Owned an '01 Z06 for 18 months and it has always had dampness and water on the sills but was lucky until now, I guess. Stored the car outside a couple of weeks ago and it rained and soaked the passenger side carpet and did a BAZERKO (lights, starts but won't run, windshield wiper/washer won't stop, driver side running light won't go off, etc..). I joined this forum and have read a lot of great info. and then proceeded to dry the carpet with a box fan for 2 days and then check grounds/fuses/etc. based on what others have tried. The fan worked and I was able to start and drive the car but after learning how to use the DIC, realized I still had a lot of issues (ABS/TCS, HVAC NO COMM, RADIO NO COMM, etc.) and wipers/washers that wouldn't stop. I checked grounds and they looked good so the next step seemed to be the famed ignition switch and after two tries (too much bending of the springs the first time), the codes are all gone and the only problem is getting the windshield washer to stop so I will do another pass on the stalk to clean the contacts.
I had an appointment with the local "expert" to bring the car to him and his early assessment was a problem with mice!!! You (Bill and all the others) deserve a lot of credit for taking the time to document the fixes that work or could work but best of all, you have helped me learn how to live with this car!!! I love it and was starting to get a little aggravated and concerned about replacing parts, which not only seem hard to find, but spending money to have the dealer or so called experts charging me to try things without knowledge.
It would be great to see a trouble shooting flowchart that points to fixes to save time in finding all of this great info and pictures of what to do and once again, MANY THANKS for doing so much already!!!

C5 Ground.
I did this on my '99 FRC before I read the article.
In Florida its a problem...
So it I can say this protocol really cleans up a lot of issues.
Mine was the headlights didn't open and the turn sigs didn't operate.
What else - I don't know.
I sprayed the grounds with Corrosion X.

Here's my picture tour along the ground points. It may help someone who wants to clean them and can't find them.
It also contains a warning re. G401 and G402: big chance the studs will break off when you'll try to remove their nuts.

Fob learning Issue
#1748
My Corvette draws more than 10A. I narrowed down the problem to two circuits - fuse 6 and 25 on the passenger floor. I took the following measurements:
#25 out and #6 in - 5.1A goes down to 4.2A after 20 sec
#6 out and #25 in - 12A goes down to 9.2A after 30 sec
if both are out no current.
Please advise.

Best method would be, I think, to first clean the stud with a multitool so most of the rust will come off, then soak it with WD40, then turn the nut.

Why not try something like PB blaster thread lubricant? This seems to work much better than WD40 for penetration into the threads.

Hello everyone.
I have an issue with backlighting staying on for HUD and IPC gauge buttons which are draining the battery.
No codes or corrosion on BCM board.
Any leads?
Thank you in advance.

Lightly sand the connectors and the area around the base.
WD 40 works great.
Make sure the area is dry of oil.
Then apply a dielectric spray to the connector and the contact point ground.
CORROSION X is the absolute best.
Its what I have used for this issue.
And the problem went away.

THIS,,, is a severe case of owning and driving a C5 in the Northeast (CT) 98 Coupe. The grounds take a BEATING. When the nut was removed, it just snapped off. Thats why its very important to soak the nut in PB Blaster or WD-40 over night and carefully remove it.
As you can see,, there is RUST on the area where the eyelet would contact the the chassis making a **** POOR GROUND CONNECTION.
I,,,, Personally use a Stainless Steel Toothbrush wire brush and remove the rust off the chassis and corrosion off the eyelet.
Same for the Splice pack connection. SS Wire brush and blast it out with Brake Parts cleaner.
NASTY Splice Pack Male pins:
Wire brush makes them looks like NEW!
You will NOT be able to sand paper the splice pack female pins. WIRE BRUSH and Spray makes the job doable.
Early C5 must have had inferior chassis paint because this is my 02 ZO6 and I drive it on the same roade the same amount of time:

Thank you Bill
This is not just a great 'how-to fix' write-up. This is a study in methodical troubleshooting, how to be thorough and make a detail perfect repair, post-repair testing, and repair documentation. This one fix could be a course at MIT or any great school on those topics.
Thanks much. You set the bar very high for the rest of us.
