So I drive in to work this morning for 6am. Everything is fine. I park car, before I turned off ignition I noticed the headlights were flickering. I get out and take a look. Yes they are flickering. So I get back in, car running, and noticed that the driver window didn't return all the way up. So I turned it off. I start it back up, window will work if I use the up/down button, but will not index back up upon exit. So it looks like it going to rain so I decided to move my car under the covered area at work. I'm new on the job, so more senior employees get the covered parking. I talk a lady into letting me park in her spot. I get in car, start it up, and now my side mirrors are not where they are supposed to be. I press #2 (wife's setting) and the seat, mirrors, steering wheel all go to her setting. #1 however does nothing. So all in the span of 5 minutes, after a 20 miles drive, the headlights are flickering on idle, window won't return up, but indexes down, and #1 memory is gone. What the hell is going on? I will also add, that not a trace of any of these issues occurred before this morning.

 

Also I searched the forum and surprisingly nothing came up. I find it hard to believe that I'm the only one this has happened to.

 

Have you discounted the battery, so the computers can wind down.

I know the windows also use computer, not like olden days!

Remember you have re-index with windows, so recommend you have them in the down position.

 

I haven't done anything yet bc I'm at work. I would think a failing battery is the only thing that would cause multiple electrical issues like that all at one time. Unless somehow all three of those things all share the same ground point. I would be surprised if they do.

I bought the car 2 months ago. The battery is nice and clean, but the little date tabs were never removed, so I don't know how old the battery is. I had a battery tender on it for a complete cycle about a month ago bc I didn't like how it sort of slightly dragged on cold start up. It always started with no issue, it just wasn't quick/crisp like the vehicle I just traded in was. So I put it on the tender and it didn't really change anything. So I just chalked it up to a characteristic of the C6 Corvette. I'm going to replace the battery today and see what happens. This C6 has a short leash though with electrical BS. I had an 01 Land Rover Discovery that I fought electrical **** on for a long time and I'm not about to deal with that kind of pia bs again.

 

Well the battery can cause all kinds of headaches, my 05 the battery lasts 2 years and 6 months and than start getting slow cranks, had the electrical checked numerous time all coming back is normal.
If you don't know how old it is, I would start with fresh new battery.

Good Luck!

 

Check battery, battery connection and alternator.

 

I got major problems. So at lunch I bought a new battery. The old one actually tested good, but I noticed it was only 525cca and the spec calls for 590. So I just bought a new one to eliminate the battery. I install the battery and nothing works. Only thing that comes on is my JVC radio/touchscreen. Nothing else. Nothing on dash nothing. When I press ignition, every so often I can hear a faint crackling. My C6 is dead just like that. I’m 20 miles from home. I’m not happy.

 

new battery, connections tight and corrosion free. I just did it in the last hour. Can’t check alternator bc car is completely dead.

 

Horn works, headlights work. JVC touchscreen is on, but only the backup camera screen. I put my key fob in the slot in glove box, buttons facing right. Still nothing. I also used a load tester we had at work and my new battery is good.

 

Any updates, on what fixed your problem or still troubleshooting?

 

It’s still sitting at work. No local mechanic wants to mess with electrical problems on a Vette. The local dealer says, get this: “Chevy won’t send us the info to work on Corvettes and we don’t have a lift that lift it without doing damage to underside” WTF?. So no mechanic, no dealer, and no forum support. Which saddens me. So I decided to just go home and drink all weekend looking for my next non GM vehicle online. What a crock.

 

I think it has something to do with anti theft stuff. When I changed the battery etc, maybe something triggered something. Dunno. When I put my fob into the slot, that should have at least done something. It did nothing. The DIC doesn’t say fob not detected, so I don’t know. Since it will need to be towed somewhere, and it’s safe at work, I figured I would let it sit with a fresh battery all weekend and see what happens Monday. That way I’m not towing it twice. I have doubts though, bc my original battery tested good. I feel like if I dive in and spend all the time and find the cheap *** wire/connector/bad engineering problem, another similar thing will probably happen not long after. Been there done that. Not doing it again. I’m not worried, it was a fun Corvette Summer. Cut bait and move on.

 

`this is the under car pos lead conection. if there is trouble here or ground. you are not going anywhere.

 

I may throw my tools and my boards and my jack and my pucks and my jack stands (Ha) in the 4runner and go mess with it later on today after the sun stops blazing. I just don't think it's related to a ground or to the starter connections/solenoid. There has been zero intermittent issues of any of this stuff pror to this occuring. For it all to just go dead pretty instantly isn't consistent with bad grounds or connections. In my experience those things usually come and go, until finally it just goes. I haven't done any type of electrical work prior to this. I have an Autel diagnostic tool and it wouldn't even connect to the car. I checked both fuse boxes and surprisingly, none are blown. I know where all the grounds are, several good videos on that. The grounds I can access from the top all "appear" tight and corrosion free. My instinct says it's something with the battery install, anti theft, key fob, weird fuse thing, or steering column lock stuff. Baffled why backup camera screen is on, (it's not in reverse), the headlights, horn, rear hatch latch motor, and rearview mirror lights all work fine, but dash and most everything else is just dead. I was sure it was a fuse. It isn't. I'll update tonight if I end up going.

 

Ok, so the car is alive. I didn't go work on it yesterday. So when my wife dropped me off this morning, don't know why I thought of this, but I grabbed her key fob out of curiosity. Well well well, the car acted like nothing ever happened. I walked up, immediately noticed the red light on inside the door on, opened the door, got in, and it started right up and moved into memory #2 seat, wheel, mirror position. WTF? So I turned everything off, put her fob on my office desk, grabbed my fob, went out to the car. Nothing. Just like before, had use key to open hatch, pull cable etc to get in. Doesn't say no fob detected or anything. So once again I put my fob into the glove box slot, buttons facing to the right, and nothing. So whatever. I drive it home with her key fob. I change the battery on my fob, and the car works just fine. Like nothing ever happened. So apparently, last week, all at the same time, my car battery weakened enough to screw with the car and my key fob battery died. Hummmm.......

Anyhow, I put another brand new fob battery in the center console just in case this nonsense ever happens again. I don't understand why the slot didn't work. About two weeks ago I showed my wife how to use the slot, in case she ever needed to. It worked fine then. In fact when I reprogrammed both fobs about a month ago it worked just fine. I've seen videos of people using the slot without a battery even being in the fob. So I don't understand what went on with my car, but everything appears to working ok as of now.

Car defineltly starts much quicker and crisper. It doesn't have that little drag that it had before the new battery and I installed my new ignition switch today. So I guess the car is better off now than it was before this episode. It was nice to actually drive it today.

 

Glad you have a happy ending, and keep spare battery incase of emergency's.

You might want to buy 3 FOB, Amazon sells them at a good price, program it and remove the battery and keep it in the car for next time something like this happens again, hoping it won't, better safe then sorry.

Since you already know how program them, small investment, might pay off big time.

 

It didn’t last long. See my thread in the general discussion how it locked me out this morning.
