#29 of 88 Re: Electrical Problems, door switches and gauges [comanche1] by bolivar May 27, 2008 (7:27 pm)
Replying to: comanche1 (May 27, 2008 12:34 pm) Well, the first thing I would do is have the battery tested. Not just check the voltage, but a 'load' test.   When the battery starts to go bad, cars loaded with electronics sometime show multiple strange displays, just like you said you saw. Low voltage makes the sensors start to display strange things.

Replying to: dave157 (Jan 07, 2008 12:02 pm) Possibly could be the Vats system(vehicle anti theft system),I had this problem. Check your ign. key's chip, I used my new key-solved the problem. When this happens usually 10 minutes later vats will reset allowing car to be started. You can purchase a vats bypass kit from Corvette Central,Mid America and others,even on Ebay. Or a good mechanic can wire in a resistor the same as in your key into the wire in your steering column. But then your alarm system is dead. Good luck.
#31 of 88 92 Corvette Electrical issues by las091964 Sep 29, 2008 (5:51 am)
I have a 92 corvette that has me stumped. When I turn on various accessories such as the windshield wipers or AC they will not shut off without turning the car off. I am also having a problem with the door ajar light coming on intermittently while I'm driving. These may not be related but can anyone point me in the right direction to troubleshoot this?

Replying to: las091964 (Sep 29, 2008 5:51 am) Door ajar is probably just a switch, on either of the doors. Switches in the old days were in the door jam at the front of the door. Newer cars have switches inside the door panels, on the locking mechanism, sensing when the door is closed. You have to take a door panel off to get to these. Even newer cars may also get one of the 'computers' involved, because they dim the lights down when a door is closed, engage the security system, autolock the doors, etc, etc, etc. But it's probably just a switch going bad on needing cleaned up with electric cleaner, etc.   For these kinds of problems, you probably need a Factory Service Manual. Chiltons will not get it done. Check on ebay, many used manuals are sold there. Or www.helmsinc.com is the publisher of factory manuals, and you can order from there.   The other problem - wow. So you start the car, something is NOT on, and you turn it on, and it will then not shut off???? Relays are involved in lots of things, but I don't see that multiple relays would fail at the same time. Even if controlled by a relay, different accessories should have their own relay.   Unless - has this car had a significant electrical problem in the past? Such as a big short to an accessory outlet? Some other electrical component that shorted out? If so, then wires inside wiring packages could have melted into one another, causing all kinds of cross-wiring across unrelated circuits.   Also, has someone put either a remote start or security system into the car? Or an aftermarket stereo? These require cutting into who knows what, and when they start to fail, and they will fail, they cause all kinds of strange problems.

Replying to: bolivar (Sep 29, 2008 3:34 pm) Thanks for the info:   The Door ajar makes sense, the actuators were replaced recently and I could see where the mechanic did not put everything back in place I will look into that. I already own a Factory Service Manual so I will get into that book and see what it says.   When I bought this car it had an upgraded stereo that is probably what's causing the issue I will take it to an electronics person and try to narrow it down.   Again thanks for the info.
#34 of 88 Jump Start Error by toml98 Oct 12, 2008 (11:02 am)
Wanted to take 91 out yesterday but the battery was too low to start. Tried to jump off my Silverado, hooked up to the truck then the Vette, By mistake I reversed the connections on the Vette, I realized my mistake almost immediately and disconnected. The truck is fine but the Vette is electrically dead. Must be a fusible link somewhere. Has anyone made the same stupid mistake or have any ideas?   Thanks
#35 of 88 Electrical Problem - Signal Switch by eloturco Oct 16, 2008 (7:44 am)
I suspect this isn't new to some.   For about two months I have been experiencing a signal switch that malfunctions when turning right or left. The switch will either not go on at all or when on will just stop working even though the switch is still in the active position.   Took it to the Chev dealer and they changed the signal multifunction switch on the steering column. Not three days later the same problem is still there.   Anyone have any answers for a now invested $551.00?
#36 of 88 Speedo flashes "SYS "then goes away then reappears? by dpardo59 Oct 20, 2008 (10:10 am)
1991 Vette coupe digital speedo just flashes "SYS" now and again. Big ZERO displayed all the time when I'm driving, will not display your driving speed. Had the heater core replaced at the Radiator shop and speedometer hasn't worked after the heater core fix. The mechanic says he only worked on the passenger side components and doesn't know why this is doing this??? Does the computer have to be reset or something ? He did say he disconnected the battery before he started the R+R. Has us buffaloed! Replaced my battery also with no change. Please help! Dennis ( retired fire fighter )
#37 of 88 Re: 2008 Z06 Electrical Drain [wfr] by rdillman Nov 10, 2008 (8:22 am)
Replying to: wfr (Jan 09, 2008 7:43 am) If you park the car for lengthly periods, put the Transmission in reverse on manual transmissions, this will slow the battery drain.

I am new to this this site and a proud owner of a 99 corvette for the past year. The last 4 months at times vehicle will not start. Power generated although will not crank to turn engine over.
