Sunday we took the Vette to a pool party about 35 miles from home, mostly interstate highway. My Wife likes to drive with lights on for safety but I like the looks of the car car with the lights down. I turned on the running lights and the fog lights to make her happy. After swimming and drinking for several hours(She drives home) I needed my hat. It seems that my head keeps getting larger, that must be why there is more room on top not covered with hair. My battery had died, I could not get the rear hatch to open with the drivers door switch but it did open with the switch in the console? Any ideas about that?
I noticed the light switch on the running light position does not give a warning chime. I do get a warning chime with the switch in full headlight position though, is this normal?

 

My 92 will chime if I leave either the parking lamps or fog lamps on and the key in the ingition.

If the battery dies, it's best to flatbed the car home or to the garage, remove and recharge the battery, then re-install before cranking the car.

The alternators' on these models aren't very stout to begin with and attempting to recharge the battery with the alternator while driving the car tends to overheat the alternator and encourage premature failure.

 

Thanks, too late though. I got a hot shot and drove home. Any idea about the door switch not opening the hatch but the console switch did? The door switch worked before and after.

 

The statement above doesn't make sense.
The CCM (Central Control Module) controls the chime.

The Signal to the CCM from the headlight switch is the same whether the Headlight switch is in Park or Head position. So if the chime works in Head it should also work in Park because the circuit is the same.

More likely you have a problem with the Left Hand Door Ajar switch.

If you open the driver side door do the courtesy lights come on?

The 93 has a sensor so in daylight the courtesy lights may not come on unless you cover the ambient sensor.

Another way to tell if the switch works is to turn the ignition key to run and open the driver side door. The Door Ajar indicator on the Driver Information Center should come on. You can also verify the passenger side switch works by doing the same test.

If it doesn't the Door Ajar Switch is sticking or bad. The switch is on the back side of the door. You could spray some silicone or WD40 on it and see if that fixes the problem.

If the Door Ajar Switch is sticking or bad that would explain why the Hatch Release Button on the driver side doesn't work. When the door is open, the switch closes which completes the path to ground so the the Hatch Release Relay is energized.

When you use the Console button, it goes thru a different circuit which requires for an Auto trans. the shifter must be in Park or Neutral. For a Manual trans. the parking brake must be on.

That's about the strangest advice I've ever read here. Why would you need to flatbed a car anywhere just for a dead battery? Why would you need to remove the battery from the car to recharge it? You could have recharged the battery at the pool party residence, AND you can leave the battery in the car AND leave the battery cables connected, but also remember to turn off the running lights while charging. It is perfectly safe to charge your car battery with the battery cables connected.

 

The battery voltage had probably dipped to the point where it was on the ragged edge of being able to furnish enough current to operate the hatch release solenoid. There is probably slightly less resistance in the circuit from the console switch than in the circuit from the door switch. If it all works normally now, I'd suggest you forget about this one-time anomaly.

Be well,

Thanks for all the replies.
The drivers door ajar switch does work correctly. The headlight switch only chimes on full headlights, NOT running lights. While sitting in the car with the door open and the headlights on I hear the chime, when I change to running lights the chime stops.
Yes both hatch switch's work, I just was wondering if there are different current paths/relays used between the door switch and the console switch.

 

The only thing I can think of is when in Park position, the parking lamps are not working which would point to a bad Headlight Switch. Verify the running lights are coming on when in the Park position.

If you gain access to the Headlight switch connector C1 there is a Brown wire which should have 12 volts on it when the Healight Switch is in Park or Head position. I think you will find no 12 volts when in Park position.

 

Could it depend on whether or not the headlight doors are open?

 

No the headlight door position doesn't matter.

There is a signal called Lights ON. When the Headlight Switch is in Park or Head position. If there is No key in the ignition, the CCM will activate the chime.

As I mentioned, verify the running lights work and if they don't verify the 15 amp Tail Fuse located on the passenger side of the dash is good.

 

OK, thanks. I'll check it out tonight.

 

I checked last night when I got home. It seems I have an intermittent problem with the chime. I opened the door and the interior lights came on(door ajar switch OK). When I turned the running lights on I heard 1chime. I sat there and turned them on and off a few times and got 1 chime sometimes and continuous chimes sometimes.

 

The Chime module is probably bad.

You can contact Jason @ Vette2Vette and see if he has a used one. He's a forum sponsor. 1 815 673-6200.

The module is located behind the Driver Information Center. The top of the dash needs to be removed to get to it.

The module has a 4 wire connector going to it.

Pin A is a Orange wire and is 12 volts
Pin B is a Purple/White wire and is Chime 2
Pin C is a Dark Blue/White wire and is Chime 1
Pin D is a Black/White wire and is ground

Chime 1 sounds for Fasten Seat Belt
Chime 2 sounds when you leave the key in the ignition
and the ignition is off and the the driver side door is opened.
Chime 3 sounds when the headlight switch is in Head or Park and no key is in the ignition. (chime 3 is a combination of chime 1 and chime 2).


Here's a thread about the chime module for a 95.

Thanks for the info. I have had the dash off to get to the PKE module, it's just under the chime module. The chime module sticks to the PKE with velcro. I bought a PKE module for the car but that was not the problem, someone had hacked into the wiring to install an aftermarket alarm and cut 2 wires for the door locks. I still have the PKE box. I followed the flow chart in the FSM and it ended with replace the PKE box. That was a lesson learned there, always check everything before opening the wallet.
