Default Electrical Problems

I have the manuals downloaded to my phone, but no where else so it makes investigating these things more of a challenge than it should be…

1994 corvette coupe

symptoms/issues:

-Air Bag light is on under normal circumstances, unless I start the car with the driver’s door open.

-When I shut the driver’s door, it sounds like the passenger’s door tries to lock.

-The hatch doesn’t always want to open (When it doesn’t work, I can hear a faint click when I hit the switch in the door or the console).


Initially I blamed the hatch on the door hatch switch. I took it out and cleaned the contacts as best as I could.

Then I realized that there’s a link between that and the door ajar switch and sometimes things act funny with the driver’s door, so I replaced the door ajar switch.

The air bag light has been on. But I’ve noticed that if I start the driver’s door is open the air bag light will blink a few times and then go off.

Is there a link between the driver’s door, the air bag and the hatch opening?

Have you looked to see if there's a common ground.

After reviewing the wiring diagram I see that the hatch switches complete a ground circuit.

I will check the resistance from the console hatch switch to the negative battery terminal (as a reference I will find another point to check resistance as well). The non volt meter method would be to run a test ground wire from the battery to the console switch.
