Default Hatch Glass Switch Inop.

1995 Corvette. Hatch Glass will not open using driver’s side door switch or button on key fob. Want to check fuse first. Where is it located? Then go from there. Any help would be much appreciated. Thanks.

Important I believe to ask if latch release operates from console. Yes/no? AT or MT - if you have console operation I believe it safe to assume the fuse ain't bad.

Fuse is #45 - lower right in box. Bottom row next to circuit breaker stack.

Do you have the FSM?

Hey Dave, Thanks for the info. It is a 1995 Corvette with auto trans. Didn’t know it has a hatch release in the console. I will try it and see if it works. I do not own an FSM for the car.

If the switch in the console works it is probably a bad door ajar switch preventing drivers side switch from working.

With an AT the shifter must be in either PARK or NEUTRAL for operation. Maybe you need to check the Owners Manual for operation.

Do you have that?

If not it's here free from GM, you do NOT need to establish an account to acquire the Owners Manual

Hey Jim,
Thanks for the info. While sitting in the car last night engine off interior lights came on and went off several times. Bad driver’s side door ajar switch? Thanks.

My hatch stopped working. It was door switch. Check that out first. Common problem on these cars.

oh and my lights would do that too

Passenger door switch work? While the door is open, check the fuse. It says "Hatch".

Opened passenger side door only. Courtesy lights are on. Pulled hatch fuse 25 amp. Fuse looks fine.

94-96 cars didn't have passenger side hatch switches.

If you are not hearing a click, you need to check the connectors at the relay and solenoid for power. Have fun crawling back there to get to the emergency release cable.

Can you tell me where the relay and solenoid are located for the hatch glass release?

Looks like the culprit may be the driver’s side door switch. Anyone know where I can purchase one of these good quality at a good price?

The hatch switch or door ajar switch? I have not found a good aftermarket door ajar switch. They all fail in a short amount of time, like months if they even work.

Thanks, didn't know that. Cost cutting I guess. Makes faulty switch diagnosing more difficult. I use mine often when I am in the staging lanes on the passenger side and want to pop the hatch to check or fill the tires.

Slightly OT but my '93 doesn't either.
