I apologize for being long winded but I will explain in detail why this Corvette is driving me insane.

This car is a 1998 convertible. The power rear deck release is not working. Neither the button left to the steering wheel nor the remote will activate the actuator to open the rear deck lid. I've done some things to eleminate questions.

First I've checked the fuse for the rear hatch release. The 10amp fuse located in the fuse box on the passenger side floor, that supplies power to the switch for the rear deck, has no power going to it. Checked the fuse, the fuse is good. Even replaced it with a new one. Checked all fuses in both fuse boxes with a test light, all seem to be working fine.

The rear deck release switch left of the steering wheel serves 2 purposes. 1 it is the switch for the fog lights and 2 it is the release button for the rear deck. The electrical plug that plugs into the back of the switch has 7 wires going into it. 3 wires for the rear deck release then an empty terminal then 4 wires for the fog lights. There is power going to the switch because the the fog lights work correctly with the head lamps. The 3 wires for the release are colored as follows: an orange-main power wire, an orange wire with a black stripe and a yellow wire. The orange wire has power-checked by using a test light. The orange with a black stripe- no power. I suspect that is the wire from the fuse block. Also the trunk and the convertible top deck lid both use a micro switch to override one another. In the even trunk deck is open the micro switch will not allow you to open the convertible top hatch. If the convertible top hatch is open you cannot open the trunk. I tried all the different ways to open the rear deck and top lid, the micro switches work as designed. There are 2 wires going to the the release motor for the trunk - light blue and a black. I believe the blk is the ground and the LT blue is the power source. No power going to the LT blue wire.


Both fobs are program and work good. They lock and unlock the doors.

The other issue is when the rear deck actuator stop working so did the alarm.

Want would cause no power going to the fuse in the fuse block? I have checked all the wiring with a test light and does not appear to be any breaks. Ground wires are all intact.

Is there a module that controls the power for the alarm and the rear deck release?

I have removed the interior from this car to search this problem.

Can anyone help? Suggestions? No I don't want to burn the car.
 
I think its time you look in your FSM at the diagnostic chart for the trunk release. I know the BCM controls the trunk release and the alarm.
 
Okay

Is the BCM located on the passenger side floor or under the hood on the passenger side by the battery?
