This may be a stupid question to ask...PLS forgive me Can someone tell me where the rear decklid ajar switch is located? I can't seem to find it, and I am pretty sure the "DOOR AJAR" light that is always lit is comming from the rear deck lid. I say this because I muct open the engine compartment via a screwdriver (previous owner had destroyed the lock) and had been driven around with the lid bouncing for a year or so. I removed the destroyed lock and it now latches firmley. Just waiting on the replacement lock to arrive. So I would like a "head start" on the ajar switch thanks for all the help! BTW 87 notchback 2.5L..

The ajar switch is located in part of the lock assm. In the plastic part where it meets the metal piece on the body that it shuts around.
The switch also operates the rear cargo lamp if you have one. It is a small black switch that you can operate with you finger and it's made of plastic (black). It is small and I believe faces the passengers side of the vehicle. When you push it up, the ajar light should go out. Doors closed remember. Good luck!

That's not where mine is. Its a little push button type thing(like what controls your dome light when you open your door). I cant remember exactly where it was but it definately was'nt part of the lock. Atleast that's what I adjusted to get my AJAR light to turn off. Not trying to say your wrong GTDude 'cause everything you've givin' me advice on so far has been right, Im just curious now.

my 85 Gt had a seperate door style push-in switch located on the left side of the engine compartment, but my 86.5 Gt has it integrated into the trunk release mechanism.

Well, now I'm confused. Some of the service manuals don't say where the switch is and some say it's like the door ajar switch on the body below the trunk lid.
I do remember now why I thought it was on the lock assm. It was an 88 model which the book doesn't show where it is. I was at a car show...my first...and an old timer Fiero guy showed me that by inserting a toothpick in the lock mechanism that I could keep the trunk light from burning during judging.
I think they must make two diff kinds, my guess is pre 87 and post 87, but I could be mistaken again........LOL. If you don't see a switch on the body.....it must be on the lock. Best I can do..........Thanks for pointing this out BTW! NOBODY is ever always right.....LOL...especially me. Good luck!

Just like with certain model years, 86+ they started integrating the door ajar switches into the decklid and doors. The gas tanks got bigger, the windshield washer reservoir was enlarged, 87+ the plenum was engraved, headlight motors changed, etc etc.

I do see the black switch on the decklid lock assembly.......Phil was right and mines a 87 notchback 2.5l so as far as i can tell it apears to be ok.....not sure how to test it....the door switches apear to work as the dome lights come on when the door is open....again not sure how ta test if they work right when they are closed....but the dome lights do go out..so i believe they are working...that leaves the forward compartment....and not sure how ta test it either...but pushing the switch down does not make the ajar light go out. I also discovered that there is a place for a light in that compartment...I plugged it in...but the light does not work...also discovered the previous owner cut the wires for the head light motors....when touched to ground they jus run.....seems like aomething else ta fix but least the motors run....thanks for the help and any suggestions will be appreciated greatly
