If it works intermittently, you probably have a damaged wire -- my guess would be where the wiring harness goes to the trunk lid. The constant motion of use can damage the wires internally. They still look ok on the outside usually, you'll have to check them electrically (with a meter or test light) The other possibility is damage to the harness that goes to the latch from something moving in the trunk and hitting it. Good luck.

Minor corrosion and wear occurs in the plug at the actuator. The pins or female connectors may be worn and loose. There are four holes in the receiving plug on the actuator. Easy to probe with test light (not to deep or you'll ground out on the motor housing and blow the fuse). Probe the 3 wires with test light, ground clip end on test light. Activate (toggle (push) up and release for each test) finger switch on the trunk lid lock. If no power probe wire side of plug (back). Stick 3 straight pins or paper clips alog side the wires to contact the female terminals. If still no power, work your way down the harness up to the trunk lid switch. Another quickie: Push the deck lid lock finger switch up, with the activator motor plug exposed, grab the plug and shake it. If you can get it to function and fail, on failure grab each wire with a needle nose plier, push and pull each wire starting with the one toward the front of the vehicle. If you're successful, try bending the male terminal or slightly closing the female terminal. Finess is necessary here.

ON a 94 Caddy power trunk lid. I had to disconnected the fuse.and use the key to the trunk,to open it.the reason being,it was drawing power from the battery.


The switch that shuts the motor off when it pulls the trunk lid down is not working. That power actuator is the same for most GM cars and is readily available at a dealer.

Trunk won't open


The actuator may sound as though it is working but the latch could be damaged or misaligned. Also, the actuator could be too weak to operate the latch. If it is necessary to replace the actuator, your Camry is old enough to make a junkyard a likely source.

My trunk won't open, I have tried my trunk button and the key won't work, it worked fine a few hours, but even when i try to do it manually it won't open. Also I would look in and try the...


There are 3 phases to fixing your car's trunk lid release problem.

Phase 1: First check the fuse - once you know that's OK, then proceed to phase 2 (below).
The fuse for the trunk lock is
the bcm (pwr) 15A fuse in the instrument panel fuse box (behind panel at drivers right foot)

Check that fuse, as it is the power supply for the button on the dash that sends power to the actuator in the trunk.

Phase 2: Get the trunk open (without taking it to the dealership).
If you have remote keyless entry to the trunk, you could try that - but with the actuator
dead/dying, it shouldn't work.

Here are a couple of ideas to try to enter trunk while (a) actuator isn't working, and (b) all
valet lockout features (designed to deny valets access to the trunk) are in the "Lock" position:

There is the lock cylinder, which you stated is not functioning - put the key in, and it doesn't
turn. Just to be sure, consider: lubricate key with Graphite lock-type lubricant, and retry.

The trunk has 2 valet safetys...the locking rear seats which require access to the trunk to unlock, and then there is a valet switch in the trunk that locks the button on the dash from working to keep valet parking attendants out of the trunk. That may be in the lock position.

You can try accessing the center area of the fold down rear seat and see if you can unhinge the rear seat from there. Maybe reach in with your hand, or an extension-type tool.

there may be a way to fold the hinge away from the seat back so it can be removed from the hinge and give you access to the safety latch in the trunk and open it that way (white handle in trunk).
The white-handled safety latch release is desiged to prevent accidentally trapping children, and
if you can pull it with your extending-type or grasping-type tool, the trunk will open whether or
not the actuator motor is working.

Phase 3: Replace the Problem part.

Your failed part may be either (1) Trunk Release Relay, or (2) Trunk Lock Release Switch

My Satrun ION manual doesn't cover either of these parts, and the online parts houses, e.g.
http://www.rockauto.com/catalog/x,carcode,1431624,pgname,Electrical-Switch%2B%2526%252338%253B%2BRelay,a,search.yahoo.com%2BSearch%2Bfor%2B2004%2BSATURN
fail to provide instructions. One of those times a mechanic has to t=rely on his/her native
handiness and/or experience.
To identify which of these parts is bad, locae the Trunk Release Relay (call your dealer parts
dept. for helpful tips on finding it), then operate the dashboard trunk release button with your
ear close tothe relay - if it makes a noise, the problem is the Trunk Lock Release Switch in
the trunk lid, otherwise its the relay.

Trunk will not close all the way down on my 1992 buick riveria


These units have a trunk actuator pull down motor that after you close the trunk the actuator pulls the trunk lid down to the closed position,These units failed quite often 90 % of the time the only problem was the $20.00 switch that's sits on to of the actuator, not the $300.00 actuator assembly. this part is easy to replace it has only one screw holding it, and the switch sits right on to of the actuator.

Trunk pull down motor does not work. how do i replace it?


Hello: If the pull down motor case isn't broken, then before replacing the motor I would replace the pull down motor switch, it is black and on the left side of the motor, take note of how the switch is mounted on the motor (the position of the tang on the switch in relation to the actuator. The pull down switch is held on with one screw.

It wont latch on n shut.


Good afternoon! The cadillac you have uses two switches to control the automatic pull down feature. If the trunk was unintentionally slammed it can break one or both switches. The switch in the decklid (or trunk door)controls the light in trunk and is also a input to the lower switch at motor to signal trunk closing. Even though the light in trunk works this does not mean close signal portion is ok. The limit switch(mounted to pulldown motor unit is the other switch. This switch has a small plastic lever,a even smaller little tab,and has one screw retaining it to pulldown unit. I have replaced the switch on the pulldown unit 90 percent of the time. As i said earlier there is a chance both switches could be damaged. Hope this information helps you!

Trunk will not open with button


There should be a yellow lever inside the trunk near the back seat that you can pull. You will need to lower the back of the back seat, and stick your head in there and look up. Pull the yellow emergency lever and the trunk should open. It is mandatory to have one in case a child accidently locks themselves in the trunk. Once you get the trunk open, make sure the valet switch near the trunk latch didn't inadvertently get depressed. It should be either on the decklid on the latch or in the trunk itself below or next to the latch reciever. it should be a slide type switch that you can lift up or press down. Also make sure the trunk lock out button inside the glove box didn't accidently get pressed. Hope this helps
