SC400 Trunk Release doesn't work
 

The trunk release on my 1992 SC400 no longer works. I am talking about the driver compartment release switch.

I don't hear any 'click' as I used to when I hit the button. I looked at the schematic, and I don't see any relay. I looked at the mechanism, and it is a DC motor rather than expected solenoid.

Ideas? Thanks!

had the same problem with my frist sc.

does it atleast open when you use the key? that worked for me. wish i had the answer for you, but i never fixed the problem.

i have the same problem with my 93

I have the same problem on my 93. It does works with the key. It all started when I had my remote start installed. It was off and on and now it's been broken for a few months :cry:

is it locked? may sound like its a stupid question but its easy to push the lock button in and not realize it (this happened to me :egads: )

are you sure your trunk struts work?
I still haven't replaced my trunk struts and b/c they are so worn out, when i hit the unlock button, it doesn't lift the latch out of the lock.
Maybe that's your problem?
It's a simple fix, i've just been lazy.

yeah that could be it too. i remember there being a lock for it.

i dont think the stuts lift it out of the lock, there should just be a piece of metal in the latch that slides up to lift the trunk hook out of the latch.

Mine is not locked and I think my struts are ok too. They keep the trunk lid open.

Dont worry, your not alone, that happened to me too. Took me a good half an hour to figure out what happened. hehe

More info on problem
 

Thanks for all responses. Here's more info:

1) Trunk unlocks/opens with key no problem.
2) Switch lock is not engaged, gas tank door release works fine.
3) Trunk struts are OK, just replaced (release still doesn't work, but trunk lid stays up!)
4) Trunk won't open when hitting switch with slight upward pressure on spoiler, so I believe it is the switch/release mechanism-- not the spring preload.
5) All stock. No aftermarket alarm system or other mods.

Thanks again!

Stupid me!
 

Aw $%#@!

It was the switch lock in passenger compartment. I thought the lock would secure both the gas tank door and the trunk release, but apparently it only secures the trunk lid. When I unlocked it trunk releases fine.

I feel dumb, but it's worth it to have the release working again. THANKS!!

HAHAH! atleast you solved your problem.

Just figured out my problem with my trunk release switch, damn thing was locked, i put my key in the lock right next to the trunk release knob and turned it, trunk release works fine now. D'OH. :egads:

Lock unlock trunk
 

Same thing I knew it was the lock un-lock near the switch, but my key had worn out and couldn’t insert the key all the way. Luckily I had a spare, unlocked it. Whew.

Thanks for the help.
