Re: Your Convertibles

Yes it is electric. It fires a couple solenoids that release the toneau cover. There is one on each side.
The good news is that there is a manual release. If you fold the seat down you can see those solenoids.
Attached o each one is a loop. Pulling on that loop manually releases the cover.

There are two safety devices that keep this thing from deploying by accident.
The car must be in park (or neutral I think) for the solenoids to work AND the
Trunk must be closed.

Be sure the car is firmly in park.
Be sure the trunk is closed.

There is a switch at the top of the trunk that senses if the trunk is closed.
You can bypass the switch if you have to.

If your neutral safety switch on the shifter is bad it won't function.

One other thing is to check fuses.

Congrats on getting one of these Verts!

Manual Release Loops: You might have to feel around behind the sail panel. It had been so long since I had needed to find mine that is what I had to do for this shot.

Re: Your Convertibles

In the trunk you will find the trunk switch. Some of these incorporate a pulldown instead of just a latch. These sometimes malfunction. Here is a picture of the top and bottom parts of this. If you look behind the Back trunk trim you will see the wiring for the trunk switch. You can disconnect and bypass the switch to see if it is the problem. It's purpose is to keep you from raising the tonneau when the trunk is raised and thus avoid crashing them together...

Re: Rear Hatch Release

I got my Tonneau release solenoids to work by

making sure the plunger shaft was clean. I may have polished off some corrosion, with a mild abrasive.

lubed everything with WD40. (Yes, I know it is not a lubricant, but it often works best!)

I removed the solenoid to body retaining screw. I ground off the paint from the contact areas on body and solenoid. I applied Dielectric grease to said areas, to prevent corrosion. I replace the black oxide mounting screws with shiny (cadmium) plated screws.

Not my Tonneau pops open properly.

Re: Rear Hatch Release

ok....after several years finally diggin into this...mainly cause I finally got hatch pull down working and had rear tore apart anyhow...SHOUT OUT TO West Coast Autoparts for the rebuilt up/down cycle switch. But here I sit not wanting to rip the interior apart to chase the wire from release solenoid relay...any suggestions...good power to relay to switch and through relay.... NO power to both solenoids OR trunk courtesy light which happens to be spliced off right side solenoid power.
