Haven't verified this in some years but I recall the micro switches are sealed to prevent or minimize oxidation, just as are relays.

YMMV

FWIW my bet is you'll determine that microswitch is flaky. Or remotely possible, the latch needed grease.

(If I lose I'll buy you a Philly Cheese Steak sammich at Carlisle.)

It's a physical plunger-actuated switch mounted on the liftgate latch. It's small but should be visually apparent on inspecting closely the latch. Has to look like this: Screenshot_20200316-172725_Firefox_copy_428x664.jpg My supposition is that in your latest testing of the circuit it worked as it s...

You wrote "Applying 12V to the solenoid operates it, but I get no voltage at the connector to the solenoid in the lift-gate." (I realize I'm beating this horse...) In rereading your posts it seems you may not have yet actually inspected the micro switch (CD. Brad's photos above) mounted to the liftg...

Have you removed and checked the lift gate microswitch? If it's non-op or flaky per your Multimeter at least try spraying some electrical contact cleaner around the pushrod. Or, use an exact knife/razor blade to shorten the plastic boss at its base.

Great (total, start to finish) read!

Might even re-read this thread, it's so well detailed.

What a great tool. I might buy one to keep as an emergency key if myTibbe keys are lost or misplaced.

It's an '89 model change (auto and manual trans).

Who knows why the brake light circuit is always powered?

Have the cowl cover on my two Scorps, better than no cowl cover. But they can be improved by gluing fine mesh window screen to the under side to keep prevent small organic material from passing through the cowl cover holes.

Small wire brush or crocus cloth (fine grit sandpaper) works well.

Re fuses and relays too, it's good P.M. to periodically remove and clean the scuzz film that accumulates on their legs that might otherwise contribute to increased resistance at the harness connections. Continuity testing say at the metal tops or the legs may not be as indicative of absence of an is...

Decaying of or loss of a ground doesn't result in a fuse blowing. A short to ground (as e.g. a frayed wire, or a squished wire contacting metal) of a powered wire results in the classic short circuit and very soon after if not immediately a fuse frying. So I'd look at/around the undercarriage where ...

Just brain storming: since the speedo went out possibly the VSS wiring spawned a short circuit.

Anyone know who now owns Jack's former Scorpio?
