Strange Window Drop

How is the panel removed to access the FEM?

From our friend Thunderbird Bob:

A couple of things to consider if you're removing the FEM that the video might not address:

1) FIRST DISCONNECT THE BATTERY !! and move the driver's seat ALL the way back.
2) Those two decade old electrical plastic connector housings are FRAGILE - be patient and don't force anything
3) Get some DeOxIt spray and clean out the harness connectors and FEM connectors before reinstalling
4) That top post that holds the upper nut is LONG and you have to finesse the FEM off of it, again be patient.

Thanks, Frank. I’m wondering if I could just have a poor connection.

[Frank Dreano]

Thanks, Frank. I’m wondering if I could just have a poor connection.

Its not impossible - I was getting a Trac Lok warning light that stayed on in the instrument cluster and after fiddling with some connectors it went out and never returned - that was 18 months ago.

Thanks, Frank. I’m wondering if I could just have a poor connection.

Removing and reinstall inserting the cables several times can clean the connections.

Have you checked the fuse and the window switch?

[007Cruiser]

Which fuse should I be looking at? Are you saying #20 in the rear power box?

[HKS]

Yes, we replace all the components that typically fail. Additionally we fully test the module in a working car both before and after the rebuild (the other places only bench test).

For the engine fan modules

On the 2002 it's PCM and Hydraulic fan solenoid

2003-2005 it's PCM and ETC (Electronic throttle control) to accommodate drive by wire

Bob,
Your test procedure is fantastic and beyond the call of duty.

I would thinks so as its labled FEM Left Window, another great video on the fuse purpose/locations:

So the saga continues. Today was the day to tear into this thing. Had two mechanic friends over to keep me from screwing things up. First thing we did was to check the battery. Everything was up to snuff. Then one of the guys checks the window. It works except for the drop (had stopped working altogether). He reset the window drop program and now it works! No idea why it’s now working normally. I’m going to keep using it and see what happens.

[Frank Dreano]

Pretty clear to me what happened, anytime you call in the "pros" to help with an issue, the problem goes away...
We've all been there...

Some creature in another dimension is now wondering what happened to their window drop...and why socks keep appearing....

[Brad]

I've had quite a few FEM'S that are flaky and intermittently work or don't work. I had one where if you turned the lights off and on 10 times the cluster lights would work again.

My engineer has a theory that continuing to use a failing FEM may be why some become unrepairable.

Was the window your only issue? Could have been a dirty/corroded contact.

[007Cruiser]

The window was the only issue, Bob. We shall see how long it keeps working. I think something was perhaps loose in the FEM or switch. For now I’m not looking a gift horse in mouth. My 1975 window is also acting up. You can’t make this stuff up. It’s like a car conspiracy.

My theory is that socks disappear only to become hangers in the closet.
