How to replace window encoder when the bugger is stuck open!
Discussion
Morning all.
So the drivers side window wont close, new encoder ordered, pop off the door panel...
where's this new thingie go... not obvious at all!
perhaps the gubbins I'm after are behind the open window, which of course is now inside the door, so I cant get to the motor or actuator....
Maybe I'm looking too hard and it's staring me in the face!!

OK, you've got the door card off and the rubber damp membrane lifted/removed?
The glass and associated mechanism is in the fully 'open' position?
The encoder is held onto the top of the lift motor by a small machine screw. I think you need to remove the window glass - pretty easy - look at the bottom of the glass, and you'll see 2 off clamping devices that hold the glass. Un-clamp the glass (c/sunk allen bolts), and lift the glass, carefully, out of the runners.
Looking at the motor, you'll see fairly heavy gauge wiring to the motor itself and lighter wiring going to the encoder...both go to multi pin connectors.....Give both connectors (& encoder pcb) a spray with contact cleaner and try window lift rotary switch. It may work now!
Swapping the encoder for the new item is pretty straight forward.
....Also check the micro-switch behind the lock-plate on the B-post...Make sure the actuating lever is well located and the switch is being 'made' when the lock is closed. This switch 'tells' the window ecu the door is shut when it is electrically 'made',, and allows the window to be lifted to shut position.

Yes, to the present state, door off, rubber sheet lifted.The glass and associated mechanism is in the fully 'open' position?

Hadn't noticed the glass would be that easy to get out! That would solve all my issues! Will finish my coffee and get out and get it sorted!
Thank you!

Thank you both!
Seems these are pretty rare, Racetech dont seem to have them, and tvr-parts seems the only other place that do them on an exchange basis and not a hint of a second hand one on the interwebs!
Turns out I've got the slightly "rarer" ME0427 from the very early tuscans....
Thanks for the suggestions on repair! I'll give them a call next week.

Looks like we are having the same fun this weekend with windows! Glass is very easy to get out, bit of an awkward job to do...but isnt everything on the Tuscan?!
Out was about 30 seconds, Took me ages to get it back in and aligned in the runners properly! Still, Glad I finally found the issue.
yup, centre console.
There's a bolt under the ash tray and one at the back under the air vent.
May be two screws on the "wings" of the trim under the window controls on yours too. Should just lift off easily enough then.
Two ECU's are large black boxes, size of two packs of fags at a guess... you cant miss them. Easily disconnected and swapped over to test.
ETA it;s likely the part number will be written somewhere on the box of tricks too, mine was hand written on a bit of masking tape stuck to it!
Also, ETA, they are "behind" as in towards the rear of the car, the gear stick and hand brake. Where your elbow would be if you were resting your hand on the gear stick.

I'm guessing it's all hand built electronics hence the size, probably all components soldered to a board by hand, and then stuck in what appears to be a massive heat sink.
My understanding is they take the input from the door switches, window winders and window optical sensors/encoders, to work out where the window is, and where it needs to be based on opening/closing door and input from the occupants.
Weird it just started working again, perhaps a slightly dodgy connection on the plug, may be inside the unit too so it could come back. At least you know where it is now.
I seem to think mine started with "sluggish" opening/closing of the door and also the window, then stopped working altogether. Fingers crossed it keeps working.
