I disassembled my driver door handle, please help me fix it ! :)

[Ande]

Symptoms, three long squeals instead of going in/out then it gives up.
The motor moves fine when applied 10v/ limited to 0.5A
The handle works well when stowing, but clearly don't know its position.
There are two internal connectors on top; LED and motor.
The lower 6-pin connector had some, not much, corrosion, I cleaned it.

The lower connector pin 1-2 are for the LED, 5,6 for the motor.
pin3-4 must be the hall effect transistor/or reed relay (whatever it is using)

one way - I measure 2v (as if there was a diode between), or 16Mohm
swapping the leads around the other way I cant measure any continuity.

The handle's position (and the magnet near the hall sensor does not affect the measurement. (!)

Does anyone know the "normal" / correct signals/levels ? - is the hall sensor completely enclosed, or can it be corroded? / is it worth opening?
are those two pins supposed to be shorted when handle is stowed(or extended?)

I have attached the photo of the handle assembly:

the "left driver side" - won't ship to Europe.. hooray
I reassembled the door as-is , there is some soft of hall effect sensor with high angular precision inside, and I do not even know if it is a reed relay based device or a semiconductor.

Hello Ande,
I have an 2018 MS and have the same problem, three squeals 2-3 seconds apart, then the door handle stops. Last night, it started to squeal and never stopped. I had to pull the door panel off and disconnect the handle control module.
How did you resolve your issue?
Thanks in advance!

Their post was from Oct 2021. I suspect their issue has been resolved

Agreed that their issue is resolved. That's what I'm hoping for, and maybe some feedback on how they resolved it.
There doesn't seem to be a lot of feedback on the Gen 3 handles. Some resolve themselves, some have to have them recalibrated, and some have the whole handle assembly replaced. This member seems to have a very good grasp of how the Gen 3's work. I know it's been about 1.5 years, but I figured it was worth a shot.
