Hey guys,
I'm back again with another exciting saga!
Out of nowhere a couple weeks ago, I turned on my 1992 Saab C900 and the passenger window wanted to go down automatically. I can hold the switch in the UP position and get the window to go up, and then turn the car off so that it stays up. Otherwise, I have taken the switch pack out of the car to avoid burning issues and having to deal with the phantom window...
I am experienced with taking the pack apart to clean it and I have now done so twice to no avail. I am assuming that this may be a deeper issue than that Auto Down "Tang" that makes the window go down in one push.

Any ideas I can check before potentially cutting the tang first and then ordering a new switch pack altogether? Being that this all started out of nowhere, I lean towards there being some sort of internal short in the switch pack, but on first glance it looks clean.

Thanks
JRi

Swap the one-touch relays under the back seat, see if the problem moves too.
The window motors have a thermal overload swich that shuts the motor off if it overheats (sticks 'On'), It works again after cooling off.

Where do these one touch relays under the back seat reside? I do not see them on the fuse/relay block there, just the fuses for them. I have seen the relays on the actual switch pack but those are soldered into the switch pack circuit

And for the record, the passenger side relay on the switch pack will release when unplugged but snaps closed and engages window down when I plug the pack in…

As a last resort, you can remove the auto down electronics of your switch pack and solder in some new wires. I've done this for 2 of my cars:

Ok thanks
Question: does the circuit board just pop out of the switch pack? I was having some trouble figuring that out and didn't want to break anything

Thanks
