Power window auto up
Hi all,
i'm trying to get the auto up of the driver window working in my st185, after disassembling the button housing it seems clear that the auto up is available but just blocked.
here a few picture:
as you can see in the bottom contact there is a blocking piece of plastic, i've removed it with a cutter
then to have the button make the "double click" , you should trim the plastic with a little rasp here:
then you need to add two diode:
ah, and while there you could change the green led for a nice blue one, it' s a normal 3mm one.

Re: Power window auto up
Enabling the auto-up was one of the first mods I did to my car! Good stuff.

Re: Power window auto up
Is there a way to disable it? If I remove the diodes will it stop doing it? My car has this and it drives me nuts. I want to see if I can make the passenger window auto down though.

Re: Power window auto up
definitely removing the diodes will stop it, but why?
it does a double click if you don't push it too far it will not go auto..
as for the passenger side there is no way of doing it it miss the relais.

Re: Power window auto up
I hate it, I'm not sure what was done in my car but it's damn near impossible to have the window at anything other than fully open or fully closed. If I want it open partway I have to look like an idiot with my window flying in different directions until I get lucky and it just stops the movement instead of changing the direction.

Re: Power window auto up
It should have a double position, first it goes up and down freely than if you press it further there is a second click and it goes auto. It seems that you miss some spring in yours, anyway you can totally remove the auto feature desoldering one wire of the solenoid from the board.

Re: Power window auto up
Cool mod. You should sticky this in the how-to's. What's the spec of the two diodes.

Good to know, I'll pop it apart and see if somethings amiss.

Re: Power window auto up
I just did this modification to a spare switch of mine. Not knowing what size diode to buy I just recycled some from a scrap computer.
These visually looked the same, maybe slightly smaller. . what's the worst that could happen if not the proper size? ?

Re: Power window auto up
any diode will work except a zener, the current is really low beacause it only triggers the relay

Re: Power window auto up
Well. . It didn't work and smoked on top of that. I did exactly what was written above. Maybe I used the incorrect diodes? Either way, I don't think I'll be risking another switch.

Re: Power window auto up
What I've seen so far. There could be an underlying issue that caused these. I'd be willing to try again but on a spare. Next time I'll use new diodes.

Re: Power window auto up
i think the problem is the diode you used, change them to black ones (normally the zeners are all made of glass) if you have it and repair the track with a bit of solder.
you can avoid burning another time by measuring resistance with a multimeter between the power pins or by placing a bulb in series with the power supply and checking if it light up.

I'm confused. . what did you use? Isn't that what you have pictured?
