Technical Tipo locking windows stopped working

[Sisu537]

Hello! i have a factory optioned Late tipo that has self closing windows when you lock the car but my passenger side stopped working. i dont understand wiring much so i would appreciate if anybody could tell whats wrong. The window itself works from interior buttons normally but doesnt self closed when locked, it used to close itself halfway then completely when i lock it again and it just doesnt do it anymore. Genius is the brand that has made this module

Hello,

I'm 100% sure it uses the same mechanism as if you use the interior button. If it starts to close the passenger window, the electric module should also be the same.

What happens when you close the driver side window before you leave the car (with the button) and then use the module to close only the passenger window?

Might be that the battery is too weak. Can you connect a multimeter to the battery terminals and observe the voltage when the windows are closing? What are the readings?

It's because you've parked the car with the wheels so steered on one side!
Nah, just kidding... It's only my OCD that's affected by that reckless parking of yours...

Your problem is most likely caused by oxidation on the windows circuit. Checking the battery voltage, as recommended by @the green vanper is good advice, low voltage can cause this. But I think it's oxidation, which technically has the same effect, low voltage to the window's electrical motor.

I had this problem many years on my Punto, driver's window. The window wouldn't move when pressing the button (there's no self-closing on Puntos), first on high humidity whether. If I insisted pressing, it would go. So I had it like that many years, but I knew there's something wrong. A couple of months ago it just wouldn't go at all, still high humidity. Then I fixed it. Started with the contacts on the door, the electrical motor. But those were ok, cleaned them with contact spray anyway. The thing is there was only 10.xx V at the motor's end when pressing the button. I went to the other end and there was the problem, at the contacts in the buttons control panel. Cleaned those and windows works great, be it rainy or sunshine.
Here's some pics.
You're welcome!

battery is brand new (as in it had a good charge i just came back from a trip) i tried with driver side closed too, it doesnt even move.

my window closes and opens normally when i try it from the buttons basically like the manual way, my only problem is that it doesnt self close when locked though everything else works. motor is working fine and is working at a normal speed.

i also apologise you had to see my parking! i was in a hurry to go upstairs so i forgot about it, dont worry i have quite the ocd too haha
(ps. i will try to remove the door panel tomorrow and see if its oxidation, my car has been sleeping a long time and is entirely original so i bet it even has the factory motors!)

Yes, I got that. I'm saying there is oxidation on your window circuit. You gotta locate where it is exactly, I can say it's on the part that activates the self-closing. Perhaps there is a module that controls that, if so it might be easier to access than behind the buttons panel. Unplug the wires from that module and clean them contacts.

yup! there is a module but its sort of central (idk if theres a seperate one for each door) but the self closing and central lock module is located buried under the steering column/dash. i have lot of time tomorrow so i can try cleaning the motor of the malfunctioning side and see if its just oxidiation or something thats about wiring that i dont understand

but thank you again! i am trying to keep mine factory spec as much as possible since its quite a rare example from what i have seen (maybe less than 10 or one of one since it has an abarth kit?)

but you definetly may be right, it could even be a burnt wire with these old fiats, at least they look pretty

 

[Sisu537]

turned out its from the module itself, tried cleaning and stuff but its not sending signal to the window motor to close itself. central locking works fine at least. gonna take it to electrician sometime to fix it since i dont understand much electrics

 

[Mike1alike]

It's probably some burned out transistor on it. Easy fix.

Hoping so! just gonna close it myself until i find a good mechanic who understands these cars's electrics

Drivers door kock micro switch or wiring may be involved. Any problems here can cause havoc.

I think his is LHD, but yes, faulty wiring on any side is bad.
