Front windows won’t open.

[Arek]

Both of the front windows quit in closed position.
Seems like it happened to others (other threads), but no DIY solution yet.

Left the car for a couple of hours and they started working again for a while.
After about an hour of driving both front windows (rolled up) quit.
Left it overnight.
Tried in the morning - they don’t work.
Installed new switch - still nothing.
Tried to reset the auto by holding each switch up for 15sec, then down for 15sec.

I have replaced the switch.
Same issue.

Any suggestions?
1. Unhook battery over night?
2. Would AlfaOBD be able to reset something?
3. ?

After 2 hours of simple troubleshooting I found that a white plug to the door module is suspect.
I unplug it cleaned the contacts, plugged back in - WORKS.
Reassembled the door, tested - does not work.
Taken apart, cleaned, plugged - WORKS
Left for a few minutes - does not work.
Pulled out and plugged in - either does not work, or only one window works.
Pulled out and cleaned contacts - WORKS.

I have done it multiple times.

So, now:
1. Is the module broken?
2. Is the plug broken?
3. Is something else broken?

I will order new module and test it.
Any suggestion where to order?
I am in Canada.
