H3 driver side window and doors lock
 

hi,
i have problem with my 2007 H3. Doors lock doesn't work and driver side windows are not working too. Keychain doesn't work too.
i have tried:
-pulling out fuse 8 and 68
-taking out control panel and checking if it has dust or something
-disconnecting battery for 30 minutes for computer to restart (computer restarted(my keychain signal was lost but I programmed it again))
those methods didn't work
i saw that my keychain trigger anti-thief mechanism but no door lock
i also saw that I can program door lock in computer. To do that you need to hold door lock button on control panel for 3 sec with key in lock position. So door lock button is working but doors lock mechanism isn't working
i don't know what to do because I live in Poland so I can't give it to dealer.
thanks for help

Check battery terminals, and battery. If battery goes below 12 volts it will cause this issue. Once you change battery the lock and window with will reset.

I have replaced old battery with brand new but it has not changed anything. Terminals are ok. :/

If you have the stock OEM battery terminals, they are NOT OK. They suck and are known for failure, replace them with an aftermarket set.
