Where is the ground points located?

[SweSupra]

Hey everyone!

I just got done with my new MHG and everything was so good, until today when my power windows didnt work, just a sec later i realised that the seat electronics and central locking system did not work either.

And from what i have red i noticed that all of these things goes to the same ground point. The TSRM says Under left front pillar, and thene i saw somewhere on internet that is located on the seat bolt, so before i tare the whole interior down, does anyone know of this problem or where the ground point im after actualy is located?

I feel worried avout having my care unlocked at night since my back door lock is out of service :P

Its a -91 7M-GTE

Thx!
