I have this sort of problem:
my seat belt light is blinking and my windows move up and down at the same speed as the seatbelt light is blinking
So i found with search that it has something to do with CPU#2, is this correct and where can i find it?

 

CPU 2 is under dash on the driver side kick panel. CPU 1 is there as well and is the smaller of the two. See body electrical diagram in the archives. CPU have controls for window and seat belt systems.

 

Ouuraiit, ill rip it open and see what i got under there. is the CPU usually broken and i need too get new one or is it fixable?

 

Never seen a broken CPU. Its basically a computer that monitors functions outside of your ecu. Hope your's isn't broken. Sure its not just a short somewhere or maybe a relay...hopefully something like that.

 

Ok, ill check fuses and relays and see if its one of em.

 

These can break (mine did) but it is not common. Often if the battery gets low these units can act a little strange. They are not repairable; just buy a used one from the classifieds if it is broken.

You can use to Body Electric manual in the stickies for testing procedures.
