FIXED: The problem was a underdash relay didn't get + on one side

 

Hi, I have a problem with my '92 1gen legacy sedan. Recently these broke down all at once. Power windows, door locks and power sunroof and I can't find out what's wrong. I can't hear any sound in the motors. The dome lights in front work and not the one in the center of the roof.The cigarette lighter works. Power mirrors work.

 

I have the wiring diagram and I've tried everything I know.

 

I've done all the following:

Replaced all relays (Under dash, in hood, behind ECU, Cleaner relay)

 

Replaced all fuses

 

Replaced big and small ECU (G6 AND JT)

 

Any help greatly appreciated

So the next time this kind of thing happens hopefully the first thing to come out for testing is the voltmeter, rather than replace a lot of parts needlessly.
