Electrical problem
2000 Chevy Epica 6 cyl Front Wheel Drive Automatic 300k miles

I am working here in Saudi Arabia and bought a used car with some minor problems which I presume.
The following problems are;
1. Outstanding SRS Alarm.
2. Automatic door at the back not working
3. automatic window at the back not working

Actually, I wanted to bring in the workshop for chevy but I didn't go yet since I want to it by myself only I don't have the manuals.

Is it possible to get manuals form your office?

I do appreciate your great support.
Thanks and regards.
