check the switches first for continuity when no force applied.

There is no such thing as an underhood wiring diagram. Wiring diagrams are grouped by SYSTEM, not location. So you'd have to get separate wiring diagrams for the charging, fuel injectors, sensors, lights, etc. Even then it's difficult to get the exact diagram. Read this post on what's involvled.

brake lights on chevy astro not working, need wiring diagram

The fuse box is underneath the dash.

Check the red 10amp fuse marked 'LPS'.

To check it, pull it out with pliers or needlenose. Look at it. If the wire inside it looks burnt, it is. Replace it with a good one.

There is also a dimmer switch on the dash. Check to make sure it didn't get turned off.

Replace the hyperactive lighter. Some do that.

Hope this helps,

Mike
