Elect problem - driver window, dash heat&AC, camera & compass

[Nonno]

Need help solving electric problems. Friday night driving on bumpy road backup camera & compass went dark and came right back. Assumed some connection under dash loosen up. Saturday's trip no problems. Today just prior to reaching our destination the driver's door window stop working. It was working fine 10 minutes earlier. Then I noticed the backup camera and compass/outside temp went dark again and did not come back.

While checking connections under dash I figured I'd try the dash heat/ac and they were out too.

The control on the dash heat/ac was in the position to send heat/cold to your face. When I moved it to off the camera and compass came back plus the window would move very, very slowly for a second or two. Fuses appear to be fine. Connections (ones I could find/reach) appear tight. If I move the control from the "off" position camera and compass go out.

What am I looking for? Loose connection, loose ground, crossed wires?

Thanks for any ideas.

I'm no expert in 12V systems, but I believe in looking for the simplest solutions first. I would think you're looking at a loose ground. Sounds fishy why several electrical components would fail at the same time. I know bad grounds can be real gremlins in these situations.

Well the window, camera and compass/temp seem to be working again. Driving again tomorrow so I'll see how they react to bumps again. Technical work done: wiggle, squeeze then wiggle and squeez some more.

Fan on dash a/c & heat still not working. Hope I don't have to use my favorite tool!
