No run/start power. Accessories position works.  Timer module(?) under dash ticks about 4 times per second when door is open. No fuses seem blown, though we all know that means nothing.

 

Sitting outside kid's baby sitter's house so any help appreciated!

 

Have not had any prior issue with switch, behaves as brand new.

 

Even the headlights don't work, but batteries are juiced.

 

Under hood light works great, hitting hazards sounds like a cheap fart machine by emergency brake pedal. No brake lights.

 

Changed out 50 amp Battery fuse, no help.

I understand. Look for the power distribution center.ground... it's important. looking down in front of the drivers side battery, down on the flat part of the fender (kind of way down in there)  there is indeed a visible grnd. On both my trucks I couldn't find it, thought I was getting misinformed until I moved the wire harness out of the way and there it was. If you neglect anything don't let this one get away..... we had a member lose his PDC which burned up a month ago. It was neglect from a previous owner.

I need to go thorough my grounds sometime but being electrically challenged I can’t find half of them. 

Master ground locations.

• Engine block
• Driver side fender near the headlight. Most all PDC stuff goes here.
• Driver side kick panel (inside the cab)

Have you checked the two big CCD plugs just to the right of the valve cover? Sometimes that white bail gets loosened and you get intermittent issues like you’re seeing.

@trreed was certainly on to something.

The plug with the white gizmo was fine, but the other one had a white and black wire that had worn through the insulation and was grounding out to the dipstick. Can't fix today, but wrapped with electrical tape and put wire loom on the dipstick.

Will see tomorrow if it makes a nickle's worth of difference.

That wire seems to be a neutral, so who knows if it was a problem grounding to the dipstick.

 

CCD network will shut it all down. No way to communicate information. CCD + and CCD - are pairs. Basically, there is a signal ground that is all mirror image. So if one line or the other is grounded or missing then the computer ignore the other signal because its missing the mate and the existing signal is considered all noise.
