Default Guages and windows dying ??

Recently as I am driving, all of my guages will die and my windows will not work. After I park, and a few hours later, everything works like a charm! Today was third day of this issue and first time it actually went out and came back on in same short trip. Anybody have any idea what this could be and how to fix it? I dont want to live in fear of rolling down windows for fear of them dying on me while down. Everything else works fine including dash lights, headlights, high beams, automatic locks, stereo, and mirror adjustments. Just the guages and automatic windows coming and going. Any ideas? Thanks!

Thanks! I will look into that. I also speculate it could be the the the harness in one of the doors. Ill check the wiring on that to see if it is rattling or loose etc. Thanks!

Might be just a dirty contaminated ignition switch or/and key. Try squirting some CRC Mass Air Flow Sensor Cleaner in the key slot and the key. It did the fix on my '04 several years ago and just worked on my DD that had a no start issue.

Does this actually work to clean the ignition switch? This wont damage anything?

This stuff is made to clean the MAF small wire and yes, it does work It and evaporates quickly leaving no residue. It worked for me. Hopefully for you.

Start with the wiring that goes from the door to the chassis. Pull the rubber door accordion off the chassis side and fish the wires and connector out of the chassis. Make sure the pins fit tight into the female ends.

It is highly likely the act of opening and closing the door is what "fixes" your issue and not the sitting for a period of time. The next time it happens, you could stop, keep the engine running, open the door, and wiggle the wires in the accordion to see if it affects the situation.

Sounds great thank you so much! And you are referring to me simply checking to see if any wires are loose correct? Not actually removing any wires?

There is a male and female style connectors, the female connector has sockets, the male connector has pins, disconnect the two connectors and look for deformed contacts on the female connector. And no you are not removing wires.

What would be my course of action upon finding damage?

Here is an excerpt from one of Bill Curlee's posts. Bill is an active member on this forum.

The rubber accordion tube between the doors is a conduit for the door WIRE HARNESS. Disconnect accordion tubes between the door and door frame. They easily pop in and out.






The door connectors live inside the hole in the DOOR FRAME "A" PILLAR. Fish the connectors out of the hole in the door frame. Yes,,, Its Short and will not pull out very far.

Disconnect the connectors and examine the male and female pins. The FEMALE pins in the connectors are easily damaged by heat and vibration and distort. When they distort, they make a POOR CONNECTION and any vibration can cause the power to that module to turn on and off rapidly. This causes the serial data buss data corruption. My ZO6 brand new purchased by ME from a dealer in 02 had bad pins and it was NEVER disturbed previously!! CRAZY!

Here is a good example of a power plug with a damaged FEMALE PIN:



The only way to properly test the female pins for proper mechanical contact with the male pin is to insert a proper size male pin into the female pin. Here is a picture of a pin that I use to test female pins:



When you insert the pin into the female pin, you should feel resistance inserting and removing it.


To fix the pin properly you should replace it BUT,,, if your careful, you can use a metal pick (I use a dental pick) and bend the metal tong back in place so that it makes positive contact with the male pin.

Does the negative battery cable need to be removed before this?

The negative battery cable should always be disconnected whenever you work on electrical components as a matter of precaution.

This is what it looks like. Wiggling it has zero wffect on returning power to guages.




Female end for sure looks bent and in need of some sprucing up. Once i reconnected both and reattatched battery, i cranked the car and guages still didnt work. I wiggled these wires directly and nothint changed. Do you still think this could be the issu .
