What do I need to look for to get dash to work?

That is a mess and points to nothing in particular, perhaps a communication issue with the BCM?

You need an auto electrician with a professional grade $5,000 scan tool computer with access to wiring data and the ability to read wiring diagrams.

The first thing you should do is check the fuses. It's possible that a fuse has blown, causing the lack of power to the dash lights, gas gauge, temperature gauge, oil pressure gauge, and instrument panel lights. If the fuses are all good, then you may need to check the wiring harness for any loose connections or damaged wires. If the wiring is all good, then you may need to replace the instrument cluster.

If the car has a BCM/PCM it probably needs scanning or replacement.

Mine was recently doing the same thing. In order to get it to work with the way it was wired, we had to change one of the glass tube fuses that runs the radio. The problem was that the radio and the dash lights were wired together. So if you had the radio and the dash lights on they would both blow. Don't know if this is a common problem though.

The daytime running light module is built into the instrument cluster of your car and if all the lights work normally with the headlight switch then you need to replace the dash[instrument cluster].A dealer will need to program it whether it is new or used,so plan for that as well.

Checked Every fuse in the fuse box (no small task).This includes #4 - Power point Instrument Panel, #14 - Day time running lamps (auto lamps doesn't work nor does auto lock), #27 - ignition switch run feed, #35 - Instrument Cluster, #41 - Instrument Cluster, #42 - Delayed Accessory, #45 - Ignition switch run/start feed, #102 - Door locks body security module, #103 - Ignition switch, #110 - Ignition switch, & #116 - Ignition switch. But I also check all other ones as well, they all register OK. AC panel & radio work. Turn signals work. Mileage does not work, trip computer does. So, basically, everything works except auto head-lights, auto locks, and the dash cluster (no MPH, RPM, mileage display, Fuel, Temp, Tran Temp, and Oil Pressure).

You have to remove the panel to check onthe connections behind it, also check the headlights switch, they tend to burn out.

Hello and welcome to FixYa . Locate the dial that controls the brightness of the dashboardlights. If the control is not immediately evident. Make sure the brightness control is turned on. If it is and the lights aren't working, the problem may be a bad fuse. Check the fuse that controls the dashboard lights Replace the fuse if necessary. If just one part of the instrument panel is not lighting up, then you have either a burned-out bulb or a wiring problem.

This should get you going. And you can always Ask Me.

The whole dash bezel has to come off but are all the dash lights out? if so check the switch for dash lights on a 01 it is built into the turn signal handle I think check it to make sure it's not set to off for dash lights

I'm going to suggest you check two things.

The first, obvious, thing to check would be both fuse panels. One in the vehicle, the second under the hood, and SHOULD be located in a box, near the battery.

Secondly, look for any ground that may have broken free, or the ends may be corroded.
