2002 Cadillac Escalade Ext

Electrical problem
2002 Cadillac Escalade Ext V8 All Wheel Drive Automatic 116110 miles

hi, I have a 02 escalade ext and the lights for the gauges don't work, I've already checked the fuses, and the message center screen doesn't work at all either, also the lights and the numbers on the stereo and the letters or numbers on the trip computer (the one that says driver 1, fuel economy... ) Doesn't work most of the time and never at night but they do work after I run the truck for a little bit on the day........ What I want to know is if I can fix this by replacing the whole gauges and can I fix the other problem with the trip computer and the radio, what should I check and how I really cant afford to take it to a dealer or a decent shop... Thanks

I hope I can be of little help to you. I have looked at the intricate diagrams for the circuits you have mentioned (driver info center, instrument cluster, and radio). There is one relay that keeps popping up in all circuits. It is called "Body Relay Block" under left side dash near kick panel.

Ok that kind of makes sense but which one is the left side is the drivers side or the passengers side? How does it look is it inside a box?

Never mind I found it and is not the relay because I changed it and still doesnt work. (I noticed that with the key on the accesory position or all the way down it works the numbers on the radio and on the trip computer light up. When I turn the truck on and it turns the exterior lights on then the green numbers from the radio turn off as well as the green letters from the trip computer) what else could I check for to fix those lights and also for the gauges cluster if I buy a new one will that solve the problem with the lights and the message center? (The PRND123 and the mileage do work as well as all of the other gauges is just that they have no light)

***So, the lights do work, but turn off when the daytime running light or the headlight is on. Sounds about right? If it is, the problem lies in your dimmer switch. Try adjusting the switch. If turning the switch up and down does not work, you may need to replace the switch.***

Sorry to bother you but is there any way I can test it before buying it (its about 90 bucks and its non returnable) so I just want to make sure
