Okay so my dash lights don't work. My head lights and brake lights work but when I turn on my lights the dash lights or instrument panel does not light up. What could be the causes of this? Also my stereo system does not turn off with the turn of the key and when I get in my truck to go to work the next morning I usually find my battery dead and car won't start. Any ideas

My car remote control stop working and I want to troubleshoot the fault. How I do this?

I was driving and the screen
was yellow with red and black lines. I went into the store and when I came out and started the vehicle it was blank. My radio works but I can't see what station I'm on or use the phone, backup camera, GPS, etc. All the hard reset articles I find are for a 2013 or newer. Any help is appreciated

I took the old radio out but I don’t know which wire does what

My 1999 Cadillac Escalade has a new fuel pump a new fuel relay a new bank one sensor one heater circuit sensor O2 sensor.

Hello, its getting pretty snowy and cold around where I live and I have noticed that whenever I use the rear defog button on my HVAC unit, only the rear window defogger turns on. Both the rear side windows have defogger lines so is this a temp dependant feature or is it something else? Ive tried using a multimeter to test for voltage and neither side has any voltage.

Any help will be appreciated thanks.

It seams power isn’t getting to several unrelated functions and I don’t know why. Keyless entry is the most missed, as well as the driving lights, which seemed to stop same day. Cigarette lighter is all the time issues but fuse isn’t blown 🤷. Cruise control may not have worked when I purchased the truck, idk. A/c is a pain and after $3000 it still not working correctly. Is there any common point they all get power from because I can’t find any blown fuses

It all comes and goes all at once. , several lights on dash warnings lit several no comm thru according to obd2 port. Definite communication issue intermittent. Seems to happen all at once then back again. Ive unplugged cleaned connectors on fuse boxes in engine compart side dash and in driver footwell..Some come and go daily. Every ride is different every key start is different.

The anti-theft want true off.

Air conditioning is not blowing cold air
