Hey, my speedometer and tachometer lights don't come on and my heat and A/C stopped working; like it's not getting any power no lights come on. my headlights still work, and I've already tried checking all fuses none of them are burnt out. These happened at the same time randomly 2 days ago.

This is common when the multiplex unit goes out which is under the left side of the dash. Here is how to change it out to help fix the problem. Check out the images (below). Let us know how it goes.
