Tail lights and dash lights are not commin on. back up lights brake lights and turn signals all still work. I think it has something to do with some type of switching device for the day time running lights. Its a 2000 escalade 4x4. Under normal secumstances the 2000 escalade can not run its fog lights and high beams at the same time. When my tail lights are out I can run both my fogs and high beams. To me it seems the day time running lights have kicked on and and now i cant turn on my own lights, and even when I do my day time running lights are still on so the tail lights and dash light dont come on.

Your tail lights and brake lights are on a separate electrical circuit mainly because your brake lights need to be activated by the brake switch in your brake petal. Check the voltage regulation circuit in your dash light circuit to see what is faulty.

The ground wiring on newer vehicles is a little complicated. Older cars, the ground would have been to the body around the tail-lights, but these have a ground wire in the harness and is connected to the turn-signal switch, and other sources. I don't think you have a ground problem. Does the fuse blow as soon as you press it into the fuse-block, or when you step on the brake? I believe you have a dead short somewhere, possibly a pinched turn-signal wire close to the tail-light assembly. Brake lights work through the turn-signal wires from the turn-signal switch on the steering column. That's how you can have one side blinking for turn while the other side stays on for brake. I'm kind of shooting in the dark here because I don't know what all you've done. If you replaced the turn-signal switch in the steering column, you may have pinched a wire or something there. Another thing, if the fuse doesn't blow as soon as you press it in, will both turn-signals work as long as you don't press on the brake? If you can provide a little more information, I might be able to help you more. One last thing....Have you replaced tail-light/turn-signal bulbs? If so, be sure you used the right bulb. You should only have two bulbs, one for back-up lights and one 1157-type combination for tail-lights and turn-signals. I have seen people use a single contact (1056) bulb in place of a 1157, which creates a short from brake/turn-signal back into the tail-light circuit. I do have a 1994 Dodge Dakota.

The dash and tail lights are on two different circuits, and the brake and turn signals are on different circuits, so at least 4 circuits total.
I would start at the headlight switch and check for power on the first two issues.

check park/tail fuse regarding dash ,park ,tail problem .brake light on passenger side is probably the brake globe needs replacing .Turn signals on passenger side could be globes or switch,check globes first ,if globes and fuse are ok ,may well be the switch especially if park switch and turn signals are on the same switch lever/stalk

yes ,
check the fuses.

Fast flashing dash signals mean there is a bulb issue-DEFINATELY!

The odds are the one fuse is blown for the dash and the tail lights. And the wrong bulb may have been put in for the brake light. The brake light is feeding back into the tail light circuit causing the fuse to blown out.

Change out the bulbs with OEM bulbs and replace the blown fuse. That should fix the problem.

If only your brake light in middle of rear window works then your other bulbs are bad. If brake lights all work in the back than bulbs are good. If you put turn signal on right or left and the bulbs light in front and back then you need to change multifunction light control box under dash. My understanding is it cost $600 new. So I would try used.

there are two turn signal flashers under dash one on fuse box and one next to the light switch have to look up behind dash behind light switch for second I had same problem

I had the same problem with my 1996 Mystique about a year ago. The brake and tail lights stopped working, except for the center brake light in the window. Turned out to be oxidation of the terminals at the connector on the turn signal. Yes, that's right, turn signal. The electrical signal to the tail lights goes thru the connector on the turn signal. To fix, I cleaned the contacts and the brake lights started working again. Hope this helps. Cheers, Henry
