2007 jeep chearokee drivers rear brake ,tail ,blinker not working , no fuse blown. left blinker signal blinking real fast. front works fine.

when you have a fast blinking light the front or rear turn signal is probably blown and for your brake light check your fuse.

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

Your right rear turn signal bulb is blown.Replace the bulb and the fast blinking will stop.

mporteous, It sounds like you have a light switch problem. I can't think of any other reason for the running lights and tail lights not working in this situation. Are your brake lights working when the headlights are off and how about when they are on? Do your four ways hazard lights work in these situations? Try all the lights under these conditions. The reason the left turn signal blinks very fast is because one of the bulbs are burned out. Try the left signal and one light (front or back) will stay on and the other will not come on at all. Replace the bulb that does nothing. Do this before you try all the lights in different situations. I think that you will have to replace the light switch. Good luck with this.

It could be a bad multifunction (turn signal) switch. The way that switch works, it is possible that it can turn on the front blinker and not the rear one. It also cancels the brake circuit so the turn signal can work with the brake pedal depressed.

However, a more likely cause would be a break in the YELLOW/BROWN wire at the rear of the truck. It is common for the connector to get corroded at the left rear frame area where the bed harness connects to the vehicle harness. If you have trailer connections spliced into the wiring harness, these connections are also prime candidates for corrosion. I would look there first. Inspect these harnesses thoroughly all the way up and into the tail light assembly.

If the wires under the back of the truck look good, then I would check for power coming out of the turn signal switch. The wire at the turn signal switch is plain YELLOW (with no brown tracer). It is Pin (M) on the turn signal switch connector. The front signal is a LIGHT BLUE wire at the turn signal switch Pin (H). If you probe these with a test lamp, they should both work the same except the yellow wire will be hot with the brake pedal depressed and the switch NOT in the left turn position. If there is no power at the switch connector, replace the switch.

Normally with the blinker blinking really fast, it's telling you that one of the bulb is blown, front or rear signals. Check your fuse, and fuse relay to see if it would fix the promblem

the fuse is broke

did you try to replace the bulb in the back normally when it blinks fast like that its just the bulb and its doulbe film thats why the brake and blinker dont work

any increase in bink speed is direcly related to a bulb being burt out.

the blinker is behind o next to the brake pedalit coul be the problem brake ligth swich is ataached to bhe brake pedalhold by two screws o pins first check for groud o positive
