Signals fast in the front and inoperative in the rear is an indication of an inoperative (or burned out) brake lamp. Check the rear brake/tail/bu light wiring harness, for it is probably disconnected. This harness is located just inside the rear bumper (or behind the trailer hitch if you have one). You may find two connectors. Also check the bulbs themselves. I used cheapo wire taps from Radio Shack to attach a custom trailer wire harness on my 1992 Suburban, and over time the road salt ate away at the exposed copper strands in the wires, giving me this symptom on a yearly basis.

NewHad the same problem with my 98 Suburban, found out that my tail light assembly is corroded, had it sand blast and it working superb. good luckNew My problem started with first one side, then a few days later it went to both sides. Turned out my cable under the rear bumper had caught on something when I was offroad driving, but it didn't completely pull apart to begin with. Then later, it finally parted all together. It took all of 10 seconds to repair it once I knew what was wrong.
Brake lights and turn signals are on a separate circuit from the tail lights. Tail lights are on the same circuit with the dashboard lights. If the dashboard lights aren't working either, check the fuse. If they ARE working, check the headlight switch.
No brake lights but turn signals work? Turn signal switch brakes route through it.
Turn signals use a relay or 'flasher' which is usually located on or near the column under the dash. Brake lights get their power thru the brake light switch on or near your brake pedal under the dash; check it with a 12v circuit tester.
my 98 suburban did the same thing. when i changed my headlight switch that turns them off and on, they started working again.
Bulbs blown/Brake lamp switch inoperative
ABS and brake lights on dash will be on. Speedometer and cruise will be inoperative.ABS and brake lights on dash will be on. Speedometer and cruise will be inoperative.
Answer Usually when the flasher blinks rapidly it's about finished. Try replacing the signal light flasher and see what happens. If you still don't have Brake Lights start looking for a short.
How do you replace brake lights
May possibly be in the multifuction switch on the left of the steering column!!!!
check the brakelight switch. it is located under the dash where the brake pedal rests. Hey its ritchie. If you can click your blinker down and then they work its you blinker switch,but this is my monte.
It depends on the vehicle but in general you would have one fuse for the signals and one fuse for the brake lights.
