I had similar symptoms - rapid flashing of directional when headlights on and brake depressed when making a left turn, both directional indicators in dash light dimly when brake depressed, "Check Traction Control System" indicator On even with ATC turned Off and "strange" indications in tail lights.

Check the pins in the connector at the Lamp Holder Assembly for your Rt. Tail Light for arcing and corrosion. (The female pin is in the vehicle harness connector and the male is part of the Lamp Holder Assembly.) If found, because the male connector is part of the Lamp Holder Assembly, you'll have to replace the Lamp Holder Assembly and the harness section coming in from the vehicle containing the female connector.

I just repaired this problem in the left tail light on my '01 van with a part from a '99 van I found at a local salvage yard.

    It doesn't matter which side your directional flashes rapidly when you depress the brake pedal - the tail light configuration at the connector on both the left or right side is the same. Check your Right Tail Light connector pins for arcing and/or corrosion.



    IF YOU FIND CORROSION, TRY CLEANING BOTH SIDES OF THE CONNECTOR AT THE CORRODED PINS - IF THE SYMPTOMS CHANGE, YOU'RE IN THE RIGHT AREA!



    If you can find a used Tail Light assembly at a salvage yard, you'll have to replace the entire Lamp Holder Assembly (because the male connector is part of it) and make sure to cut off the female connector WITH enough of the vehicle wiring to allow you to re-connect once you cut out the old one.



    Remember, if corrosion is found, replacing just the Lamp Assembly won't correct the problem - you have to replace the female side too.

Left blinker flash fast, hit brake left blinker goes out left taillight goes out but both backup lights come on

Usually a fast flashing signal is because one of the bulbs is burned out or shorted out. If the signal and brakes use the same light which many cars do then check the wiring to it and replace bulb. If burns out again then it has a short between the signal switch and the actual light or the brake wiring to it is shorted.

99 Chevy Tahoe... Rear turn signals, brake lights, and hazards

I had this problem, and to be honest, it happened to the left side about a week later...it's the board that the bulbs plug into...it's a very common problem with this model. So popular that you can normally get the socket board off the shelf at a parts store! it's extremely simple to replace, and I replaced all the bulbs at the same time!

No, but that's probably where your problem is. The wires get the hell beat out of them by stones, and then they short out and cause problems. I would take a look at it.
