Turn signal not working

2002 Chevy Silverrado 1500--The right front blinker does not work, new bulb and the fuse r f turn is good

Left rear amber signal light stopped working. Changed bulb with right bulb that has been working fine. Flashers work front only.
After trouble shooting wires, there is power to sockets, but now the right side has decided not to work also.

My 2000 silverado's back driver side turn signal does not work, and I tried replacing the bulb, and checked the fuses they were all good, and I was wondering what else I should check

Electrical problem
2000 Chevy Silverado V8 Four Wheel Drive Automatic 125xxx miles

i have a 2000 chevy 1500 silverado with a little more then 125000 on it. My dash seems to become a christmas tree in the fact that the lights come on and go off and come on agian and then maby go off. Sometimes they stay on for a while. Here is what happens and what comes on.
The abs light will come on, and then the parking break light will come on. And when they come on the blinkers wont work. Along with the blinkers not working they will come on and then go dim. Seems to go along with the rev of the engine. And when all this is happening alot of times, not always, the odometer will shut off, then come back on. It dont reset or anything. It just does not show. The fuel gauge will drop then go back, and the battery light will come on. When all of this happends at once sometimes the engine will bog down. And when that happends the speedo and the tac will drop along with all the other gauges. HELP ME PLEASE!

I dont know about engine power problem but dash problem maybe dash Belive it or not it is grounded behind the right head! Grab the small harness going down the firewall behind the head and pull. If you find them broken ground them some were else on the engine.
