I had a problem with the directional signal switch on my 1965 C10 several months back and removed the steering wheel and replaced the switch. Yesterday when I turned on the switch to make a right turn, the right front signal light flashed along with the left rear. In addition, when I depressed the brake the directional signals stopped flashing and both brake lights worked. If I try to turn on the signal lights with the brakes depressed, no signal lights work. I changed the flasher and it had no effect...same problem. I am pretty good on electronics and have a wiring diagram but am at a loss. What can I check besides removing the wheel again. The new switch should not have gone bad that quick.
