TURN SINGLE BLINKER SWITCH WHERE IS IT LOCATED AND WHEN I TURN THE TURN SINGLE SWITCH THE LIGHT STAYS ON IT DOESN'T BLINK

sounds like flasher unit failure

replace the bulb with the correct one, sounds like you have a single filament bulb where a double filament bulb goes and it is back feeding power through the parking light system when you turn on the signal.

There is only a few things that can cause blinkers to blink continually, meaning if your saying they wont shut off, Normally it is the blinker flasher or a fuse. Sometimes it can be in the blinker switch itself. I first would check the flasher, and turn signl fuse. If the blinker stays on and does not flash, still can be bad flasher or fuse or a ground problem, You would then have to check the wires around area where there contact to the tail light blinkers and front blinkers. But first start as said earlier with checking flasher fuse, switch and fuse. Mike

Sounds like a bad ground to me, although i am no expert.
i would be checkinh all connections and take it from there, a little wd40 might just solve it short term.

there must be a bad bulb somewhere

Yes, put the RIGHT BULBS in the right sockets.

Be mindful of single and dual element bulbs.

THERE IS A BLINKER RELAY UNDER THE DASH. IF YOU CAN GET ONE OF THE BLINKERS TO BLINK YOU CAN HEAR THE RELAY LISTEN CLOSLEY THEY PUT THESE THINGS IN SOME HARD TO GET PLACES

TEST FRONT RIGHT BLINKER CIRCUIT AND REPLACE THE BULB,,WITH PROPER BULB...A DOUBLE CIRCUIT BULB IN A SINGLE SOCKET WILL DO THAT ALSO A SINGLE SOCKET BULB IN A DOUBLE SOCKET HOLDER....CHECK LEFT SIDE BULB FOR ACURANCY

TURN SIGNALS WILL FEED BACK THROUGH THE TURN SIGNAL SWITCH.THEY ARE INDEPENDENT OUT SIDE ON THE CAR BUT NOT IN THE SIGNAL SWITCH.REPLACE THE SIGNAL SWITCH

could be both unrelated issues at the same time

worn indicator stalk
faulty relays

adjust or test the brake pedal stop light switch
