When I turn on right blinker it is a fast blinking. Left blinker blinks at normal pattern. I'm assuming it's the flasher relay. Does anyone know where that's located on an '05 Yukon?
Thanks for any help.

This usually occurs when a blinker bulb is out or if you change to leds. Check all blinkers, front and back.

When you change to LEDS they blink fast?

They don't draw a lot of power, so when you switch to leds in the blinkers, the vehicle thinks the bulb is out and will "hyperflash" when signaling. Letting the driver know that a bulb is out. And like 07burb said, load resistors will alleviate this problem.
