You might be right... maybe someone put the wrong bulbs in (like heavy duty or something) and it's confuzing the flasher.
I know that heat gives more resistance, so maybe when the bulb gets hot from being on, the resitance increases past the tolerance of the flasher (making it think a bulb is out), then cools off enough from shutting off that it goes back within range. I think that could case an erratic flash if the new switch doesn't help...
I know older flashers relied on resistance to let you know a bulb was out, dunno if these do or not, but LEDs make them flash fast (or in the case of older cars, no flash at all).
