not that I know of? Should be one-touch and the mirrors fold. There shouldn't be a need to keep the button depressed

Yeah my 2004 did that, drove me nuts, they flipped back out in a parking garage and bashed on a parking post I was TICKED, but the stealer did not take my word for it...

Push the button once, they fold, push it again, they fold out. You do not need to hold it down.
