The switch is easy to install after removing the door panel. I have a problem: the new switches are EXTREMELY stiff and difficult to operate. My wife complains that they shouldn't be that hard to push/pull (power windows). I'm not sure if they "loosen" over time (never happened before on a new machine or derailleur). Dorman is a good company and generally makes good quality products, but this Mexican made product does NOT look like original equipment. Works but doesn't look like a quality device. And for the price it should be.
