Before you replace the door switches, try spraying a penatrant into the lower portion of door latch, the complete latch, then followed up with a 'lite' lube spray.. The problem with these pin type switches is that their mounted on the 'underside' of the door latch with the pin 'pointed' upwards.. There isn't any seal on the actuating pin and dirt/debris collects and makes its way into/on the switch/pin making it stick..Sometimes with a little work they come loose.. Worth a shot prior to pulling the trim panel/s... If you can borrow a diagnostic scanner, or know someone with one, it will tell you which door circuit reads 'open' in the body system data...
