1999 FORD F-250
Door locks will not function with activation by switch. Do I need to lubricate and if so, how do I remove the panel to do so?

It's very rare for one lock to get sluggish, and two at the same time even more so. You'd be hearing some attempt at working too. If both don't work suspect the wires between the driver's door hinges. If both don't work from either door, suspect water leaking around the windshield and dripping onto the GEM module.
