How do you remove door panel from 1998 ford f 150?

You should go to an auto parts store like advance Auto or Auto zone, and ask for a Ford door panel removal tool, then ask them for the basic "how to."
They can advise you on your particular model.
Also, pick up a couple of replacement door panel snaps, for they often break upon removal.

Get a stiff blade, like a putty knife, & slide it up between the inner door panel & the sheet metal door frame close to the middle of the bottom of the door. Slide this blade along that seam until you hit something. Then you twist the blade slowly, gently prying the panel off of the frame. There's a plastic 'christmas tree' fastener attached to the back of the panel that snaps into a hole in the frame - You are pulling that fasteners out of the frame. When the fastener is out of the hole, continue to slide the blade until you hit the next fastener. Pop that one out & keep going, until you get like half way up the side of the panel & there aren't any more fasteners. Repeat up the other side of the door. When all the plastic fasteners are loose, take the bottom edge of the panel & pull it straight-up & it will pop off of the door frame. If some of the plastic fasteners break, take a good one to your favorite neighborhood car parts store & buy a box or replacements.
