Right rear door is loose on my 2002 ford ranger edge model what will I need in tools and how to remove and tighten door?

Yes to the programming.

You get out your $5,000 bi-directional, prograde scan tool computer and set it all up. :>D

This is not really a job for the home mechanic, but you can try it if you wish. Buy the unit and call out a mobile auto electrician. or a mobile auto locksmith / alarm installer.

Most GMs are pretty much the same. Remove the inset around the door handle - there may be one screw and then it should slide out.
The panel itself is held in with plastic retainers - probably 3-4 along the bottom edge and then 1-2 on the sides. These need to be pryed loose. If you can't get them with your fingers, use some other non-sharp object to help.
Once the panel is loose, keep it close to the door and slide it up - releasing the edge right next to the window glass. You may have to work it back and forth a bit.
When you put it back, getting the edge by the window on right is key to holding the panel on correctly. Many people don't get this seated right and the panels always are loose.

remove interior door panel(need special tool to pop plastic clips holding panel to door)with panel off remove plastic film,with window up you should be able to see two 10m nuts-bolts to remove-also have to pop lever off that goes down to door latch

Copy and paste this into your search window: 2002 ford ranger rear brake diagram

You should see four pictures pop up, select the brake parts diagram or the brake picture.

Brake light switch It is on the brake pedal

loosen the bolts and insert a body shim, that a local body shop can in most cause give you, behind each bolt and tighten that will kick the door edge away from the body.

Thats cause the truck is governed at 90 mph it cuts off the picks right up at 85mph. But most trucks cut of at 100mph
