you'll have to pull off the interior panel. window in the up position. on the lock cylinder there is a clip that you have to pull off and an arm that actuates the lock. pop the lock out. reverse to install.

use an electrical tester with a sharp point tip, and poke through the coating into the wire at every 5".

this is the best wat to test the wiring.

I had the same problem, what I did to fix it was as follows:

• Removed the plastic light holders from the tail lamp.
• On each of the three bulbs there is a ground wire that is attached to the plastic light holder via a screw. Remove these connections and clean, I used some very light sand paper.
• Reassemble, Worked like a Charm for me, and I save a $90 charge from Firestone by doing it myself...
