Mak, Lock actuators, pull the panels, remove door handle-BE CAREFUL there’s little plastic connectors for the rod that are 18 years old. Watch the actuator as someone hits the switch. Something may be disconnected, broken off or just not working properly. I had one door that the lock never worked, I put a new actuator on it it worked for about a week and then stopped. Turns out all the fine dust in the locking mechanism kept gumming and wanted to push the actuator of the fingers that hold it in place. I used electrical cleaner, Engine degreaser and basically continue to use the actuator until I cleaned it out and now it works flawlessly.

Regarding mirrors, First do you actually have POWER mirrors? Then fuses, connections then bad motors- then upgrade to late model truck mirrors!

The first door always takes the longest, but by the last one, I was finished in 10 minutes. Great video from A1 and a good price on the parts. Next job is the power fold/telescope and heater tow mirrors like on my brothers 2011 250. Mirror envy is a thing. A little scared of all the wires though. Good reading for the winter months. Thanks again for all the current info.
