I have the head light issue where only 1 low beam works. I have the model number off the current one in my truck which is a P56051040AD the problem is finding a new one. I found another one that says it is compatible, but is hate to buy something so expensive and it not work. The other model number is P05026034AA. Does anyone if this is true or not?

 

I've got the same issue. One headlight works, intermittently. Also have other electrical issues and they're starting to build. Left rear window inop, left rear door lock inop, intermittent operation of right front window, intermittent op of driving lights. As I said, the list is growing. (I believe left rear door problems are isolated from the rest of the truck since there are multiple problems with that door.)

It is my understanding that as long as the numbers match, we're good to go. P56051040AD is the same one I've got. If we can find a 56051040XX, I think we'll be ok. But.................like you, I'd love to find out for sure.

Anyone in the know watching?
