my doors seem do what they want to, sometime they will lock and half way, i replay the relays under the dash and have the problem, what should i do now?

 

What year truck are you working on? Is this a aftermarket remote lock system?

 

1997 expedition factory system. thank you getting back with me on this,

 

Have you lubed the linkages and latches yet?

 

Certain year Ford lock actuators are known to be weak. Does it work ok with the engine running, but iffy with it off? The voltage in the system will be a little bit higher with the engine running, and that may be enough to make a weak lock motor work. Like the other poster said, lube may help it also.

 

SORRY I DID GET BACK TO YOU BEEN BUSY, I REPLACED ALL THE MOTORS AND EVERYTHING FINE NOW. IT IS A 97 EXPEDITION, EB. THANK YOU.
