Hi Emmanib2003,
Not sure this is easier than getting a "new" CLP (I think new means one that isn't water damaged off of ebay or from a local junk yard), but the yellow lines coming out of the clp are pneumatic lines that are either pressurized or evacuated by the clp to open and close the locks. I don't remember if vacuum opens or closes the locks, but you can try both. Disconnect the pneumatic lines (3 yellow lines - one is for the drivers door, one is for the passengers door, the gas filler and the center console, and one is for the truck) from the clp and connect them to a pump. I would try vacuum first since you don't want to over pressurize the system and destroy stuff (you can apply as high a vacuum as you want), To make sure you have enough vacuum in the system, work on the drivers door lock first - it can be manually open and closed with the key - the other locks won't respond to the drivers door being opened or closed, but you're just trying to verify you have enough vacuum or pressure to open or close the locks. If you do use pressure, make sure to set your regulator to very low initially (~5psi) and work your way up. I don't know what the pressure should be, but I would assume fairly low since the CLP pump is tiny.
Good Luck, keep us informed
Sincerely
Jerry

PS. the easy way to get the pneumatic lines off the clp is to unclip the gray block that they go into - the gray block has a black clip in the middle that you partially pull out to unclip the gray block from the clp.
