finally installed my lft rear lock actuator I got last summer,(old lock was still working, but last your it was getting tired so I got a new one). took all 4 door panels off and checked all cables and linkages and lubed them up including the handle mechanism all were really dry but good to go now. hopefully they don`t freeze up this winter. just to let you know these panels a very easy to work with, just make sure you know where the clips are and always use the plastic clip removers, and for the wood trim start at the narrow end first and work your way up to the wider end ,also unclip the inner door handle cable first,take out the bottom light, switches, and if you have the lighted door handle be careful not to break the light holder too make sure you unplug it. takes about 5-10min to pull panel off .
