I recently bought a 2000 Cadillac Base DeVille it is mechanically sound and drives well. My problem
right now is the Drivers side door and the rear left passenger door buttons do not work all!
They Still light up i've checked all the fuzes and the modules on the door,
they seem fine there is no difference with them and the right side modules. the strange thing is there
is nothing popping in the dash that there is some kind of problem or to service anything. Please
help Summer is coming and i do not have the funds to pay to take it to GM

==============================
check for codes -
pay attention to DDM - Driver Door Module - codes -

check the #5 fuse under the back seat -

check the wiring harness where is goes through the door frame -
the wires can break from constant flexing -
