hi skippy,i had same problem on my zaffy a,it turns out that where the harness passed thru door the wires had snapped,does ur speaker in door work? i had to repair wires with small new lengths as it had snapped in two places,and was close to multiplug in door,real fiddly to repair !! could also be solenoid which is part of lock and handle,quite a big item and looks expensive ??as for removing door panel with door closed there are quite a few screws i almost missed a couple,then sacrifice the plastic clips (white ones cheap in most motor factors or dealer)when u pull panel off,u might have to keep sliding seat back and fore,best of luck with that one fella !!!!
