Lock button doesnt work any more??

[cpdenton]

I think I have got it figured out after studying my schematics for a few minutes.

you have a break in a ground wire or a bad connection on the drivers side door button.

here is the schematic that shows where the wire should be losing connection. if this wire is not grounded, when power is applied to the other side of the circuit, it does not get to ground.

now, that wire will be located on the pinout chart at one of these two locations.

i hope you are able to get it fixed. nothing more frustrating than something not working to me.

check at the lock motor to see if the voltage is changing when lock and unlock.
could just be a couple bad motors.
both switches must be hooked up in order to work.
the system picks up all the grounds from the driver side
possibility that you lost a ground on that side, bout the only thing makes sense
if there was a problem in the pk/lg or pk/y wires the locks would not work at all.

just went through all this wiring putting power locks a windows in my 03
