Hey guys, new to the forum. I recently purchased a 2003 Grand Marquis LS Ultimate Edition. It has 34000 miles so I dont expect too many problems right away. The driver door unlock however is not working.
If I click the lock button it locks, but if I click the unlock button, the keyless entry module makes noise but nothing happens at the actuator.
1st I purchased a new actuator, however when I unplugged the wires from old actuator and put them in the new for a test, the same thing. Lock but no unlock. so the actuator is fine...
Also checked as many fuses as I could that related to door locks. nothing.
Any thoughts? Could it be the keyless entry module?
