My mom has a 1998 Grand Marques keyless entry system. Her front passenger side window will not lock or unlock using the key pad or the lock control switch. I ripped the door panel off and measured the voltage at pin 5 on the right lock control switch it measured 12V so the switch is getting the correct voltage? Does anybody know what resistance spec is and what pins to check to test the lock & unlock feature? I understand the lock motor is also called the (power door lock actuator motor and it operates in reverse bias) How do I voltage drop the actuator (confused because there’s two terminal and the motor works in reverse bias is the voltage drop spec .2V. Or can I do a resistance check on the motor and what’s the spec on the resistance test on the motor? I'm thinking because I hear the motor working on both the keyless pad and the door locks on both the driver’s side (master switch and passenger’s side switch) there is high resistance some where is the circuit. Thanks for your help. I do not have Alldata or Shop Key.
