All Doors Will Not Unlock Using Transmitter (1995 Models)
- Unlock driver's door. Using voltmeter, backprobe BCM 20-pin connector. Check for a voltage pulse at terminal No. 6, while pressing UNLOCK button on transmitter. See Figure . BCM is located on junction block, behind lower left corner of instrument panel. If there is no voltage pulse, replace BCM. See REMOVAL & INSTALLATION. If voltage pulse is present, repair circuit between BCM and driver's door lock motor. See appropriate wiring diagram in WIRING DIAGRAMS.
- Check for voltage pulse at terminals No. 7, 8 and 9 while pressing transmitter UNLOCK button twice within 5 second interval. If there is no voltage pulse, replace BCM. If voltage pulse is present, repair suspect circuit between appropriate BCM terminal and suspect door lock motor.
