2007 power lock issue.

Having issues with my power door locks. The master switch and passenger switch will only unlock and unlock the rear hatch. The switches will not work any other door including themselves.

I have already replaced the master switch. Assuming the new master is not bad any thoughts on the problem?

None of the other doors including it's self. The rear doors do not have switches. All windows work.

Thanks in advance for any help.

Hi TerryD,

Thanks for replying.

None of the door locks actuate except the rear lift gate. There are only two lock switches, The master and the passenger front switch. If I depress the master lock switch the only lock that locks or unlocks is the rear gate. Same with the passenger switch only the rear gate locks and unlocks. None of the four entrance door locks work.

I thought maybe it was a bad master switch so I replaced it. I still have the issue. As an FYI- all of the window switches operate properly.

Ok, I understand now! Thanks for the clarification.

Standby, let me check the manual. You might have a bad relay on the IPDM.

It may be a grounding issue.

Looking on the wiring diagrams and descriptions in the manual, the only thing the front doors have in common are the ground circuit. The DS door has a separate power supply than the other three doors.

You'll probably have to download the manual and start checking the grounds and fuses.
