'07 Yukon XL Denali Door Locks

[BSarteSr]

Not sure if this goes here, did a quick search and did not find anything that addressed this issue.

Recently, when the door locks unlock, the front doors (Driver/Passenger) unlock fine, but the rear doors do not unlock unless I hit the button on the remote 5 or 6 times. Now I know that when you hit the unlock button on the remote the first time, only the driver front door unlocks and you have to hit the unlock button a second time for all the other doors to unlock, but that is not the issue. Just the rear doors (Driver and Passenger) are not unlocking unless I hit the remote unlock button 5 or 6 times.

I know there are separate fuses for the front and rear door locks, thought there was separate relays too, but can't find them?

Any idea's on what is causing this?

BUMP!

Anyone have an idea what is causing the rear door locks not to unlock with 2 clicks of the remote, needing 5-6 clicks?

The actuators are going bad most likely... common problem with these trucks

Just both back door actuators at the same time?

Just a guess...

I concur...my tahoe does the same thing on the rear driver door. Frustrating as poop. I'm going to change the actuator since i think it's getting frozen or wearing out.

You might be right but I just doubt that both rear door actuators are going bad at the same time? Is that really a symptom of the actuator going bad?

did you find resolution on this issue? Mine dropped both at the same time. Will not lock or unlock.
