I don't know if I understand the problem. Are you saying that one of your rear doors don't open when you click the unlock button? Yep, have that problem. My hubby took the door apart on my car and apparently the connection that unlocks the door is rubbing against another part. He fixed it but it went back to it's cheatin' ways. I am gonna open it up tomorrow and take a look.

Back lift gate/glass would not open or release. Even when unlocked with the key fob or the unlock switch on the drivers/passenger door. ... How To Install Replace Rear Lift Gate handle 2002-09 GMC Envoy Chevy Trailblazer ...
first is fuses are they good.?
the locks on cars are solenoids.
im guessing all ways to open it fail,
keys, key fobs, and internal controls panels?
no childern locks set (some are hidden on cars)
no drivers, panel , master lock, he pushes it and all locks freeze?
this is a general statement.
so you use a thing like a volt meter. $10 at walfart.
we check for 12vdc across the 2 solenoids.
12vdc when active is good.
0v is bad,
if you get 12v then the solenoid is bad or jammed.
if you get 0v, the controls are bad.
its that simple. and electro magnetic solenoid, is easy to test.
with any voltmeter made.
if the controls are bad we use the same method to check them.
12vdc to the switch it must be.
then you push the rear switch and 12vdc leaves this switch.
if not the switch is bad.(input good)
How are you trying to open the door , button on key fob ? With this system you can pull up on the drivers handle an it activates
Antennas in the external side door handles (C30/C70 front doors, S40/V50 rear doors)
Antennas in the passenger compartment and cargo compartment
An antenna in the rear bumper
Quick lock motors in the lock units in the side doors
The remote keyless entry (RKE) receiver receives a signal from the key
The switch in the clutch pedal (manual transmissions) or a signal from the brake pedal switch via the central electronic module (CEM) (automatic transmissions)
Switch in door handle and lock button on handle .
If a door handle is pulled outward, a switch closes that wakes up the system and activates the antennas in the handles on the side where the handle has been pulled out. If a valid key is within a radius of approx. 1.5 metres from the handle, the relevant door will open and the vehicle will unlock one or several doors. Which doors are unlocked depends on the settings for the system. The vehicle can also be unlocked if the handle is affected on the tailgate.
Make sure the striker plate is adjusted right. That's the piece that the door latches on to on the door frame. It should have an adjustment. You may need a special wrench to loosen it and move it to a better position. I hope this helps.
hi jim, try lifting up on the driver's outside door handle slowly while turning the key in the unlock position. The lock cylinder design has a cam on it that usually will catch while lifting the handle. if you have no luck on the driver's side, try the same thing on the passenger's side. be patient, it make take a few tries before the door unlocks.
