Rear liftgate won't open seems like it is locked. Anyone know how to get it open manually? All other doors and liftgate window works fine. Need your help
Thanks

 

Welcome to the forum. Try spraying penetrating oil into the lock cylinder. Then take your keep and spray it with oil and move it around in the cylinder. Can you feel the handle turn fully clockwise and counterclockwise? I've had my rear gate feel like it was sealed to the frame if I didn't use it recently. Sometimes it just needs a good tug to get it open.

 

The problem is Expeditions don't have a key for the rear liftgate. I have had to use the WD-40 fix on the doors. I can't get the lock solenoid to acuate or the lever mechanism is broke one or the other.

 

Sorry. My 90 does have a key cylinder.

 

You might have to work the interior panel off and gain access to the mechanism that way.
