THE REAR WINDOW WONT OPEN/UNLOCK ANY IDEAS? THERE ISNT A VALET BUTTON AND EVERYTHING ELSE IN THE CAR FUNCTIONS NORMALLY
Did you try going to the back of the car and hitting the unlock button twice or the #4 Button? the sensor for that lock is in the rear bumper from what I see and the 5ft range suggested in the manual may not cut the mustard so to speak. It may be time for a new battery!
I have a c-30. I have never seen an unlock button on the rear hatch. However, mine will not open unless the car is stopped and you pull the key out of the ignition. Maybe they want to make sure you don’t accidentally open it while moving and the dog jumps out. I can only unlock it with the “trunk unlock” button in the key; as far as I know, there is nothing on or in the car that opens it without the key.
