Rear window loose

THIS IS A TWO PERSON JOB!!
Open the door wide for access. Get a look at each hinge and see if the bolt heads are accessible. If not it will involve stripping door trims and possibly front fenders.
If you can get to the hinge bolt heads, first remove the door check strap across the centre line of the door. This will allow you to swing the door a bit wider making access easier. Wind the window down a short distance as a handle. Then,
SUPPORT THE WEIGHT OF THE DOOR!
Slacken the LOWER hinge bolts leaving them in loosely to act as a brake if the door drops.
Start to remove the bolts in the upper hinge. Get your helper to support the door as it starts to swing loose. Take out the loose upper and lower bolts and remove the door.
To refit the new door, get your helper to hold it in position while you install the top bolt in BOTH hinges. Then install the lower bolt in each hinge. Tighten all bolts to the correct torque.
Lastly, refit the door check strap and close the door to check it lines up.

Hi. Thanks for your question. For any assistance related to Mazda rear glass window hinge you can visit https://www.reliable-store.com and download the entire workshop manual which includes all the information along with the diagrams for better understanding. Good day!

Here is the repair procedure straight from Ford manual, but it doesnt give any information about access problems, I will ask a coworker and see if he knows:

Removal and Installation

1. NOTE: Front and rear door hinges can be removed and installed using this procedure.
   
   Support the front door (20124) or rear door (24630) for service using Rotunda Flexi-Work Table 156-00070 or equivalent.
   

1. Mark the location of the front door upper hinge (22800) or lower door hinge on the front door or rear door and body.
   

1. Remove the door hinge-to-body retaining bolts.
   

1. Remove the door hinge-to-door retaining bolts. Remove front door upper hinge or lower door hinge.
   

1. To install, position the front door upper hinge or lower door hinge to the front door or rear door and body. Install retaining bolts.
   

1. Adjust the front door or rear door as outlined. Tighten hinge retaining screw and washer assemblies to 25-35 Nm (18-25 lb-ft) and remove the support.
   

Take apart the latch at the rear, and you should be able to swing the window open and access the screws on the hinges.

SImple thing...........try to tighten the door hinge screw or else there might be some loose screw at the air cond blower.

those nuts are 5/16ths.

Hey there.You can purchase a door pin and bushing repair kit to tighten up the hinge area,requires removing the door to replace.If the hinge area is worn to badly,the brass bushings willnot last.Also your window crank handle is held on by a C-clip behind the handle in between the plastic shim and the handle which requires a special tool to remove or a small screwdriver to get the clip off.It is hard to see.The shaft that the handle is on are known to wear also and if thats the case you will need to have the window regulator replaced.Hope this helps.John.

Get it fixed under warranty. My 04 and your 06 have the same glove box. The right hinge was rattling around in mine and they replaced it no problem. Not worth trying to fix yourself :)
