At this stage in the job, things are going pretty good. The plastic has been cut, the old broken blend doors
are out, and you are starting to see hope for having a heater again.
You should be excited, but don't celebrate just yet - there's work to do.
are out, and you are starting to see hope for having a heater again.
You should be excited, but don't celebrate just yet - there's work to do.
Start with installing the rear Jeep Heater door.
Align keyed shaft and slide into place.
If the rear pin is not aligned in a way that allows you to install
the door - DO NOT TRY TO TWIST OR FORCE THE PIN OR
BLEND DOOR INTO POSITION!
Instead - complete the AZC System recalibration process.
This will cause the motor to spin the pin around into position.
Install the second door (closest to you.)
Install Jeep Heater motor drive shaft through the opening by
aligning the two pins. The stop limit pin should be aimed
away from the blend doors.
| Time to test it all out. Once both doors and aluminum drive shaft connector are installed, you should check functionality of your system. |
Before sealing up the plastic air box, check for functionality.
Reinstall drive motor and wire connectors.
Start the Jeep and turn both temperature knobs to max heat
position. Both doors should lift into the up position (see photo
above)

Open the glove box and remove the two rubber stop tabs
on the top lip above the open door. They look like a
sideways "D" and can be pulled straight down to remove
them. If your glove box has a dampener on the side,
release the clip from the glove box to lower it down all the
way.
Work the glove box free from it's lower hinges.
Once the glove box is removed you will see a wire
harness and a small motor assembly held on by two
screws.
Remove the two screws from the drive motor.
Disconnect the wire harness. Set the motor in a safe
place.
Unscrew the single phillip screw aiming down on the front
of the black housing. Some vehicles use a metal clip that
can be pried off with a flat head screw driver. Set these
parts aside for later use.
Disconnect and tuck any harnesses up and out of the
way of the cutting area.
This is a close up photo with a yellow
highlight added for you to clearly see the
cut out line.
A pneumatic air saw was used here to
complete the cut. Any type of cutting tool
that can cut plastic can be used including
hot knifes, Dremels and rotary tools, air
saws and, electric body saws.
Click the photo for a larger close up.
Note the angle of the saw blade in the
photo. Cut with your blade skimming the
back of the section being cut out. You
should imagine trying to aim the blade
towards the drivers side headlamp. This
will keep your cutting blades far away
from your evaporator.
Take caution while cutting. The A/C
evaporation unit is just to the right of the
work area.

At this point the first of two cuts is complete. You should now
see the first blend door. This is the door that operates the
Drivers side temperature settings.
You will now need to cut out the plastic divider between the
two blend doors. This part can be discarded once removed,
as It does not serve any purpose.
Once the center divider is removed, you will see the second
blend door. This is what controls the passenger side
temperature range.

Once in place, your new JeepHeater blend
doors should move up and down when you
adjust the heat controls on your A/C system. If
they do not respond, disconnect your battery
for 30 seconds to reset the system.
Sometimes the computer will shut down the
motor if it senses a problem with the blend
doors. They will cycle once the battery is
disconnected for 30 seconds.
