2011-2017 Jeep Grand Cherokee WK2 Drivers side Blend Door repair walk through guide. 

If you have no heat or AC on one side of the vehicle this is most likely your problem.

Here is the part number for the gear: 68214880AA

Please note. The new gear looks slightly different than the old gear but it is the correct part.

STEP ONE:You need to remove the silencer panel by your knees. Disconnect the hood release and unplug the switch for the lights and gas cap. (6 7MM bolts total )

STEP TWO: Underneath that panel there is a metal plate with four 8MM bolts . Remove those and take off the plate, Remove the bracket that the plate mounts to on the right side (4 bolts, two 8mm two 7mm) The left side can stay.

STEP THREE : Remove lower air duct. There will be a plastic fastener holding it in place. Remove it. It will be no good after you remove it. Replace with zip tie.

STEP FOUR: Make your own tool. You will need a 1/4 wrench link bellow and t20 torx. You could also cut the T20 torx bit in half with a angle grinder, I will show you what it takes to do the job with out cutting it. JB weld it or tape it to the wrench.

STEP FIVE: Completely remove the lower t15 screw on the blend door actuator with your new tool. Simple!

STEP SIX: Remove the upper difficult screw on the blend door actuator.
STEP SEVEN: Replace the gear. When you install the new gear just line up the gear center to center of the blend door gear. 

STEP EIGHT. Test your work before you install those difficult screws. Hold the actuator in place with your hand and see if it operates correctly by using Heat and AC.

STEP NINE: Replace the F@$%ING screws.

STEP TEN: Grab a beer and give yourself a pat on the back! You just saved a ton of money.

STEP ELEVEN: Put it all back together!
