I wanted to submit this because I don't want anyone to make the same mistake I did(I'll get to that).
So recently I noticed that while my temp control was set at 71 for both sides, the passenger side would just blow cold air. I did my research (I will save my rant how this happens with a 45K Jeep 2 years old).
I found the info on the gear and dove in.
1) always disconnect the negative lead to the battery.
2) removing the glove box. Nothing earth shattering hear pinch the sides and disengage the string that slows its opening. If you have changed the cabin filter you know all about that.
3)remove the piece the holds the floor duct and floor light (all push pins)
4) remove the surround that holds the glove box. Here is where I start to get in trouble. In the two upper rubber stops you have 15 Torx bolts...Yeah I didn't know but luckily I didn't yank too hard before I realized I should investigate. So you remove those two screws and the 4 exposed bolts on the bottom (2nd pic)
Also unplug the glove box light and floor light.




5) as soon as you can put a piece of tape (White) over the plastic edge in the pic. That is beyond sharp. I have a ton of cuts on my hands and wrist. You can see the actuator that has the broken gear just beyond the tape.



The actuator has two permanent locating pins and two brass colored screws (15 Torx) I removed the bottom duct work but not the top. I had a screw driver that had a ratchet for the two screws. Not enough room for a long screw driver in there so use something short or angled


This is what it looks like with the actuator removed. That is the gear for the blend door


Actuator removed and unplugged from harness with broken gear attached

You can't put the new gear on wrong because its keyed to go on only one way.

These are the two gears old broken one on the left. Part # 68214880AA was $2 at my dealer.



When you put the actuator back on with the gear on it, make sure it works freely.
I put it on the first time and it was off a tooth and did not.
After I secured the two 15 torx screws I reconnected the battery and started the Jeep just to make sure it worked without binding. It did!
Now put everything back in reverse. don't forget to plug both the floor light and the glove box light back in.
The part where I messed up on was that I thought initially that I had to remove the wood trim above the glove box. You don't but I did nic the wood by the center console. I also have not been able to get the trim around the passenger side vent to sit right. If anyone has some insight please help. All of that could have been avoided if I knew that it did not need removed. All in all pretty easy fix.
I hope it helps someone.
I need to know how you align the gears. I cannot even see the gears as I try to install the actuator?

Thanks
Don Fowler

Hey OP, thanks very much for the write up. Total effort and cost was 1 hr work effort and $3.50 for the part.

If you look at the new gear you will see that the center cog is a bit wider than the rest. That wider cog fits into the wider blend door gear.

I had the same issue that when I put back the actuator, I wasn't sure that I had the gears aligned properly aligned.

What I ended up doing is 2 things.

1. Before you unplug anything...turn up the temp on the passenger side to max. This will turn the actuator gear to face upwards.

2. If you look at pic #5 there is a round plastic collar below the blend door gear. I put the new actuator gear on there first then I attached the actuator to the new gear.

The actuator will line up almost perfect to attach to the new gear and screw holes.

Re: Passenger side Blend door gear replacement

Just had to do this again on the passenger side 2nd time doing it, if anything i can't stress how much TAPE is needed, and a 1/4" stubby ratchet will save your life.

Dealer had 2 in stock i bought both for under $5 total.

Re: Passenger side Blend door gear replacement

So, anyone do the driver's side yet?

I'm curious as to how involved it is. I think I might be experiencing the same issue cited here, but on the driver's side.

I had the dealer check it out, but they claimed they couldn't replicate the issue (i.e. the rattle sound during climate control activation/mode switch). They also claim it should be throwing up a code if the issue exists.

Regarding the latter, I'm not sure that would be true if the system actually operates, but is damaged and simply noisy at this point.

Either way, I'd like to look at it for myself but want to know how deep I'm going to be in it if I do.

Talking Re: Passenger side Blend door gear replacement

Wow! So glad I found this post. My passenger side heat hadn't been working for nearly a year, was told by dealer that the dash had to be removed @ $1000 for the job. Wasn't paying it so I just closed the pass. side vent for the winter, since cold weather is coming I wanted this fixed. My issue wasn't the gear, it was the actuator itself. Opened it up & found two gears missing teeth. Bought two actuators since there are 3 of them under the dash that control the heating & cooling & are all the same part #. replaced this broken one & let it calibrate itself. There is no need to disconnect the battery, just pull the 60 AMP fuse holder under the hood, it slides in & out. as long as you have the teeth lined up on the actuator gear calibration is automatic. Amazed that I saw a post saying you had to take it to the dealer after replacing it to have it calibrated (Bull$hit). The time it took me to take the old one out & replace it was less than one hour, (plus the time it took to open up the broken one) so ridiculously simple thanks to this post. I have so little trust in dealerships & always have, the only thing they are good for is diagnostics. Pull the dash??? Bull$hit!!! Pull the glove box & there are 2 of the 3 actuators right there. Drivers side is more difficult to get to so I hear. But I don"t think it would be rocket surgery like the dealers make you think!

Re: Passenger side Blend door gear replacement

Bought my Jeep over the weekend. Dealer said driver side had no heat, but passenger side did. I get there, and there is no heat on either side.

Is it likely both gears/actuators have broken, or am I looking at a bigger issue?

Re: Passenger side Blend door gear replacement

More likely than not that's the issue. I would start there, both sides are out on mine and I haven't gotten around to fixing it yet but it seems that the passenger side is easier to tackle than the driver's side. Are you going to do it yourself or go to a dealer?
