1) you could confirm that there is an infant mortality problem with these blend door actuators like there was on the previous WK.

2) you could clear the confusion and tell us if it's the $2 plastic gear or the $35 electric actuator that normally strips out and fails.

3) you could help us from getting ripped off by the dealer by describing if the repair is feasible through the glove box (as above) or if the dash needs removed (the story my dealer told me) and if an owner who is mechanical can do it.

4) you could tell us if there are any other weaknesses in the HVAC like the distribution box or the heater core my dealer replaced saying it was "clogged".
1,2, 4 - I can't confirm (or deny) any of these. Probably because I am not a technician or an engineer. I don't have access to any data as to how many (what percentage) of vehicles have this problem.

3- I would suspect the dealer follows the repair procedure in the service manual. Chrysler only pays the dealer to do warranty work. It is in Chrysler's best interest to come up with the easiest (shortest or cheapest) repair that actually works to fix the problem.

It sounds like drewbreezy's repair worked for him. I would assume he's somewhat mechanical (I'm not), but I don't know for sure. If you're out of warranty, you do not have to go to the dealer for repair.

It's probably not cold enough to replicate now. The dealer will say it's "working fine". I hope to not need the heat until next Fall. My B2B warranty is up next Dec.

I can understand that. I'm not sure if the air conditioning will be affected or not. Most people don't have air conditioning pointed at the floor.

I have found that on my 2014 GC limited, heater system is a little funky to operate in manual mode, so I've been just letting it stay set on automatic and seems to work o.k. at least for now.

I too have a broken passenger side blend door gear. I'm grateful that I came across this thread, not sure replacing it will solve all my Jeep's HVAC problems, but if it does it will be much cheaper than the $1,000 plus estimate from the dealer.

My question is about the first diagram on this thread and the actuator indicated with the red arrow. Can anyone tell me what this does? While investigating the broken gear I found that I am missing it completely, the wiring connector is there but no actuator at all. It seems it would open and close a curved cover above the recirculating blower.

I am trying to troubleshoot an intermittent blower problem on my 2011 G.C. Overland. Sometimes the blower responds to the control knob, but sometimes nothing. Then I'll be sitting at a light and everything will kick on full blast. Any thoughts? Thanks for your help.

The red arrow points toward the Recirculation door actuator.

my problem is very similar to this but its the drivers side that only blows cold air. i took apart trim under the steering wheel to peek at the actuator and if i disconnect the hvac control unit and reconnect it, it definitely still moves and may even work for a few days but when it moves to the hot side it seems to try and keep going then it just resets over and over until it decides to stop and stay put on the cold side. so im gonna rule out the actuator since it moves, and i also think the door itself is good because when its moving the air is changing temperatures. i think i may have the same problem with the $2 plastic gear thing but how can i remove it on the drivers side cuz its seriously tight in there and im trying to avoid removing the entire dash. any help would be greatly appreciated guys. the only temporary repair im using for now is to just disconnect the hvac control and leave it at about 70% towards the heat side and kinda hope it stays for a couple days.

im new to forums but drewbreezy if you see this since you seem to be mechnicially good can you tell me if you think this would work on the drivers side? and are the screws torx? or allens? thanks in advance

If I get a minute later at work I'll take a peek under the dash in a WK and let you know what I think. I've haven't done a driver side gear yet so I can't say off the top of my head. Passenger side actuator screws are T20 torx, I do know that.

i finally decided to try and fix my issue so i ordered the gear and took pics of how it went in case it can be of any help to anyone out there. im not sure how to embed the pics so ill just describe and you can scroll down to check the pic. i took off the panels under the steering column, the center console, and the side by the drivers side in order to see the actuator which controls the temperature for the drivers side and as you can see in the picture i provided, the screw i circled in blue is pretty easy to access with a t20 bit, the screw circled in red was an absolute nightmare because there is no way to get any tool slim enough to remove it. luckily i work in a shop so i cut a t20 bit in half and used a small 1/4 wrench to turn it as you can see in the pics. finally the actuator came out and the gear sits between the actuator and blend door. unfortunately i did all that for nothing because my gear was fine but i did notice it was different from the one i just ordered at the dealer and circled the picture so u can see what i mean. i decided to test the actuator a bit more though and suspected it may be the faulty part even though it moves and kinda works. well since i already had it all apart i actually took apart the actuator and determined it was definitely busted because it seemed to be skipping gears and when i took it apart i noticed the gears were all worn down and missing chunks. anyways as of right now my truck is still sitting there all apart while i wait for the new actuator to arrive and im pretty sure thats gonna fix the problem. oh and just to verify that door is not the problem you can move it by hand once the gear and actuator is out and lucky for me it seems to be fine because i can get full heat and full cool when i turn it to both ends. hopefully this helps anyone who gets this issue and doesnt want to pay thousands to have the dealer supposedly remove the dash...

Thanks for pointing me toward this ColdCase.

I'll try to document the process a bit, once my $2 part comes in the mail.

JeepCares, any chance of this becoming a Service Bulletin?

I doubt it as there is already a STAR case that gives information to the technician on diagnosing a concern of "Drivers Side Or Passenger Side HVAC Temperature Will Not Change And/Or Blower Speed Changes Without Customer Input." It's up to the technician to diagnose it.

Thanks for the reply.
Can't see though, your pic is too small.
