Just recently we had quite a cold snap, much below zero. Now the heater will not go to the floor or the defroster, just blasts through the center vents.
Tough to drive because the windshield is frozen. On the floor it's cold toes. Then an overheated middle section. I live in Minnesota.
I've heard that Dodge knows of this problem (Blend Doors breaking or locking) but will not put out a recall for it. SHAME on you.
Have you checked with the dealer on a TSB specific to this problem? I hear what you are saying about the problem being a known issue. So maybe there is one out there on this. I'd check into that.
Also remember your truck is 7 years old.
Most TSB's come out of first year problems that recur often enough to warrant the mfgr to issue a bulletin on the problem and reimburse dealers for the work to correct the issue.
I can understand your pain Red Ram Girl. I have a simular problem, my heat only comes out of the defrost or the middle vents not the floor. I plow snow in Michigan and that can be quite cold on the feet after getting back in the truck after shoveling walkways.I have asked many people and got a wide asortment of answers. One told me it is a vacum problem one said maybe i droped something in the vent preventing the doors from closing. I hope we can get some answers here. Thats why i joined. As i read the problems from others it reminds me of the problems i am dealing with I hope I will be able to help others with something soon lord knows i have had my share of problems
When mine stopped working, it was the outside air blender door. It had broke off and fallen over the top of the blower motor. I removed the blower (3 screws) and stuck my hand up in the hole and just removed the door and then puit the blower back in. Took about 10 minuutes once I figured out what had happend. Maybe yours is the same thing?
Thanks for the information. I live in Spokane and as you know it's pretty cold this year and I just bought the truck. My wife has complained multiple time about not getting any heat to her feet. Maybe now I can fix it.
I had the same problem a couple of years ago. The doors break at the actuator. The extended warranty didn't cover it.
I found an aftermarket supplier of MUCH better quality doors & have replaced 3 three of them. I think the company name is "HeaterTreater" It requires a little surgery but isn't too difficult & beats the dealer charging $1200+ to put the same lousy quality door back in. Good luck.
Dodge will pull your whole dash to fix the heater & then they put the same type cheap WHITE plastic parts back in it
the after market parts are made of of a better plastic, not so brittle
But I also had a leaking heater core which is technically unrelated.
After spending saturday stripping my dash down to the firewall to get the HVAC plenum out, I found that I had a bad motor (I believe) It ohm'ed out at around 230ohms when the other three were right at 82-83 ohms. The blend door was cracked but not quite non functional. After putting all back together. I still had the malfunctioning controls but my leaking heater core was corrected.
I am fairly certain that my problem now goes back to the HVAC control panel/servo control. I will be trying that today.
My 06 wont get heat to the floor even after removing the blend door. Looking for the control arm that operates the plenum. Anyone know what is involved?
The blend door doesn't have anything to do with heat going to the floor or not. The blend door controls how much incoming air flows over the heater core and thus the temperature of the air.
Mode doors 1 and 2 control the airflow. Mode door 1 routes air away from the main part of the system (the main vents) and into the secondary system (the defrost and floor vents). Mode door 2 then controls whether the air flows to the defrost or to the floor.
No airflow to the floor is almost always a sign of mode door 2 failure. Unfortunately, mode door 2 is the one door that cannot be repaired without removing the entire air box system which as more than a job. A quote from Heater Treater....."Most people find it easier to wear two pairs of socks than to replace or repair mode door 2."
If you want some detailed info about the process, search "Heater Treater Dodge Ram" on Youtube. I haven't watched them in a while but I assume they are still there.
your doors are the problem that is the only thing that will keep it from changing you have to pull the heater control box completely out of the and then take it apart to install the new ones if you pull it put all the doors in it that is what I did plus I put a new heater core and ac core in while was in it here is a link to doors Dodge Ram 2500 3500 STEERING LINKAGE UPGRADE KIT MOPAR GENUINE OEM
After watching the videos and reading the stuff, I have come to realise that it is mode 2 door for me. defrost yes, floor no heat lol. I think im going to brave enough and go ahead and repair it lol
05cummins, have you attempted this yet? My past two Rams had the hvac issues. My current Ram hasn't broken yet but I'm thinking next summer will be dash removal time and replace all the doors.
Hey man, I got most of my dash apart and decided that I can deal with less heat on my side since the back heat and passenger heat still works and fully fix it in the spring. I did remove enough dash to get my hand on the motor linkage, so I was able to move it a little bit and I do have heat on my floor now. But its mixed between defrost and floor all the time until i switch to vents, even the blend for floor and vents is only floor as well. so i just keep it on floor for now. and it all only works on 4th speed now too, I dont have 1, 2 and 3 fan speed now. I got some work to do, but apparently the switch the speed should be easy enough to get as long as the factory amp isnt in the way of it. but currently -26 before windchill...i will wait haha
Dodge used cheap plastic on the door pivot points, it turned brittle & broke off
Sadly some people are replacing those same plastic pieces with other OEM plastic pieces from Dodge & in those older Dodges, they are also going to break again
2009 Ram 1500: I have had the K17 recall work performed twice now. I took it into the Dealer and they diagnosed another K17 actuator. It is the right temperature actuator. I have a case number with Dodge but Dodge told me that they will not cover it. I double checked the three actuators in the front that are easy to get to and they are good. I put my hand on the right temperature actuator and it is definitely clicking. Is there some type of consumer advocacy group that I can contact?
I am having a similar problem. Heat and front vents work defroster vents don't. Is there a way to get to the doors without taking the whole dash apart?
If you are keeping the truck, new Steel doors are a lifetime fix.
Mode 1 door is failed if no defrost and feet air. Another sign is AC never gets ice cold, as the cold air gets heated in the plenum. I don't like warm AC.
MD1 simply diverts air from the main front vents to the secondary part of the system. MD2 is the one that decides whether the air goes up to the defrost or down to your cold toes. MD2 failure is common on these trucks and unfortunately is the most difficult to fix. Heatertreater does make a kit but a large part of the dash still has to be removed to access MD2. Per Heatertreater.net.
