Dual Climate Control Repair

[finzup]

Apparantly the driver's side air temp blend damper has failed(low temperature in vent air). Anyone know how to access the air box? Dealer wants $1400 to fix it. Thanks

While checking another forum I belong to (Ford Explorer) I found this for the 2011 model year Explorer. Don't know what year Edge you have or if the two systems are similar (I would bet they use many of the same parts). You might want to see if there is anything for the Edge. I also see they are allowing 1.1 hours to do this job. Even with parts yours sounds very expensive.

Good Luck.

 

Looking at the schematic you've posted, part #7 on the list has the same numbers as the replacement part that is listed in the TSB I posted except for the first 5 digits/letters and the "C" at the end.

Doesn't look to be too difficult of a job for the OP if that will solve the problem. It also appears there might be a left and a right actuator. Maybe one for the driver's side, and one for the passenger side?

The passanger side blowing hot and driver side blowing cold

 

Blend door actuator on 2012 edge. I'm a mechanic and have replaced the blend door on a few F150s and it was a nightmare. Had to take apart the whole dash.

 

I was expecting the same nightmare on my wife's 2012 ford edge, it actually was vary simple just drop the glove box and it's right there you man have to take off the panel along the center console. These was extremely simply and can save you alot of money I bought the actuator at my local part store with the sensor and linkage for 50 bucks.

[sashields303]

Wow... $1400 for a $20 part and 10 min. Labor. Just when I thought the dealership service departments were getting more reasonable.I had this issue in my 2013 Ford edge Limited where the driver side was blowing hot air when the air conditioning was on. I found by reaching under the drivers side near the center console I could unplug the Blend door actuator and plug it back in and this remedied the situation. Unfortunately, the problem reappeared a few days later so I did the same action unplug and plug back in and fixed it. Has been working now for about a week. I have been having a hard time trying to find a part number for this actuator when I called the Ford dealer and ask for the part number they said they didn't get mad over the phone. So I still don't know what the driver side door actuator part number is for a 2013 Ford edge Limited.

[sashields303]

Sorry Siri got me on the previous post. What I meant to say was the dealership said they did not give part numbers over the phone

Thank You Thank You Thank You...

 

I have a 2013 3.5L Edge Limited, with 88k miles and dual climate control. Two days ago the drivers side AC stopped working, and would only blow the hottest air known to mankind. All the while, my wife sits comfortably in the passenger seat and has full temperature control. I live in California and it has been 100+ degrees outside for the past few weeks, so you could imagine my frustration. I popped into a local dealer to see what I was up against. The service tech told me it was one of 9 possible options, and worse case would be 250.00 with parts and labor.

 

Using the diagrams posted by autom8r (above), I was able to remove the driver side actuator, and move the linkage by hand. Walla! I have AC on the drivers side. I still need to order the part but at least I have something to work with. I've seen a few different part numbers so there's some research to be done.

 

I also read that these should be calibrated, or a setting in the ECU that needs to be changed. Can anyone confirm either of these claims?

 

Any help would be appreciated!

 

Thanks again for all the info so far... I'll keep you all posted on the final fix.

 

Happy Trails!

Hi wisdomsp,

 

Do you have any update? Is there some calibration required? I started to feel the driver's side being noticeably less cold than the passenger side with A/C on high or max when it is really hot outside. Changing the temperature to a warmer setting does make both sides warmer, just that at the coldest setting, the driver's side does not get as cold as the passenger side.

Further to my post, I found the procedure forreplacing the driver side blend actuator for 2007-2010 Edge,checked on my 2011 MKX and it seems I can't access the 3rd screw holding the actuator.

 

I did however confirm the actuator is moving, also reset the HVAC module using forscan. Yet, still the driver side is noticeably less cold. Could the actuator be defective by not moving all the way, yet is still moving partially? How can I check and what is the procedure to replace it? Thanks.

The FSM doesn't show a way to test the actuator separately.

 

Normal Operation

To rotate the temperature blend door actuator, the HVAC module supplies voltage and ground to the temperature blend door actuator through the door actuator motor circuits. To reverse the temperature blend door actuator rotation, the HVAC module reverses the voltage and ground circuits.

 

The temperature blend door actuator feedback resistors are supplied a ground from the HVAC module by the temperature blend door actuator return circuits and a 5-volt reference voltage on the temperature blend door actuator reference circuits. The HVAC module reads the voltage on the temperature blend door actuator feedback circuits to determine the temperature blend door actuator position by the position of the actuator feedback resistor wiper arm.

 

During an actuator calibration cycle, the HVAC module drives the temperature blend door until the door reaches both internal stops in the HVAC case. If the temperature blend door is temporarily obstructed or binding during a calibration cycle, the HVAC module may interpret this as the actual end of travel for the door. When this condition occurs and the HVAC module commands the actuator to its end of travel, the airflow may not be the expected temperature.

 

The blend door actuator may be working, partially, such as in a partially stripped gear tooth which used to happen with (non-Edge/MKX) BDA's in years past. Can you post a pic of the BDA in your MKX? Is it visible but not accessible with a tool?

 

I have seen a few posts come through that found that inadequate refrigerant charge can be a culprit in this situation. Have you had the charge verified?

Thanks for the reply. I just read you post. Actually yesterday I was able to remove the BDA, it was difficult (for me). After removing the BDA I tried to hold the blend door actuator by hand to full cold as much as I can but still noticed the driver's side being warmer than the passenger side. Though I still suspected the BDA, I just installed it back (harder than removing it) & set an appointment with the dealer to get it checked along with the refrigerant charge as per you advice. I know my dealer, if they feel I did anything they will then blame me for anything that goes wrong

[WWWPerfA_ZN0W]

Path of least resistance for the dealer, LOL. Good luck!

[omar302]

An update to my issue, dealer found AC charge was a little low & topped it up. Now AC is back to normal, both sides cold.

[WWWPerfA_ZN0W]

The Edge seems to be very picky about the correct amount of refrigerant in the system.

[PaulSchott]

I had a 98 Ford Contour that had a small refrigerant leak that would show up the same way. The drivers side vent would blow much warmer that the others. I never fixed it because it required a can of 134A once a season. I sold it before it became a problem. The guy I sold it to knew about it and replaced the receiver dryer. He showed me the old one. There was an insulating piece of rubber around it that collected water and rotted it out.

[WWWPerfA_ZN0W]

Do you think it could the same issue here, the receiver/dryer? I have seen it posted that the Shrader valves could be an issue on the high/low-side ports.

... I found by reaching under the drivers side near the center console I could unplug the Blend door actuator and plug it back in and this remedied the situation. Unfortunately, the problem reappeared a few days later so I did the same action unplug and plug back in and fixed it. Has been working now for about a week.

 

Same issue with the dual climate system and I have a 2012 Ford Edge SEL and want to see if I can simply plug and unplug the actuator to get it to work because I am not a mechanic by any stretch of the imagination. Do you happen to have a pic or a schematic of what that plug looks like underneath the driver seat? There are multiple plugs underneath my driver seat, and I want to make sure I unplug the right one so I don't mess up anything.

 

Thank you very much!

[enigma-2]

Could there be corrosion on the connectors that is getting wiped when you remake the connection, and re-corroded in a short period?

[sashields303]

Zachary, just find the blend door actuator, there's only one connector with 4 pins I think, squeeze the back of the connector and it will slide right off. Then just slide it back on, I doubt you'll mess anything up. And, mine has not malfunctioned since my last post. Good Luck.

[omar302]

Refer to posts #2 & #3 above. The blend door & actuator are not under the driver's seat, but under the dash on the driver's side.

[H.B. Riverol Jr.]

Hi Guys...thanks for the post...I have a 2012 Ford Edge SEL and had the same problem. Driver side hot air and passenger side cold air.

I simply disconnected the plug and plugged it back in, seems not to be a tight fit...Well the AXC is working now. Will attache a pic so you can see, the plug I disconnected is the GREEN one...thanks for all your help

[2kool]

thanks for posting everyone. 2013 edge sel 3.5. 76K miles, purchased used 1 year ago love it. wife says heat not working driver side...........unplugged said actuator clip and re-plugged.....working fine now. I have a dishwasher that does this that has a similar fine pin connector...same re-set works for it too. I blame humidity for dishwasher...not sure on edge but glad it is working now.

I had the same issue with my 2013 edge I replaced the actuator how can I reprogram my HVAC so the actuator will work?
