2008 250 superduty. My passenger side climate control does not work. It stays cold . Anyone know what would cause this and then how to fix it. Momma wont ride with me until I get it fixed. So if I could get some knowledge from you knowledgable people that would be great.
I posted this earlier but some how it went to the wrong place.
Thanks
Ron

 

Come on I know some of you will know this help a guy out so I can get my girl back in my truck

 

Your passenger side blend door has failed...........it's a pita to get to...it's behind the glove box. There's a self test procedure to get error codes for your climate control just to verfiy.

HVAC Module — EATC On-Demand Self Test
The HVAC Module — EATC On-Demand Self Test will retrieve on-demand (hard fault) DTCs only, it will not retrieve continuous DTCs. Continuous
DTCs can be cleared when exiting the HVAC Module — EATC On-Demand Self Test. Make sure to retrieve continuous DTCs by carrying out the HVAC
Module — EATC — Retrieve Continuous DTCs procedure before clearing any continuous DTCs.
• The HVAC Module — EATC On-Demand Self Test will not detect concerns associated with data link messages like engine coolant temperature or
vehicle speed signals. A scan tool must be used to retrieve these concerns.
• The HVAC Module — EATC On-Demand Self Test will detect concerns in the system control functions and will display on-demand (hard fault)
DTCs for concerns that are present during the self-test. The vehicle interior temperature should be between 4°C-38°C (40°F-100°F) when carrying out
the self-test. If the temperatures are not within the specified ranges, false DTCs may be displayed.
• The self-test can be initiated after cycling the ignition switch from OFF to ON. Normal operation of the climate control system stops when the self-test
is activated.
• To enter the self-test, press the OFF and DEFROST buttons simultaneously and release, then press the AUTO button within 2 seconds. The display
will show a flashing blower icon for 20 seconds, after which all vacuum fluorescent segments will be displayed if there are no on-demand DTCs
present. If DTCs are present, the HVAC module — EATC will display "00 00" and then on-demand DTCs. Record all DTCs displayed.
• If any DTCs appear during the self-test, carry out the diagnostic procedure. Refer to the HVAC Module DTC Chart and follow the ACTION for each
DTC given.
• If a condition exists, but no DTCs appear during the self-test, GO to Symptom Chart Condition: The EATC System Is Inoperative, Intermittent or
Incorrect Operation.
• To exit the self-test and retain all DTCs, press any button except DEFROST. The HVAC module — EATC will exit the self-test and retain all DTCs.
• To exit the self-test and clear all DTCs, press the DEFROST button. The HVAC module — EATC will exit the self-test and all DTCs will be cleared.
• Always exit the self-test before powering the system down (system turned OFF). Once the self-test is exited, the ignition switch must remain ON for at
least 30 seconds to allow the door actuators to automatically recalibrate.
• Continuous DTCs will be deleted after 80 ignition switch ON cycles after the intermittent fault occurs.


HVAC Module — EATC — Retrieve Continuous DTCs
The HVAC module — EATC will retrieve only continuous (intermittent) DTCs when carrying out this procedure.
• Retrieval of continuous DTCs can be initiated after cycling the ignition switch from OFF to ON. Normal operation of the climate control system stops
when retrieving continuous DTCs.
• To retrieve continuous DTCs, press the OFF and DEFROST buttons simultaneously and release, then press the recirc button within 2 seconds. All
vacuum fluorescent segments will be displayed if there are no continuous DTCs present. Continuous DTCs are indicated by the presence of the Celsius
symbol (°C) on the HVAC module — EATC display. Record all DTCs displayed.
• If any DTCs appear, carry out the diagnostic procedure. Refer to the HVAC Module DTC Chart and follow the ACTION for each DTC given.
• If a condition exists but no DTCs appear, GO to Symptom Chart — Climate Control Systems condition: The EATC System is Inoperative, Intermittent
or Incorrect Operation.
• To exit and retain all continuous DTCs, press any button except DEFROST. The HVAC module — EATC will exit the retrieved continuous DTCs
mode and retain all continuous DTCs.
• To exit and clear all continuous DTCs, press the DEFROST button. The HVAC module — EATC will exit the retrieve continuous DTCs mode and all
continuous DTCs will be cleared.
• Always exit the procedure before powering the system down (system turned OFF). Once the procedure is exited, the ignition switch must remain ON
for at least 30 seconds to allow the door actuators to automatically recalibrate.
• Continuous DTCs will be deleted after 80 ignition switch ON cycles after the intermittent fault occurs.

 

Uh...what sxrfun said. I think! It will most certainly be the blend door. When mine went on my '08, I had the dealer fix it. They pulled the dash to do it. There are some who have done it without pulling the dash, I hear (or remember reading anyway). Through the dealer though, it cost somewhere around $800 to fix. The other blend door was fine, but they asked if I wanted it changed out while they were in there, and I said sure, why not. It all worked fine after that, and still until I traded it in. I sure do miss that dual zone climate control.

 

I did a write up in the tech section on how to change this in 08 single climate control sys. I imagine the dual has a different configuration but the approach will likely be similar. Give it a read.

 

I will check that out. Thank you all for your knowledge. I will read your write up and take it all into consideration on if I want to tackle this issue or cough up all the cash to have it done. It will depend on special tools if any and time to do it.
Again I appreciate all the help
