My daughter Melissa's 2011 6.7 Lariat truck has a nagging issue that the local dealers have been unable to correct. First, the truck does not have the Rapid Supplemental Heat option...so it is always a cold beginning. The problem is the heat does not always come on. Sometimes it works perfectly and other times there is no heat at all...even after running for an hour.

It has been in the shop twice. They have replaced the climate control module. It was very cold this morning and the heat failed to come on again...she is getting frustrated...

Anyone else had this issue?

Regards

 

any chance it has a remote start? if so' theres a tsb on it

 

Does she ever get a faint clicking noise from under/behind the dash? My '08 had to have both blend door motors replaced.

 

Hi Rick, if we can assume the module is OK, then lets try tracking it down this way.
Is there no heat even if the coolant temp is normal? If not, thermostat problem. unlikely.
If the coolant temp is normal, is the fan running? If not, will the fan run by manually increasing the speed? If not, fan problem.
If the fan is running and blowing cold air, then possibly a plugged coolant line to heater core. Again, unlikely.
Possibly a duct door not opening. Here, I am assuming that the system has a separate AC core and full flow heater core, with blend doors to regulate air flow. Even if the module is OK, if the duct blend doors are not operating, then the hot air from the heater core cannot make it into the interior. If the doors are stuck to allow air from the AC core, then that would be a potential problem.
Without knowing more, I would bet it may be a stuck blend door, either the mechanism or motor.

As a complete aside, I am fully supportive of you in your experience of being shafted by Ford. If I was aware of your experience with them, I would never have purchased this particular brand. You have my compassion, for whatever it is worth.

 

It has remote start...but only one key with that capability...when I picked the truck up in Texas, there was only one key. The dealer did not have the remote start key in stock so he gave me a remote entry/manual start replacement key. Both keys work fine for their intended purpose...

I called her and let her know...

Thanks

I appreciate your support. It is encouraging that some people understand. This week, the personal testimonials of acknowledged lost sales of new 6.7 powered Ford trucks rose to at least 33 trucks. How did that math work out for Ford...let's see...estimated profit to FOMOCO for a diesel SuperDuty is $10,000...33 times $10,000 = $330,000....if one subtracts the estimated real cost of the repair of my truck to FOMOCO at $8000...Ford has only lost $322,000 in profits so far...and counting...Good move FOMOCO...way to help that bottom line.

Ric, good to hear from you sorry it's under these circumstances, I know you played a huge role in your daughter buying the same truck as her dad.

Had a similar issue on a 150 and it turned out to be a bad thermostat.

Wish you, your family and everyone here at FTE a very happy 2012.

 

mine did it and it was the blend door.

 

I am having a similar issue with my 2000 F350 7.3L. Can someone point me at how to check the blend door?

 

If the blend door is inop at times. It should have a fault code stored in memory.
