At any setting other than full cold, the AC is blowing warm-to-hot air at the passenger footwell. This does not sit well with my Birkenstock-wearing sweetie. Took it to the dealership and all they could say was "well, we checked another pickup on the lot and it does that, too. SO...it must be working correctly."

That's the same answer they gave me when I complained that I had little or no heat coming out the driver's side foot vents at full heat in winter. Any techs out there that can confirm whether this is just crappy design on the part of Ford or whether my service guy has a lazy tech working for him?

It's not usually hot enough up here in the PNW for full cold, I like to blend in a little heat to take the edge off the (very adequate) cold air coming off the coil.

Thanks in advance.

 

Something is wrong. I can't have the A/C blowing out the under the dash when my girlfriend is in the truck. If I do I have to listen to how cold her feet are, I personally wish that the A/C would get colder, but then she would be wearing a winter coat in the middle summer while in the truck.

 

It does sound like it's working correctly. This is how the auto temp control works, it blends warm air with cold to maintain the set temperature. With the manual system you still get heat with the A/C on if you move it away from the full cold setting. The compressor still cycles you just wont feel the cool air. As for the reduced airflow to the drivers foot well, this is designed in to keep your feet from getting too hot since you are forced to keep them there in order to drive.

 

TBird, I agree that when you move the temp selector away from full cold there will be some heat mixed in to moderate the cold air from the AC. That's how every vehicle with AC I've ever owned worked, including my '01 F150, which was easy to adjust. In this case, there's hot air blowing at the passenger's feet at full cold as well as when I have a little heat blended in. I expect full cold from all outlets at full cold setting and moderated temp air at all outlets when I have a moderated temp setting. Instead I get cold air from the dash vents and hot air from the pass foot vent, a little cool air at the driver's foot vent until I have it set about 1/3 of the way from cold to hot, then it starts getting warm at the dash vents. And the dealership expects me to accept that this is how it's designed...

Either there is a design flaw here or there is a control flap not working properly.

 

I would say it sounds like your blender door is stuck open but I can't see how it would just have a problem with the temp to the pass floor board. But there is a problem if its cold there in winter and hot in summer...I am just not familiar enough with the way the ducts are layed out in these trucks to tell you what is stuck open...but I am willing to bet something is!

 

My apologies I misunderstood what you were trying to say. It must be either a problem with the blend door or the vacuum motor attached to it.

 

Sounds like the temperature blend door ain't doing it's thing right. I haven't seen any blend door problems personally yet on the '04+ F150, but that's not to say it can't happen. Sounds like time for a visit to your friendly neighborhood Ford store.

 

If only said friendly neighborhood Ford store didn't blow me off by saying they all do that. Hot air on passenger's feet on all AC settings isn't my idea of proper function. Maybe I'll drive up the road and try another dealership...

My dealership assigns service advisors by VIN, so when we got a new truck, we got a new service team. Both times I've been in for warranty service, I felt like the new advisor was ****ing me around and not taking my complaints seriously. If the old guy was doing the same thing, he did a better job and I never noticed.

Must be something about this town - I bought a new VW last year and have similar problems with the local VW dealer, so I bought the car and have it serviced at a dealership over 40 miles away.

 

Sounds like the dealers in your town feel they can pull this stuff because it's a hefty drive to the next dealer.
