No air coming out when set to feet...

[JohnnyO]

I've never had much air flow in my floor vents since getting the truck.

Is this a poor design or have I been unknowingly ignoring a warranty claim?

The floor vents are pretty small but also the blend door actuators tend to go bad and it's an expensive fix. I replaced on on my old Sport Trac and it wasn't too but these are a lot of work.

My Ranger is the same way and from the sound of it, it’s normal for this generation to have almost no air at the feet. I’ve not sat in the passenger side to test the floor vent there to see if it’s the same.

What I don’t like is when I remote start it and get in it, the air doesn’t turn on until the key is in the ignition so when I set it on windshield defrost, it hasn’t been doing that while I’m walking up to it after a twelve hour shift. The rear window defrosted does the same and I don’t think the mirrors have a heating element as they take so long to defrost. I also got to feel the transmission do it’s bucking and slipping thing in 20 degree temps until it got warm along with brakes and steering. Overall, I guess they needed to spend more time testing these things in the winter.

Are you setting up remote start as
Climate Control- Auto or Last Setting?
In Auto::
Example if below freezing (32 deg)
The system will automatically go into Max Defrost Mode
So heat to HI and blower motor speed will ramp up as the engine temp increases,
Rear Window And Side Mirror heat will also kick on automatically.
The only time I use remote start is in the winter and catching employee bus to the employee lot - within 15 minutes- cabin is warm and all windows and mirrors are clear - even with recent below average temperatures of below zero

I think you have it set up as last setting, might try changing to auto

I’ve got manual controls so I have to make sure I set it to defrost when I get to the parking lot at work. When I get in it after remote starting it though no air is moving through the vents until I turn the key regardless if it’s set to defrost or any other vent setting.

Sorry as I am not sure of this: But borrowed from another related thread on the subject.

Even Elect Manual Control, should have this setting for an option.
Ford does not give much detailed information on how the system operates, but in remote start operation - (Auto-Setting) for remote start (Below) should automatically turn on the HVAC to a setting of 72 Deg, if the outside air temp is below (?) exact temp unknown, I am guessing around 32 deg it automatically selects Max Defrost which also automatically turns on the Rear Window Heat and Mirror Heat. Note in Max Defrost the Temp will be automatically driven to HI and blower speed to max once the engine temp has risen.
If above 32 deg, the system will automatically set to 72 deg

One ignition is cycled to on - the system reverts back to your personal settings - (Last Settings)

I could be WRONG here, but it would be worth a look as the Auto setting here needs to be set.

Copy & Paste from another thread.

I took some pics of the settings for the group. In the cluster menu it’s under vehicle settings > remote start > climate control. In there, the choice is auto (ac or heat will run to max if needed to cool or heat cabin) or last settings (it’ll run where you last left the climate).

Obviously this only applies to trucks with factory remote start (key fob), not FordPass only remote start. However, on a truck with factory remote start, starting with FordPass will net the same results and same settings should apply:

Just went out to my truck, I never thought to check in the settings there. Changed it from auto to last settings so hopefully that will solve that issue for me. Thank you for that!

I thought I had the dreaded airbox problem.
So, I did some testing.
When In auto and heat mode then the air flow does come out of the driver's lower vent. If you park the truck and get out to feel the vent you will feel airflow behind the brake pedal almost next to the firewall. The passenger's side discharge feels to be more airflow than the drivers.
I noticed that the design of the driver's vent is elongated with several small openings. So, there is not as a significant amount airflow from just one area like the passenger's side.

I've compensated by setting the driver's temperature setting to 75 and passenger's to around 72 when in auto mode for a dual temperature system.

We started out the other morning and my wife complained about cold air blowing on her feet instead of warm. My heart sank as I thought I was starting to have heater problems. But then I looked up, she had the temp set on 66.

 

[fob63]

To highlight operation of the doors.
In Heat operation they open
In AC Operation they close

These PID's are from my Autel Scanner, I do not believe Forscan will display these Pids
Yet - Anyway

Notes: For T/Shoot
Mode Door Position: (Normal Readings as Follows)
Defrost = 100%
Panel = 0%
Floor = 50%
Blend - Panel/Floor = 25%

Left / Right Blend Door (This is the Temp Actuator/ Door) Position, this will check max travel open and closed.
Any selected temp in between the (percent) will vary.
Hi (Heat) = 0%
Lo (Cold) = 100%

Left Discharge Panel Temp / Left Discharge Floor Temp
These temps will vary but should be close to each other, if mode is placed in Blend (Panel/Floor) if you wait about 5 minutes or so the temps should be near equal.

External Amb Temp - Should match OAT Temp, using your phone etc.

Internal Amb Temp - This is the Temp/Humidity Sensor, this reading will read high and or low, if just sitting still as the heat/cold air is rising up from the floor vents through the dash.

Which Autel Scanner did you purchase?

Which Autel Scanner did you purchase?

It is a MS906TS, I have had it for about 7 years , bought it to replace my OTC Gen that could not be updated anymore.
It’s probably a little cheaper now as I paid 1500 for it when new.

Did small ops check just for curiosity.
OAT = 5 Deg F
Dual Auto Set to 72 Deg

Initial start - Auto Mode moved to Defrost Vents
After warmed up - Auto Mode moved to the Floor, with a small amount still being pushed out through the defrost vents and the 2 (side of the dash) demisters.

Strong Air Flow both Floor Vents and with Digital Thermometer:
Measured 110 Deg at Driver's Floor by brake pedal.
Measured 120 Deg at Passenger Floor

The reason for the passenger side to be warmer is due to the way the system operates.
The main feedback temperature reading is at the Temp Humidity Sensor, it will use whatever means it takes to get a balanced FULL CABIN temperature to whatever you have selected (in my case 72 deg)

Note: You will get different results Sitting at Idle vs Driving, as with driving you have the forced airflow from the Air Inlet Door to help circulate the air.
Sitting at idle, the heat will just rise on the driver's side, it will rise up to the Temp Humidity Sensor and provide a Hotter result.

Measured 73 Deg at the (Humidity Temp Sensor) Inlet by the Ignition Switch
This is the small little vent beside the Push Button Start Switch

Now mine is a 2022, so as far as I know I have the upgraded HVAC Box.
But I have been trying to understand why some complain about low airflow or cold feet.
Possibly the Older HVAC box design??

In any case, one should be able to set the heat to HI and blower to Max Speed and set the mode to the Floor and you should be getting a strong airflow on both sides and have heat at about 160 Degrees or higher- IF all is working normally and engine temp is about 195 (Normal Operating Temp)

This test forces the system to operate with Temp Doors (Full Open) so you are getting all air off of the Heater Core)
This would be an alternate way to test if you do not have the ability to use a scanner capable of displaying the proper PID's.

As I have stated before, my feet get HOT, and I find myself dialing the Temp Down to around 65 or so to get comfortable feet or I move it to Defrost Only

 

[TechEditor]

On the 5G Rangers, the driver vent is directly above the feet, not off to the right side like the 4G rangers and they don't blow nearly as much air as the 4G rangers. Upside is the dash vents blow considerably more air than the 4G ever did..

 

[ppfd]

Glad I'm not the only one to have nearly no floor heat.
My "clicking" is getting more obvious, guess I'll have to get it looked at.

So I followed the instructions posted by Airline Tech and switch mine from auto to last settings in the cluster screen and have seen a much better improvement in clearing the windshield while remote starting. Another affect that I’ve not expected, I can now feel air blowing at my feet on half fan speed but that could be a placebo affect so perhaps some other members could try it and let us know?
