No Driver’s side floor heat

[RedlandRanger]

As mentioned elsewhere, a comprehensive test drive might have curbed some of the criticisms.
The last thing on my mind, in the middle of summer was checking the heater controls but it is what it is. I’ll live with it.

I've not noticed any issues, but someone else mentioned that it was better if it was not on auto. Has anyone tried it in manual mode and seen if it is better?

That was me... if it’s real cold. I leave auto off. Got the right combo. Raise temp to 76 or so, redirect to defrost if you are in a hurry or redirect which vents you want and turn fan higher. Works. Then you can lower it if needed or put it back to auto. OR, if you have remote start, start it early. But I never think about it till I walk out the door and realize it’s cold as a witches.... well....you know.

Regarding Auto HVAC: If it behaves the same as A/C, the outgoing air is going to be your set temp (let's say 76F) rather than as hot as the system can make it (let's say 90F). This may appear to be air that's not very hot. Of course this says nothing about the volume of air moving.

I guess that’s another pet peeve of mind. I don’t care for Auto, I hate the max blowing to get it to whatever temp.

Phil, I call BS. This "heat" discussion is the same as the "A/C" discussion we've had this past summer. Bottom line, Ranger did a poor job at providing suitable air flow at the feet of the driver. We don't care about blower noise. We just want to send hot or cold air to the feet, when nessassary.

This would mean EVERYONE has the same issue. This is not the case.

I have zero issues with the flow or volume of air.

That means it is not a design issue.

For those of suspicious that the HVAC system was just thrown together. There are specific testing requirements that have to be met. A rigorous test procedure is required. The test vehicles are instrumented with an array of thermocouples that are placed at key positions of the driver and passenger...There may be up to 200 or more on a vehicle. The thermocouples are connect to a data logger as the amount of collected data cannot be done manually like the "old" days. The vehicle is soaked in the cold room to -20°F. on chassis dyno rolls. The vehicle is started and driven through a set cycle duplicating cold weather driving. Data is recorded at a interval of 2 to three minutes until the cab achieves a program specific temperature...likely around 72°F. Analysis is then performed to ensure that the vehicle meets the requirements. There are also subjective drives to assess heater performance from the customer perspective. If the vehicle does not meet the requirements, and it is determined by the program to release for production, a Deviation must be initiated and signed off by the top level engineers in Light Truck Engineering. Few deviations are ever processed as the directives are to fix the problem, not deviate.. So the take away is that the Ranger meets the requirements. By the way, Air Flow is not a metric given much credence which is the metric of this thread. Temperature vs Time is part of the analysis.

It has been a contentious customer complaint for most of my Ford career about customer expectations of A/C and heater performance.

Temperature vs Time is part of the analysis.

Stoplights and Auto A/C seem to be two things that I spend a lot of driving time reverse- and re-engineering.

Consider this scenario: cabin temp is 30F, requested temp is 72F.

• Current program says set the blowing air temp to 72F and crank the blower to max. Obviously this works and meets the temp/time target
• However, I've always thought it would be a lot less noise to set the blowing air temp to 90F/max possible, and NOT crank the fan to max until it meets the target temp.

(this wasn't a question or even a complaint, just musing)

As a Canadian though, you dress for the weather outside. kinda smart thing to do if you find yourself removed from the creature comforts of a heated vehicle for whatever reason, so in regards to that, i'm not expecting as much from it as some others may be.

THIS. Originally from Florida but have lived near Seattle for 10+ years now and I learned about this concept pretty quickly. I usually use remote start to help clear the windows but then as soon as I get in I crank the heat WAY down because I'm also dressed for the elements.

Hi Dan,

Setting the temp higher does nothing. There is no "hurry function" as it takes the same amount of time to achieve a set temperature regardless of the setting. My wife turns the heat up to 90°F when cold...takes the same amount of time to warm up the house as if she set the thermostat to 72°F

Women do not understand how a thermostat works, I’m convinced of that.

My wife wants the stat at 72 in the summer and 67 in the winter. I’ve given up.

That does not seem to be the case with the auto-temp in the ranger, as the setting on the dash also changes the mix. I'm still trying to figure out all the parameters of how it works. (For example, it also seems like it looks at the coolant temp in the core, and doesn't ramp up the blower until it's warm enough to not blow cold air--in fact, if I decrease the temperature while the truck is still warming up, the fan will sometimes speed up, presumably because the coolant is warm enough for the lower setting? But there's also an electric strip, and that adds another dimension to the equation...)

How can you call BS to Phil's food for thought which I feel is sound?
I've never heard of wanting A/C on my feet even when the temps reach 100.
With the temps close to zero yesterday, my Ranger had no issues keeping me warm while driving 250+ miles in the wind and cold even on the Auto Climate setting.

Most of my driving is in town. Last night I spent an hr on the interstate.
I set the heat on high in manual, floor heat only and set the cab recirculation on.
When the recirculation, timed out? not sure why this automatically shut off but it did.
When it did I felt the heat become more noticeable.
(My wife’s Camry heat works best with the recirculation on, this truck not so much)

The more I think about it I’m heating more cab than I did with my 97 plus I have under seat vents. I may reroute the underseat vents but overall it did a good job and I may need to rethink my position.

 

[FASRanger]

my climate control is confusing me...I just cant get it set right it's between too hot or non defogging the windshield...Girlfriend keeps asking me if i'm cold.. No, just trying to defog the windshield????

 

[kieefer]

I just blocked off the passenger side underseat vent.
I also found a small vacuum hose that fit just right and plugged one side of the drivers side vent with a piece of broom stick.
Routed the hose fwd and wire tied it to the left side of seat.

We’ll see how this works.
Happy Veterans Day
