Oddly, my mpg -- which is already a very-low 19 mpg on the highway regardless of how i drive -- goes DOWN as i increase octane. Normally it's 19 mpg with 87. I tried a few tanks of different octane to see if it helped, and 91 was 17 mpg. 89 was 18 mpg. Same gas station, same weather, same...

Good to know, thanks. Just gathering info on what others have, eg to see if it contributes to wind noise or not.

Is the top of the windshield supposed to be flush? The body shop ford contracted out for my mold issue (see that thread), as well as a wind noise issue, said they noticed that the windshield wasn't flush with the top of the cab. Is this normal or abnormal? Sorry for the low resolution photo --...

Update: i'm curious about you all's thoughts. The third party testing company, the body shop, said they could not find a leak despite 200 gallons of pressure wash spray. Specifically, the windshield and seams seem okay. But they saw that the wires I run through the driver's side gasket (under...

Ha, hard to totally believe :D Your insights and experiences are super valuable, and I've certainly appreciated the help many times! Sure thing; but I'll just reflect that right back... Not sure what to say about level :D Perhaps on the "knowledgeable" side? Either way, when a board like FCIM...

Yep, agreed. Hence saying that it's part of a resistor divider, and that Higher resistance = lower temp, and Lower resistance = higher temp (causing the voltage change in the dividor)

Yep, exactly, you got it now :) "the resistance from the Thermistor, varying by the temp, uses up voltage" One small correction addition: the thermistor is just part of a resistor divider. So it doesn't use up voltage, rather it creates a voltage based on its resistance.

"the only thing controlling it is the (Combined-Humidity/Temp) reading on pin-5" Pin 5 is Gnd. Also temp / humid aren't combined: there are two pins. One pin has temp, the other humidity. "So, Pin 4 is the KEY output to play with (I believe) as this would be the main control full open and close...

Thanks. Yes, I've understood what you wrote as well. FCIM is the control module for this operation. As i think i mentioned in some other posts though, sunload wasn't a contributing factor, because i did tests at night. Also, outside temp wasn't an issue because i did the tests at various...

Yes; that was me. I checked a BUNCH of stuff and had no success. See here: Nope, no success on this yet. The vehicle seems too tightly integrated. There are still a few ideas i'll check out in a couple of weeks; for example, i have some electrical connections that i've broken out from FCIM that...

True...agreed. But it hasn't been cold this winter, and the mold wasn't there last year when i pulled up the trim to check something

Purchased new -- no flood damage that i know of. Perhaps AC, but i thought that would be located somewhere else

Exactly. I have it in writing , with an email printout from one of their warranty heads, saying they're outsourcing specialized jobs related to water leaks, air leaks, and body panel alignment. The dealer mentioned the shop will call them to verify an active repair order and bill Ford.

Update: they couldn't find any leak. They are telling me to go to a 3rd-party company for service -- which is the same thing they told me for the window whistling noise issue. Presumably that company specializes in trim work etc and can find noise and water leaks better. Either way they're...

Yes it disappears. As i slightly open the window the noise also /changes as the window opens. i'm sure it's the window :p

In principle i agree, but just to set expectations for the OP: I think the above statement depends on the specific ranger. I get only 19 mpg highway: hand-calculated with super light foot, level, no wind, 60 mph, unloaded, good oil, proper tire inflation, etc etc. It's terrible mileage for a...

interesting. But mine is certainly the window because I can trace it with the stethoscope...

Turns out it's recent: I just pulled off more of the trim, and felt underneath the floor insulation, in the raised/sloped area under the dash (the part next to the brake pedal). It's moist. So something seems to have been either coming from above, or so much moisture, that it's still wet after a...

No, never. And nobody drives it except myself. Also I have a rubber floormat (removed from this photo to show the mold underneath)

this is a 2021 (march 2021). I'm not sure if there's a seal issue with the windshield, but i can say with 100% confidence there's a seal issue somewhere :D
