  • Oh my my my, how little you understand about vehicle environmental controls.

    I just had the opportunity of riding with a neighbor today, his heat and air conditioning work perfectly, but nothing he did would defog his windshield. The ventilation direction controls are apparently faulty on his SUV.

    Why? Because the controls that direct the ventilation flaps are controlled with vacuum lines and multi-direction vacuum control dials. Any one vacuum line or vacuum control dial out, well guess what, air goes to your feet, not the windshield, even if that’s where he set the dial.

    Either hot or cold dry air can help defrost/defog the windshield, but the air has to be routed to the windshield first, not a faulty control that routes it down to your feet…

    There’s more than the switches at play, there’s heat, cold, thermistor controlled A/C, and vacuum operated ventilation flaps that actually direct the airflow.

    One faulty vacuum line means the difference whether the airflow goes towards the windshield or towards your feet.

    Please learn at least some of the complexities of vehicles before assuming a damn thing.




  • I do think we’re talking from different generations here, and under the assumption everything even works. Yes, it is wonderful when everything works correctly, but even in that case, older vehicles had separate controls for the vents, the heat, and the air conditioning.

    We got a '96 Sonoma, missing the entire right side of the dashboard, so no glove box, no blower motor, and half the missing ventilation system is duct taped over. Thanks to the previous but now deceased owner. :(

    But at least the windows roll down in the heat of the day, and at least some of the ventilation system gives us heat in the cold when the vents are set for open air.

    Yes we’re driving what most would call a shitbox, but it’s reliable at least.

    I’d try to fix the dashboard shit, but that would probably cost more than the truck itself. So, back to simple brain mode…

    • FROST: Warm up the engine, even if the AC worked, like why? Just warm it up a bit and drive…
    • FOG: Wish the AC worked, but at least the windows roll down…

  • None of that stuff works when you inherited a truck that’s missing the blower motor, entire passenger side dashboard, and all relevant passenger side ventilation ducts.

    Yes it’s a shitbox, but otherwise runs great. Just no luxuries, no air conditioning, due to no blower motor or half the ventilation system. Also the heat only works while driving, also because no blower motor.

    At least it’s otherwise reliable, plus also has manual roll down/up windows.


  • Long story short, AC is for drying air, not just cooling it.

    No shit, that’s my entire point.

    Not everybody has fully working AI based environmental controls, some of us from Pepperidge Farms remembers when the controls were separate and not exactly automated the way lazy fucks expect these days…



  • Well I take it we’re not in your state or country. Mississippi here, we no longer have vehicle inspections. And this is respected even in other states that do require vehicle inspections. They’re like yeah fuckit, half the windshield is cracked, but it’s from Mississippi, so nothing Louisiana can do.

    Down here, we’re half-professional rednecks that try our best to keep our own vehicles running. As long as it starts, runs, stops, shifts gears, steers, and has all the critical lights working, it’s fine.

    Hood, trunk, windshield, front grill, rear bumper, doors, heat, air conditioning, etc luxuries are all optional here. As long as it runs, stops, and steers is basically what all Mississippi cares about, plus lights at night. And other states have to observe our very lax vehicle requirements too.

    I’m still working on some of the finer things, like it needs a horn, but generally speaking the truck runs pretty damn good to be 30 years old.


  • deFROST != deFOG

    • deFROSTer is meant to melt frost, ice and snow off the windshield, uses heater.
    • deFOGger is meant to dry fog off your windshield on hot humid days, uses air conditioner.

    I’m starting to gather that most people don’t have any clue how to properly use their environmental controls.
