DIY: Unlink A/C from Defroster

[SilverGlow]

Why would anyone disconnect A/C to the defroster mechanism?

There is no faster way to remove moisture from the windows and air then using an A/C. If you don't like the coolness, move the temp control to full heat.

This DIY has to be the most idiotic yet! And for what benefit? Surely not for gas savings, as the savings is insignificant....you really need to fill your time doing something useful, productive, and not devoind of logic, and utility.

I have a ScanGauge so I know exactly how much gas I use. When I idle, I use around 0.16-0.21 gallon / hour. With the A/C on, I use around 0.38 gallon / hour (I think it's 0.38. I haven't used the A/C in so long I don't remember).

So I reduce my gas consumption by half or more by cutting out the A/C.

Also, when you have a cold engine, you have no heat. So it's nice to be able to run the defrost without making the inside any colder.

So how does having bone-dry air on the inside of the car, help remove frost and ice on the outside of the windshield? Glass is a moisture barrier.

This mod is for those that benefit from the added raw heat, including the ceramic heating element, to defrost their windshield. You're confusing defogging the inside (windshield air flow w/ AC on) with defrosting the outside (windshield air flow with maximum heat) in this case.

Also, I can give a real-world example: Security guard watching a landslide area in your own personal vehicle on a cold night. I've done that before, had to huddle inside my vehicle to stay warm some nights, '87 Corolla FX I had until I bought my Yaris. Three quarters of a tank pumping weak heat across the windshield, or a quarter-tank if I dealt with frying my face off instead and used cardboard to redirect the heat up on the windshield. My Jeep I took one night ('87 also, Jeep Comanche w/ 4.0l engine) was the same exact way, quarter tank versus three quarters of a tank idling for 8 hours.

Out of curiosity, did you unlink the defroster on the Jeep and Corolla? How did you do it?

I have no problem with the A/C removing moisture from the interior of the car for the first couple of minutes,but once the car is warmed up and windows are clear why do i now need the A/C on when just un A/Ced air from the vents will keep the windows clear. In fact its somewhat of an insult from Toyota to put in this feature as i'm quite capable of pushing the A/C button when i need A/C.
