PhotoJohn Posted September 24, 2016 Share Posted September 24, 2016 I found two similar threads discussing car heaters, but neither gave a definitive answer to my question. In 2011, I bought my first car here; a Toyota Vios J model. Several times during rainy weather, I found myself having to steer with one hand while constantly wiping the windshield with a towel in my other hand. The J model didn't even have air ducts going to the windshield vents. Having enough of that, I finally upgraded to a Honda City with climate control. Over a year now, and my windshield hasn't fogged up at all. I don't think this car has a heater though. At least when I set it to it's highest setting, there's only cool air coming out. But now, for a different reason, I want to change cars again. My present issue is that I'd like to go back to a Toyota Vios again. This time, the G model with Climate Control. I need to know that I won't have the same problem with fogging that I had with the J model. Not really concerned about warm air. I just want a clear windshield in poor weather. So, is a heater really necessary to dry the air, or should any car with Climate Control do the job? Link to comment Share on other sites More sharing options...
ClutchClark Posted September 24, 2016 Share Posted September 24, 2016 The heater will not dry air since hot air holds more moisture. Iys the cold air of an A/C that removes air and is the best nethod to remove moisture from inside of windows. The Air Recirc button will speed the process up even more.

transam Posted September 25, 2016 Share Posted September 25, 2016 At the time my Vigo was top of the range but hasn't got dash vents to work on the screen...Pain in the ass..... Problem being if you get in the ride a bit wet that moisture will evaporate and end up on the screen and takes a while to deal with it......

JaseTheBass Posted September 25, 2016 Share Posted September 25, 2016 If your City hasn't got a heater then it doesn't have climate control.Warm air on the screen is the way to clear the screen as the moisture in the air won't condensate on a warm pane of glass.

cooked Posted September 25, 2016 Share Posted September 25, 2016 A/C cools the air. It also dries the air. Link to comment Share on other sites More sharing options...
PhotoJohn Posted September 25, 2016 Author Share Posted September 25, 2016 OK. Now I'm feeling foolish. I was convinced that I had Climate Control A/C, but now I can't find anything to back that up. Evidently, what I have is Auto A/C that maintains whatever temperature you set it for. I think the salesperson and the lack of english specs. caused my confusion. Still, I can't understand why I'm not experiencing the same problem now with my Honda City as I was with my Toyota Vios. Using A/C in my Vios didn't seem to help at all.

Ace of Pop Posted September 25, 2016 Share Posted September 25, 2016 If You have Climate Control it stays at 25 C in Africa or the North Pole. Wheres a Heater come into the equation on the Controls.?. I cant find it.... Only Heated Rear/Front Window, Mirrors or Seats get a Heater Ref on the facia controls.

The Spivo I have now has screen vents although no heater. On the odd occasion it's has misted up, 'twice? in 7 years' I press the screen button and it clears without heat in a matter of seconds. Woe betide you though if you have anything on the dash as it will blow it off via the roof before it cascades all over you. Link to comment Share on other sites More sharing options...

You can set climate control at a temperature of your choosing. The set temp is displated on a digital read out, on better quality cars there will be 2, one for the passenger side & one for the driver. If the temp. inside the car is higher than the temp. you set (usually the case in Thailand) it will switch on the AC. If the temp in the car is lower than the set temp, it will bring on the heater.

In newer vehicles you can have the heat ON but when you turn on the defroster it kicks the A/C to ON and blows cold air to defrost the front window.

yannic Posted September 25, 2016 Share Posted September 25, 2016 Most likely you had air circulation on that fogs your window on rainy days, any ac prevents this but switching air circulation off helps already Link to comment Share on other sites More sharing options...

In fact, I am reminded to turn off the defrost because the A/C keeps kicking on/off. I am not sure what I can post so please google it. Hondas appear to be the main culprit.
