Air conditioning panel/ dash buttons clarification

Recommended Posts

As per picture, I am sure I understand how the buttons are meant to work however my AC doesn't seem to be blowing cold despite the shop saying it's blowing freezing for them when they run it.

 

So I'll just rattle off what I think is what and if I'm wrong someone stop me( I should have done this at the garage..).

 

Pink - Temperature selection and fan speed

Green - All fans/AC OFF

Red - AC on/off

Blue - air flow directional control

Yellow - defrost options

Orange - cabin circulation or draw-in from external vents

When I turn AC on, the white box labelled "Auto" has the green LED above the fan icon come on and the fan speed dial goes to "Hi" setting. Is this intended? I can manually turn the fan speed down, and the AC green LED stays on, but at whatever fan speed, it doesn't seem to get cold to any noticeable point.

 

Also, the orange box..I always assumed with vehicles that if you prefer the temperature outside the cabin, then you have the air draw in from outside. When you like the temperature and want it to remain constant, you switch to cabin circulation.

 

?

 

Are Supra AC units particularly poor at reducing temperature quickly or?

Maybe I'm a bit spoiled but, more than a minute is taking too long to get at least some drop in temperature.

Seems like the system is working as designed.

 

mine cools the car in under 5 mins and when i say cool, i mean really chilly if i want it - something isnt right with yours (are you sure its been gassed correctly)

That's what they tell me.

Previously I tested it on a road trip. AC was on for a good ten minutes and it certainly wasn't chilly.
