Toyota Automatic Air Con Too Cold!

[MandoDog]

This may sound like a nice problem, but the air conditioning in my Toyota Corolla is too cold. Even if I set it on Auto and the temperature at 28 (the maximum), it simply continues to blow very cold air.

It seems that the only thing the "Auto" feature will control is the mode (which vents are used) and the speed of the fan. Is this right?

I am used to the "Auto" feature also adjusting the actual temperature of the air coming out of the vents (if needed). Just like the good old days when there was a dial to change the temperature from hot to cold.

The result of this is that I need to turn off the air conditioning (go to just Vent) occassionally just to keep from freezing. Drives me crazy.

I tried to get the shop where I bought the car (bought it new) to look at it, but they insist it is working fine. Does this sound right?

Have you a manual setting as well ?

Can you switch from inside to a outside setting ?

Was it a Toyota shop you took it to ?

Have you tried a auto air-con specialist ?

sounds like default or dirty temp sensor, keeps AC compressor running full speed when not providing temp signal

go to another Toyota dealer and ask them to check temp. Set at 18C and measure, set it at 28C and measure

Thanks, seems to be general agreement it should work better than this.

I'll speak with them again, but between my language limitations and the odd symptoms.....

The strangest thing to me is that the temperature gauge must be working as it will control the mode (what vents are open) and speed fo the fan as it cools down. (Starts at high speed fan and slows down as the temperature comes down.) But, it always blows really cold air. So it seems to be a "stranger" problem.

I do use the recycle/outside air switch but it generally has no affect on how cold the air is blowing.

Will let you know how it works out when I try again.

If the recycle/fresh air switch does not change the temp on air in vents, it probably does not work.

Try covering the air inlets, probably under rearend of hood, while fresh air is set. If still blowing in inside vents, not working, either signal, el engine moving flaps or flaps stuck
