Heating Problem

[robin61]

Hi all, Thought I would join this group to see if anyone can help. I have a 21 plate Corolla Hybrid and whenever the weather is damp outside I always have to have the A/C on. If not then the windows mist up very quickly.

Have never had this with any other brand of car i have owned. The car is obviously drawing in moisture from somewhere. All carpets are dry and no leaks etc. from anywhere.

Has anyone else had the same problem and if so did you ever get it resolved. Its been into my local dealer and they say they can't find anything wrong. Very frustrating as to have to have the a/c on all the time if I want this to stop.

Comments would be welcome

 

Thanks All...........

Do you use the air con in conjunction with the heater?

Have a look at the first post of:

Also using dehumidifier bags, and closing the air vents when parking may help absorb some moisture.

Hi and welcome. 
The Toyota Corolla hybrid has very advanced heating and cooling system. 
It is highly recommended to use the system in auto mode with ac always ON. 
Eco/fast function off. Recirculating off. 

Set temperature at 22C° and auto mode ON plus AC ON. 
This is all you need to do once and that’s all.  
If you ever feel too hot or too cold you can readjust temperature settings by 1 or 2 degrees up or down and that’s all. Set and forget is all you need. 
For the moisture in the car you need to cheek boot and spare wheel well. The usual water ingress in any Toyota happens through rear lights clusters. 
Check also carpets on rear foot wells. 
Clean windscreen from inside with clean microfibre cloth and pure water. Clean few times until streak free. 
That’s all.

I second cheak spare wheel well... Water can pool in there...

A lot of this may be that it’s a hybrid. The engine is not running all the time and as Tony says, the system is very advanced so ac on all the time helps to eliminate moisture in the air.
