Climate Control Issue

tomred · 01-12-2020, 05:30 AM

I have a strange issue with the CC.
I live in Dubai and it's winter hear so temps are nice and I have some time to sort this before it gets HOT.
Basically the CC was working normally, then the other day I got in the car and I had the CC set to about 22C/72F on AUTO and AC on as I always do. However the air coming out was hot and it was about 25C/77F outside. Also the fans were coming on to full like it was desperately trying to heat up the car.
Now the only way to get cool air is to set temp to lowest 18C/64F. If I set it up by just 0.5 degrees it goes back to hot air?

Any ideas. I am guessing there is an inside temp sensor somewhere?

Got the same issue, suspect its the heating and ventilation stepper motor that control the blend flaps..

As time goes on the differential between cabin ambient air temp and the setting of the auto control is no longer sufficient for the cc control module to activate the air temp that you want. So the ambient sensor and module are a little out of sync. Not sure on the actual adjustment process or if you can adjust it. The fsm should direct you. Hope that helps.
