Hello everyone,

I have a 1999 Audi A4 Quatro, 1.8 turbo 5-speed.
My climate control seems very confused. The outdoor tempeture is all over the place and in the hot summer months reads below zero which causes the car to blow heat most of the time. On the other hand in the winter months there are times when it only throws air-conditioning. Any suggestions what might be causing this?

 

you should take this to the b5 a4 forum

 

It is radiautor issue which is my experienced say.Try to check this then you will come to know what is the matter behind that it gives you wrong climate control.
