Volkswagen Jetta Year 2002 2.0

Hi, I'm widowed in this forum and I don't know if there is something of this topic and I have been looking at and I haven't seen anything.

Tegno a Volkswagen Jetta and when I turn on the air conditioning does not come out cold air but at the time I begin to accelerate this and cool and connect the compressor, the car carries height.

Thanks and very good pagiana
