First the AC stopped working - it used to blow fuses all the time while I was on a long drive. I was hell of a ride because if the fuse goes out apparently the power windows stop working too :) They installed a circuit breaker but now the compressor is actually not getting power ant more.
Fixing the heater now is most important to me. It stopped working sometime during the last few months - I do not know why.
I am not clear - if the compressor is not working would the heater not work as well? It is blowing, but no heat.
What should I check?
Is the control board under the dash involved in a case when the fan (or whatever blows the air from the heat core) is operating?

Thanks
