I have a 2000 Chevrolet Venture. It has front and rear A/C. Front AC works good, but when I turn on the rear fan, it doesn't always come on. Sometimes I have to leave it on, until it decides to come on all by itself. What can be causing this? Is it possibly an issue with the fan switch, or is it more complicated? I also notice that when the rear fan starts working, the air coming outside the front driver side vents gets cooler.
