When I turn on the air conditioner or heater I have a humming noise coming from motor or the fan. What part do I need to replace. It did this two years ago. He said; There was a switch or something else I think. But I could have misunderstood him. Eventually when I cut it on it will not blow or not come on. I have a Dodge/caravan 2002.
