My heat works intermittently. It does not turn-on on command. Only at random times I will hear the fans blowing.Once its on most of the time its good until I turn the car off. Its the same with a/c. The temperature is fine (when it decides to kick-in)I have checked fuses and switches everything seems to be in order. I am not sure where to begin.

Are you referring to the blower intermittently not working?

The next time it's not working, access the blower motor under the dash on the passenger side and rap it with a screwdriver handle. If it starts then, replace the blower motor.
