When you start the vehicle it makes a clicking noise like a woodpecker that has consumed about 3....5 hour energy drinks. This sounds for approx 35-45 secs. after which you have no control over you heat or AC. I was told it has something to do with fans etc. AC may work for about 25 mins in the summer then the heat comes on all of a sudden.

I was also told that the part costs around $60-$75 but the labor is approx. $350 plus

Its not a good thing when your ac is not working properly in this case one of us is a bit warm and the other is a Little cool. Both climate controls are down to 60 degrees drivers side luke warm passenger side may be 75 degrees.
