Today I drove to eat breakfast, came back home and about three hours later was going to run some errands and my battery was completely dead. I went and bought and new yellow top optima and after installing it my A/C fan will not stop blowing in high. Everything else about the a/c works just like it's supposed to except for the fan speed. The bars on the screen go up and down with the adjustment bar but I have zero change in fan speed. Only max A/c blows a little harder. HELP!
