The vehicle listed above has a V6.
When I first start my car the A/C does not work. I have to wiggle the A/C Knob to a specific number on the knob which is number 4 and hold it there for a couple of minutes in order for it to turn on. If I release the knob the A/C will turn off. If I leave the A/C knob on number 4 and leave it alone, the AC will turn on after about 5 minutes and will stay on until I turn off the car. Any suggestions? Thanks.
