I have an intermittent problem with my A/C. The dealer has checked it and didn't experience the problem and didn't detect a fault. Last night it did it again! When my A/C is on normal and I move the fan speed up it increases in speed briefly and then it slows down; it will also go up and down in speed even if I don't touch the fan speed control (this happens especially when the fan is on #4 or max). If I switch the A/C to MAX and then back to normal the fan speed control works fine for a short while and then it slows down again. This is most noticable when the A/C is on normal and fan speed is at #4.This is the second summer I've had the car. I didn't experience this last year and have only had it happen twice so far this year. Ths A/C is blowing cold (colder when the fan is working properly). The car is under pre-owned warranty until August 27th. The dealer suggests that I bring it in when I experience the problem - but its so intermittent and has happened when the dealer is closed. What is your advice. Thanks very much for your attention to this.
