Hi. I just got my CFE 3 weeks ago and I found a weird behavior on my air-cond. If blower fan is at max, you feel sudden loss of power in a short period like 2 seconds when and only when the car is moving. It seems like happen when the compressor kicks in. It is OK when idling. You can hear the blower fan slows down then run fast again. Anyone experience this? Is this normal?
