This might seem like a stupid question but I have no reference whatsoever, so I´ll give it a shot.
I just thought of something I witnessed last year before I stored the car for the winter.
When I was driving in the evening I had the top down and the heater on and the fan on full speed. I noticed that the power windows were going very slowly and saw that the voltmeter just under 11 volts instead of the usual 14,5.
Obviously the fan puts a lot of drag on the system as flipping the switch from position 1 to 3 will make the voltmeters needle jump back and forth.
Is that normal or is there too much resistance somewhere? Anyone else witness that on their cars?
