try recharging the ac, you can do it yourself its very simple(shouldnt be any different from a honda)
and the normal operating temperature is straight up, so no worries, only if it gets there a little to quickly as ive said very recently, then yoru water pump impeller may be on its way out(did you replace ur water pump with plastic impeller or metal impeller?)
and if you push the switch an dit makes a sound, sounds like the motor is spinning but its not moving the track, you'd need to remove hte door panel and daignose
