Does anyone else notice that the passenger air vents seem to have less air flow than the drivers side? I can still feel air blowing out the vent, but it's not near as strong as the driver's side. Just curious if anyone else has this or noticed it. I made sure the vents were pointed straight out, and the flow control knob set to wide-open. I also notice a louder fan noise from the passenger side area behind the dash. Is that normal?
