So I finally got my A/C charged and changed to 134. Air is nice and cold but for the life of me, I can't figure out how to open the middle vents without using the EC button (which lets in outside air). Cold air out the all 4 of the side vents and nothing from the middle. Normal?

Other question is now at low idle (with or without the A/C on), the alt light glows but goes out the instant I push the gas even like 1mm. Alternator on the way out? Thanks!!!
