69 Dodge Polara…318 automatic originally A/C car. Bought it 3 years ago always thought PASSENGER side fresh air vent behind kick panel was broken. Driver side works fine. Took apart yesterday to find passenger side air vent has no vent…just a factory cover over it…but lever under dash and cable are there. See attached photo of removed parts. This surprised me. Is it the “norm” for A/C cars to have fresh air delete on passenger side? And yet have both levers under (steering wheel) dash? And even the passenger cable there not hooked up to anything? Weird…Can I expect it to blow fresh air if I can find a vent for passenger side? I would think so. Anyone have passenger vent laying around they’d like to sell? Sorry, lots of questions…just looking for some info. on this. Thank you….Bob
