Volks, I have been reading the archives and it seems that the cause of cold air drafts near the driver's and passenger's legs is one or more factors: 1. kinked or tightly bent control cable not allowing vent flaps to close tight 2. fresh air vent flaps in heater/vent housing not sealing shut due to decomposition of foam seals 3. detached fresh air vent ducts at attachment point to heater/vent housing One solution suggested in the archives was to just block the fresh air intake behind the upper radiator grill. My questions are: 1 If there is not fresh air coming into the heater/vent housing will this cause a problem when using the heat? Like, will the heat exchanger over heat the unit somehow? 2 What will be missed if the fresh air vent is blocked off... I never use it anyway. Thanks, Bill |
