Owners may comment on a condition where cold air may be blowing into the passenger foot area. The air leak has been identified as coming from the joint between the heater cover case and evaporator case and generally located toward the front of the vehicle where the AC module meets the front of dash. The leaks could be found on either side of module.

This condition may be repaired by applying the 3M strip caulk (or equivalent) to the case joint area where air leakage is found.
