Subject: COLD AIR LEAKING ON
PASSENGER FOOT AREA
Model and Year: 1986/87 CAVALIER WITH A/C
TO: ALL CHEVROLET DEALERS
Some 1986/87 Cavalier 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 core 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 3M strip caulk (or equivalent) to the case joint area where air leakage is found.
