"This bulletin supersedes bulletin 87-1-13, dated 4188. This bulletin is being revised to add a "T" Labor Operation Number and to correct a call-out in the artwork."




Some 1986 and 1987 Sunbird and Grand Am vehicle 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 core cover 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. (See Figure)

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