Some customer comments about windshield condensation only during periods of high humidity and high heat have been received.
This condition is caused by air-conditioning cold air leakage through voids and cracks in the upper panel of the defroster duct. These voids and cracks have been sealed on vehicles starting with the 1988 production.
This condition can be improved on vehicles prior to the 1988 production by using either thumb grade sealer, strip caulk, body sealer and/or duct tape to seal any and all voids and cracks in the upper panel of the defroster duct.
Use existing labor operations and time.
