No summary. Dt.
The blend air door inside of the heater/def plenum broke - casuing extreme heat in cab. Door is not serviceable - requires total heater replacement. See Ford TSB 99-8-8. 7-10 hours labor to fix a 2. 00 part. Ford replaced this abs plactic blend air door with stonger nylon - plenum #f87z-18471-da. This is a known defect yet no announcement is made to owners. This could cost me up to $1000. 00 or more to fix on a 3 year old car. Also this inhibits the ac system to work.
