1975 Cadillac Eldorado Convertible » Technical Details » April 2009 New Heater Core
Before reinstalling the air condition system I figured I might as well check the climate control air delivery box under the dash. This box has al the different air doors and the heater core in it. When it was out it was obvious that the heater core had already been leaking slightly. The leak was small enough so it would drip out of the box but it was definitely wet in their. I replaced it with a new heater core, checked all the vacuum solenoids and put everything back together. I also replaced the malfunctioning climate control programmer at the same time.
