Hi and happy holidays/happy new year!
Im a new member so I think initially I listed in the wrong area, so I'm gonna try here. Have my late dad's 93 Park Ave, beautiful emerald green..only has 151 K on it--I've had it 4 years and it has needed nothing but oil (every 5K) tires once and brakes once. But now the heater core went bad, and I by passed it to stop the leak in the summer--but although I'm in Central Cali--Its December it's cold at 6 am! LOL

Have to change it but can't find anything to determine if I have to remove the dash--or not! (Hope not) owever, neither Chilton, nor Haynes, has any detailed step by step instruction other than what to do inside the engine bay and in front of the firewall. And I cannot find ANY YouTube video that is about this generation Park Ave OR Lesabre.-- None. Not even a "cousin" Olds 98 or Pontiac Bonneville. There are some online diagrams and videos that don't show how to get TO the heater core, but only after you've gotten to it.

Any mechanics that may know, or be able to provide step by step help? Or a link to a shop manual or some sort of guide----Much Appreciated!
The damn core was only $30, and I've by passed it so there is no leaking--but wouldn't mind some heat on my way to work!


Thanks in advance for any help!

 

Same post as up in new member intro forum. This is a good question and would like to see the answer(s) myself. Have seen a few questions setting here a decade or so, have to be patient? Or never ask another question, hope solution is out there.
