1996 Deville NS Air Conditioning Compressor Replacement

Recommended Posts

Hello

My air conditioning system compressor is failing - very noisy and cabin temperatures are increasing. How difficult is it to replace the AC compressor? I work in the air conditioning industry so I am familar with handling refrigerants, system evacuation and refrigerant recharging. I am asking how difficult it is to remove the existing compressor and replace it with a new compressor. Does it require dropping the engine cradle? I hane the Helm's manual, but could not locate the air conditioning unit compressor remove and replace procedure.

Any help would be greatly appreciated!

For the 1997 model year Seville/Eldorado, you must remove the right front wheel (!!!), the serpentine belt, and a couple of spash shields to get the A/C compressor in and out. See 1997 shop manual page 1B-21.

Here is my thread when I replaced my AC compressor in my 96 Deville. If you look at the top of page 2 you can see what the view looks like through the passenger wheel well inspection cover, you get a clear view of the compressor, Mike

Thanks for the quick replies. It doesn't look to be too difficult. When I get to it, I will let you know how things went and hopefully get some pictures for this forum.

Thanks again,

Mark

Mark, when you get into it, Kevin (KHE) is our AC expert, he helped me bigtime, Mike

If it turns out you need a hub bearing pulley assembly and clutch plate for your compressor, I'll have one available here shortly that is only 6 months old - like new with very low low miles.
