To remove the heater core the air conditioner will need to be to be vacuumed down and recharge, here is a guide for that.

Here is a guide and some diagrams (below) for your car. This will take some time but you can save a ton of cash doing it yourself.

Disconnected the battery as well as drain the coolant. When you are done refill the coolant and recharge the air. I like to put the car on jacks to raise it up a bit for this job fyi.

Please let us know if you need anything else to get the problem fixed.

Cheers, Ken
