Thanks for the advice guys. Ive made the decision to takle it myself. I have access to a shop where I ca vacuum it and charge it myself. Now, im getting a parts order together, and have a few questions.
Where do I get the foam for the vents? Is this ACM evap/expansion valve combo up to the job?

Do I need a special tool to pull the steering wheel off?
Thanks for all the replies.
