Air Conditioning problem on 89 300 SEL
The air conditioning in my 89 300 SEL is not very cold. Cool at best! I am taking it in to have Freon put in. The shop says I have to have a "leak check" first. I bought this car, and know the original owner. It has never had any additional Freon added. Is the "leak check" necessary or unnecessary expense?
Any idea what I am looking at cost wise?
