Customer Question

Hi Marty,
I'm confused about the location I should use to add freon for my 1997 S500 Mercedes.
I thought I had the right spot, and added some, but the air doesn't blow any cooler.

Hi, the diagram of the charging port location is below. The port is directly below the #15 in the diagram. You might not have added enough refrigerant or there may be a problem with the compressor. I would need to know the system pressures with the a/c running in order to advise you.
