I just purchase 1998 s420. When I got a car a week later I notice that this car has the air conditioning problem so I went to mechanic they told me, the A/C dried out, so they told me to buy a134 fill in. I did that, after I fill one can I heard very laugh noise when compressor kid in, but not noise from the compressor from some where else. be hide head light area.
So i think the cooling is not enough so I add 2 more can I saw a smoke came out of the tank be hide the head light and the liquid just run out at the tank.
What should I do to make the A/C working??????? Please help.
