Hello everyone. I have a problem with the A/C on my 98 CLK320. Here's the 411.

I turn on the A/C and the compressor engages. After a few minutes, the compressor will disengage and will stop blowing cold air.

The only way I can get the compressor to engage again is to turn off the car and wait for about 30 sec to 1 min. You'll hear a "tick" sound. After that, I can turn on the car and A/C again and the same problem will occur in a few minutes.

What's strange is that even if I turn off the A/C for an hour or more, and turn it on again, the compressor will not engage unless I turn off the car as I described above.

I read in the manual that the EC light will remain ON if refrigirant is low. Mine didn't do that but I took it in to get it checked out anyway. They added some 134a and also told me the pressure was fine.

Any help would be appreciated.

Thanks in advance,
JL
