Good day, I have a very weird and sad problem with my ac and I have to try to get it fixed before Sunday, problem started after changing my engine, my ac stopped working, I was told it was the compressor, thought this hot Texas summer I changed my compressor 3 times, come to later find out I had a leak in my condenser, I had to change that my self because I didnt want to waste any more money than I already have, when I changed it everything went well, I had no more leaks and my system help the Freon well, I plugged in the ac pressure switch which was tested and had electricity present in it but my ecu still reads that I have no pressure, I did a little research and found out the ecu won’t turn on the compressor until it reads that it has pressure which it does because I used a Freon system to check, please help if there is any way I can bypass this please it’s hot as hell and I have 2 more days before I go to my college campus.

Did you mean to post this in the W206 forum? I'm guessing not if you've had to do an engine swap.

But if you do have a W206 C-Class it will still be under warranty, take the car back to your MB dealership and get them to fix it.
