When I push my A/C button on my dash it blinks 6 times and then no A/C. I took it to a shop the compressor the expansion valve the high-pressure valve, had the system evacuated and recharged with the proper amount of freon and oil and still does the same thing flashes 6 times and nothing. The relay and 10 amp fuse replaced as well any help will be appreciated.

The A/C system light blinking is trying to tell you there is a trouble code in the system and it is shut down. You must use a CAN scanner to see what the codes is, or you/we will be just guessing on what the problem is, did the shop scan the system for codes and if so, did they clear the codes once the service was done? You can get a CAN scanner (Controller Area Network) which will work on most cars from Amazon.

Here is a video to show you how:
