My AC went out gradually over a period of a year. When I first noticed it sounded like something was clunking In the dash. I tried doing my own research and can’t really come up with any explanation. My compressor kicks on And off. The pressure gauge says it’s at max pressure and kicks off and goes back down to normal pressure. I replaced the flow sensor an it did nothing. I took her in to my local mechanic and he recharge the system and it worked temporarily, but now back to broken. I’m trying to find where in the dash could the problem be. It’s not the actuator. The evaporator is my next guess or the transfer value. Open to anymore ideas because I’m lost and so are other mechanics. It has refrigerant in system.

Turing A/C on makes the clunk in dash.
