Why does my a/c keep turning on after I shut it off complet. then turns on itsel
What is your question?
It turns on itself but only to one setting I added frion but didn't change this all happened after I took it thru a car wash it wont stay off and no matter what dials I push it goes right back to its own setting?
With what you describe , adding freon , without proper gauges/equipment , can make things worse. May be an electrical/control issue , or the field coil/clutch may be weak. HINT----- Have someone else turn the A/C on and off while you (with a bright light for best visibility), watch the clutch to determine how well it is engaging-- Do you hear a good 'click' when turned on , or does it appear to slip or is it a little 'jumpy' then leave it on and see if it gets 'jumpy' after a few seconds or minutes (whatever time it normally takes to 'fail').
