A/C was working, just not cool. Took into mechanic to charge. They charged and said everything was working fine. Picked it up and no ac. The fan blows air through the vents, but the ac compressor isn't running. Could it be a fuse or something else?

When dash starts to flicker the compass shorts out and the ac stops working, parking assistant is also affected sometimes headlights short out too but when I turn high beam off and on it stays on
