AC light flickering then dull air

You can check the relay by just using the horn relay. Easy swap.

 

It's the "under cover swing case"

It's solid. plastic box, but pretty sturdy. I just use it for emergency tools and shit

 

OP, I’m going through the same thing down here in Houston. See this thread - the blinking light could be about 10 things . I posted at the end. I’ve done almost everything and nothing has fixed it. Next up is the compressor itself. Do you know if the dealer replaced your compressor and/or clutch?

Not entirely sure. But I need to call them today, so I'll ask and report back
