Hi, everybody

I have an epiphany from 2010. So far, everything has been great. the air conditioner has been blowing warm air for the past couple of days. Please bear with me, as I am by no means an expert. I have read some threads on this forum and most of them mention that the AC compressor clutch relay is faulty. but I'm not sure if this is the problem I have.

When I turn on the air conditioner, I feel and hear something go off, I assume it's the compressor, but there's no cold air, but I hear a hiss coming from the vents when the air conditioner is on, and goes off when the air conditioner is off.

I know I just changed the filter in the cabin. I thought maybe I put it upside down, but I checked and the air flow is directed downwards. interestingly, when I left the filter on, it was a little colder, but not by much.

I checked for any obstructions around the front grille and other air intake areas, and everything is clear.

aside from accounting for this in Honda (which asks for 150 just for diagnostics), what other things should I look for. should I just try to disable the relay to see if it helps?

Thanks.
