AC stopped working suddenly. Both front and rear.

Ran into the store and when I came back out the air never got cold. The blower is working. It was ice cold earlier today. Same thing in the back. I checked any fuse that looked like it was related to the system and everything looks good. Has anyone run into this problem before? Any ideas?

If the blowers are working and no fuses blown, Maybe a Freon leak?

Start with the easy stuff.

Is the compressor engaging?

If so, can you see refrigerant bubbling through the sight glass?

Are the blower motors running?

Possibly an AC compressor relay?
I had a similar problem years ago on a gx470.
Drove to the store and everything was fine, get back in and No AC, just outside temp air.
$7 relay from Napa.

I’ll check it out. Any idea how to find the relay location? I’m not seeing any diagrams when I google.

I’ll check my trucks fuse box shortly and report back. Should be labeled “ac comp” in the fuse box.
