2016 frontier 4.0

No ac. Full of freon. Fans don’t turn on. Where is the ac relay? I can’t find anything ac related in fuse box.

Meaning I thought maybe it needed a little 134a, but it was already full. Turns out the ac fans aren’t turning on. Getting no power. Was gonna test ac relay but can’t find it

The fans only come on when the computer says to turn them on. If the A/C load isn't severe enough for the computer to turn the fans on, they won't come on. With a working A/C you can come to a stop, fans are off. Wait a little bit (in hot weather) and the A/C load will build and the fans will start up.

So do NOT assume that the fans are tied directly to the A/C. There are various pressure and temperture switches that also play into the compressor engaging.
