Default How do I disable A/C on 2018 Camry LE 4 cyl?

I ~hate~ that my A/C compressor runs when I direct air up towards my windshield. I could pop the wiring connector off the compressor for the winter, but I'd rather pull the correct fuse or relay.
er... Where is the related fuse or relay? I'm looking but nothing is jumping out at me.
Any advice?

The fuse for the compressor system is linked to other systems you don't want turned off.

Look in the engine compartment relay boxes for a relay marked. MGC.

TY for your consideration, SuperMod!
But... no such puppy. I suppose the A/C amplifier might have taken over that responsibility.
Under the hood I have these relays:
ST
ST NO.2 (Listed but not installed)
H-LP RH
H-LP LH
WIPER
DRL
FOG FR (Listed but not installed)
EFI-MAIN NO.2
D INJ
VVT
HORN
EFI-MAIN NO.1
WASHER
IG2 NO.1
EFI-MAIN NO.3
DIM
DEF

Could be an integral relay built into another component.

Look the A/C compressor wiring for a connection between the cars wiring harness and actual compressor. Could disconnect the wire to the compressor "clutch.". Note there may be more then wire going to the compressor.

Not sure what this disconnection might do to the rest of the climate system though. The A/C amp monitors the compressor RPM and if no RPM who knows what might happen. At best an indicator light on the climate system may come on, at worst the whole system may shut down.

Very wise, JP, thanks for your thoughts. Just for poops and giggles I'm going to pop the connector off the compressor, and I'll get back here with the results. FINGERS CROSSED!
ps: The whole reason I care is... if I do an errand, and after the A/C runs, when I jump back in the car, the vents blow such high humidity at my glass that I'm instantly fogged until I have a bit of engine heat. Sheesh!

And... shockingly, this didn't go pear-shaped. lol
I pulled the connector and tested the ventilation system; NO PROBLEMS.
Thanks again for your input, JP!
