Default Air Conditioning only works certain times.

truck is a 2000 with the vg33 and the ac behaves alittle weird. AC works great in the mornings. AC works great at night. AC wont work at all when its actually hot. And I don't mean its not cooling well, I mean it wont even engage the compressor.

I have about 50 mins worth of driving in the mornings, AC works fine the entire time. Ice cold. When I go to leave work I got nothing 99% of the time. Sometimes, but rarely, it will kick in right when its first started but it only runs for 15 secs or so then its back to doing nothing. So its clearly temperature dependent as it will work fine when the temps are cooler.

Im pretty well mechanically inclined, but AC systems aren't my cup of tea. Where do I start?
