SOURCE: Intermittant hot/cold air from heater

Had the same problem with my Mazda6 awhile back. Took it to the dealer and they found the radiator wasn't holding pressure. They replaced the whole radiator under warranty (WHEW!). Not sure how to check for that kind of thing, but it's a start.

SOURCE: 2004 Chevy Silverado AC is blowing warm air on passenger side.

You have dual zones that are controlled by temperature actuators the passenger side has lost its memory or has gone bad you can put it in self programming by disconnecting the battery for ten minutes then hook it back up start the truck turn the temperature control on but do not touch any other controls let it go thru the self programming for about 6 to 7 minutes then select your temperature you want if it still does not work properly you may have a bad actuator or a bad connection at the actuator

GM 2014 Silverado 2500 climate control blows hot air out of drivers side and cold air out of passengers side

You have a bad transition valve or disconnected vacuum line on said transition valve that moves the blend door open and or closed under the dash. If you have the heat on and heat only goes to driver side and still cold on passenger side, then the problem is at the passenger transition valve.

The ac compressor in my 2006 Chevrolet Silverado turns on and off while parked. It's blows really cold air while driving, but blows hot and cold air while parked. To hot to sit in truck while parked. ...

the problem is not the compressor but the head pressure is to high and the high pressure switch is shutting it off
You say really cold while driving but on/off when stationary
That indicates that the fan in front of the condenser is not working and the high pressure gas is not converting back to liquid
2 possible items to check
fan--fan relay fan relay fuse
and excessive gas in the system
take it to an accredited ac specialist shop and have the pressures checked
At this point I am thinking excessive gas
