Heater/AC Will not turn on
As the title says,
The heater/AC will not turn on, there is no lights that turn on or anything.
Recently my dash stopped working then the next day it started working again so I believe it may be a control module failing.

This is going to sound really dumb, it was dumb on my part, but I know a little bit more about my vehicle now.
When my dash went out for that one day. I took the driver side panel off that's underneath the dash/steering wheel, and somehow I broke that cable shoe that is underneath there. The cable shoe makes the electronics run in parallel according to a pdf I found. When I opened it back up the one said that snapped has one wire plugged into it and it was to the heating/ac. Currently duct tape is holding it together while the $2.50 part comes in.
tl:dr I'm an idiot

haha actually you should be happy you discovered what the issue was. something like that can make you throw lots and lots of parts and money on you car because its the last thing somebody suspects. I'd say your smart for figuring it out.

Otherwise one should always check that the system is fully gassed. There is a pressure temp switch under the condenser that shuts down the whole system if refrigerant is lost to protect the compressor. You can't diagnose HVAC issues without full pressure in the system.
