What is your question?
The a/c is not coming on when I press the switch, it flashes twice and does not start. The manual says this is due to outside conditions ; what are the conditions and how do I rectify them?
How long has your 2012 GMC Sierra 1500 had this problem?

Hello, this indicates a system concern -- testing will be needed to find out what is going on. If the system will not turn on, due to "conditions" or a system failure, it is only something that can be resolved by troubleshooting using appropriate tooling and shop manual materials.
