Hi,
Oftentimes, the A/C won't turn on simply because it is low on Freon/charge. There is a low-pressure switch that will prevent it from operating once pressure reaches a threshold.
If this is something that just started after winter, the first thing I would suggest is to try recharging the system. Take a look through this link. It explains how to charge the system.

Also, here is a link that explains the most common causes of an A/C system not working:

Let me know what you find or if you have other questions.
Take care,
Joe
