A/C started blowing warm air

So I thought it needed to be charged. Then I realized it was because the A/C clutch wasn't engaging. I got it to engage, checked to see if it needed Freon but it read that it didn't. After I turned A/C off I could never get it to engage again. I checked everything troubleshooting says and nothing. Now it just depends on it's mood I'll try and it will engage. Runs great for 15 minutes and turns off and won't kick back on no matter how many times I try. So maybe it will turn on in four days and then it just repeats. Help!

Hello,

It sounds like the AC compressor clutch coil can be bad which will cause the issue you are describing. To be sure lets check for power down at the compressor when the system is on. here is a guide to help and the air conditioner wiring diagrams so you can see how the system works:
