Look into the power distribution box under the hood. Look for the a/c (compressor) relay n swap it with another like relay n see if the a/c comes back to life. The relay power contacts get dirty overtime from arcing every time the compressor comes on and the voltage to the clutch gets lower n lower until the a/c clutch can't stay engaged.
