Following a trip to the shop in which an injector was replaced, my AC began fluctuating from from its usual ice cold to barely cool. I drove from Charlotte to Chattanooga last Sunday morning /afternoon and the AC was barely cool, I returned yesterday afternoon/evening during and the AC was ice cold. Today the AC was barely cool while driving around town. I put an AC gauge on it this morning to see if it needed coolant and the gauge fluctuated between yellow and red. Do these symptoms point to anything in particular?

when you turn on the AC, does the front fan come on?
