1996 jeep grande cherokee overheats

my 1996 jeep grande cherokee limited 5.2 v8 overheats when i turn the a/c on. it boils out of the the reserve tank when i turn the vehicle off. I replaced the relay, radiator , water pump , serpentine belt , thermostat and the fuse. still does it. I don’t think its the fan clutch. ( it has some tension when I spin it ). Any idea’s, I am lost. can you help!!!!!!!

  1. Is there an electric fan on the front side of the radiator that isn’t coming on when you turn on the A/C?

    Does it not overheat at all while driving around normally without the A/C on?
