Ac doesn’t turn on, no Freon leak, has enough, have bypassed low pressure switch on accumulator, no high pressure switch located-(have checked around condenser and high side lines-this is a dual cooling unit. No codes, ac switch does light up when turned on and both blowers are working-could the three cooling fan relays have anything to do with activating the compressor? I did notice that the cooling fan motors do not speed up when turning on ac, and also engine temperature is running right where it should be, at 210 degrees, never overheats
