I am not able to pull up your original problem but will tell you how to get compressor clutch to kick in.
Set the air to go on. The oblong black tank has a electric plug going to the low pressure switch. Get a electric wire about the same thickness and make a U shape. When you have your freon can connected at the fill port around the black tank, inset the U shaped wire into the socket you took off and it will bypass the lowpressure switch. Fill the system with the 1 can of Freon. Close off the Freon, remove the jumper from the bypass, and see if the compressor starts to "cycle". Have some type of gauge and measure the amount of charge in the system. Too much is not good either. Coming into your case after you have done things I am assuming the system was not fully charged. If everything else is working properly then only a low charge would prevent the compressor from engaging.

Lost blower motor and A/C compressor at same time, the 60amp fuse in distribution box is good, was adding frefrigerant to system then noticed compressor not running and no blower MTR either

you have probably put in too much gas and the compressor has shut down due to the high head pressure switch activation
ac systems only have a set amount of gas required to operate and more is not better
if you had to add gas then there is a leak in the system
most systems need the blower to be switched on to operate the ac compressor , check the blower fuse as it is separate to the 60 amp fuse
have an accredited ac specialist shop check the ac for leaks and correct pressure

Vt aircon compressor wont engage

check the freon, if there isn't enough it won't engage, could also be the low pressure switch or a fuse.

Ac compressor clutch will not engage on my 98 yukon.

The most common cause of no clutch engagement is a low state of refrigerant charge in the system. Have a set of AC pressure gauges hooked up and bypass the compressor cycling switch and check the pressure on the low side charging port, you show shop 28-32 PSI at idle.

My air condition is not working

first check your fuses and any relays sometimes you have multible relays that are the same in a fuse box that you can switch around but i would bet you have a leak either in your compressor or in your line if the clutch is not kicking on and off or running all the time when you turn it on thats because your freon has leaked out the system is sealed freon does not go bad if there is no pressure in the system it will just blow warm air your question is vague so if your blower is not blowing bad blower motor or a fuse if warm not getting cold your system has a leak if you have not broke the system you can try stop leak 2 cans to seal a leaky compressor compressor could be bad if it wont spin noisy clutch could be bad need new compressor but if a leak after stop leak add the right amount or r-134a 2 to 3 cans if the compressor kicks on on the first can of stop leak or freon your system did leak down and you hope the stop leak fixes it but first check all your lines are tight and that the freon is not leaking from the high or low pressure ports the valve can leak sometimes make sure your caps are on take some spit after you add freon back into your system see if your spit blows a bubble if it does replace or tighten the valve. a few things to check start with power fuses then add a can of freon if you have power now clutch engagement if you add and kicks on there is the reason a leaky system it will all leak back out in a day or several days... thats why you can add the stop leak things you can try or take it to the shop and pay someone some $$$$$
