Read A/C problem not working

Check the rear AC blower fuse in the power distribution box under the hood, there is also a problem on some units where it body harness plugs into the engine compartment harness. And finally(this happened to my Tahoe) the plug at the rear blower motor melted due to a bad motor.

Thank you, turns out there's a cable that is loose in the back where the a/c comes from not sure what it's called . Need to be replace I moved it just a bit and my a/c worked but the cable gets hot not sure if that's normal
