My Bunk A/C not working at all no air

The front ac is probably cutting off to defrost the back coil. U need to diagnose why that blowers not working. Best waynto diagnose that is with a multi meter. First check the fuses, then check that power is going to the blower, low speed will be only a few volts, high will be full system voltage (12-14). If ur not getting power to the blower check for 12v to the blower speed control resistor (i forget its proper name but its the box the blower is plugged into). If u have voltage to that but not from that then either the control on the wall is broke or the speed resistor is broke. Make sure u have voltge on both sides the sleeper blower fuse dont just look at it.
