Where is fuse for back ac on a 2002 Tahoe?

the rear a/c unit is made up of an a/c evaporator, a blower motor and if equipped a heater core with blend door. your most likely needing the blower motor to work. check the fuses inside the cab by the drivers left knee area, then the ones located under the hood and the ?drivers? side. usually they are labeled pretty well. the a/c unit itself runs off the same compressor as the front unit. so unless both are not working most likely the fuse for the rear blower motor.
