2010 Chevy 4x4 Z71 package. 176000 miles, tires good, new battery, Runs n drives great, some body dents, not pretty but that don't hurt the way it runs n drives. Either the heater motor is bad or the switch connections are not making contact it don't blow. Bought it to pull a trailer, got a bigger trailer then expected n so I got a 3/4 ton. It will be for sale untill Wed. Then its gone we're moving. Thanks
