Recently i took my van to a dealer because the knob on the a/c fan melted off it cost 600 dlrs in repairs the hvac knob had melted off also the connector and resistor had burned out . the entire wiring harness was melted together. no fuse blew to prevent his form happening we are not sure what caused this to occur. my concern is that this could have caused a fire in the dash while i was driving resulting in severe injury accident or even death. please contact me if there was a recall i missed or if there is any information as to why this happened. thank you for your time concern chevy owner. *tr
