    Hello all,

    I have a 1989 Chevy c-1500 with the manual selector (manual cables) for the selection of heater or defrost. I also have the vent selection but rarely use it. My question is on the selector flapper is a geared assembly that every now and again will jump a tooth. Does anyone have a recommendation on fixing this. Thanks
