    My heater is not switching between vent, floor, etc. I cheaked some of the vacuum hoses and all looks ok. Anyone know where else to look? Could the selector slider switch thing be dead???

    Is your truck equipped with AC?

    Yes it is. But it doesn't kick the compressor in when I switch it to defrost

    I had one that always blew out of the floor vents. Turned out to be a Bic lighter that had fallen down through a defrost vent and lodged in the door that determines where the air flows. /forums/images/graemlins/blush.gif

    Yes but are the vac lines prone to leak or is there something else I should be looking at?
