    Default heater/vents not working, only blowing to floor

    hey guys,
    i recently just got a remote start installed, and now my vents/blowers rent working properly.
    the different speeds and heats are all working but it seems to only be stuck on blowing to the floor. When i turn the knob to change the different settings, i only feel resistance on the floor setting, the rest it just freely turns.

    any ideas on how to do a cheap fix on this?

    What kind of truck do you have and what year is it? (2005 Silverado, 1984 S10, etc etc)?

    Heh I suppose that info could help. Surprised I forgot it. Its a 1995 silvresdo 1500. 5.7L.

    Got it fixed finally though. Turns out the whole control module was fried so I replaced it fully. Seems to be workin nicely so far.
