k inside i turn on the fan nothng happens.. so i went under the hood took white color wire off of fan put a wire to battery n bamm it works.. inside has the tempature wheel, a slide bar from high to loow to heat, what is the little knob to the left.. have no clue.. and is there a specific fuse that ables the fan to work.. helpppppp

[dj kurse 1]

Thts probably for n most likely the knob to the passenger side mirror.

[cwb4eva]

so watt controls things like from floor to dash vents........

[Vanto]

It should be the slide bar you mentioned. Off, Economy, Low, Auto, Hi, Bi-Level, Def. Each one does something different EX:
DEF - Dial @ 85 - Air should be delivered out of the defroster oulets at fixed high blower speed. Some Floor Bleed out
Bilevel - Dial @ 75, Air should be delivered from both A/C and Heater outlets at reduced blower speed, only small portion from defroster
HI - Dial at 65 - Air delivered out A/C Outlets at fixed high blower speed
etc, etc

Check this fuses: (and all while you're there)
2nd from top left - should be 15A

ac fuse has power, i slide the switch n nothn happens

[Vanto]

Let me know if this doesn't look like your fuse box cuz there's another drawing

Usually in gm climate controls the resistors go bad. Its a little thing with different resistors in it that control the power to the fan for different fan speeds. Trace the power back from the fan to see where power stops

id bust on it now, but its dark

is there a way of taking it apart to c?

Resistors r usually in the heater box on top in the engine compartment. G bodys they're super easy 2 change and cheap. Caddys they may be a part of a bigger "computer" type thing on the heater box. The resistors themselves r like curly fries of different shapes. Should be where the fan gets its power from so follow the wire back

k chekd the resistors aka curly things was 4 and everythng looks good i have power coming from main panel atleast in the wire harness that plugs into it.. any other suggestions

Next I would get the wiring diagram from autozones website and start testing wires
