I haven't had trouble with any. What problems are you having, and I bet one of the guys here will help, but we need to know the symptoms before we can know the cure.

well for one changing fan speeds with the key on will blow a fuse sometimes,, and when you change the controls they don't always work

start  by changing out thr complete ac/heater panel on your dash....
     this panel contains electric and vacum components.

Blower fuses: I would check the wiring to the switch.  Is there an after market radio in the truck?
Controls:  Vacuum leak, or lack of.

I don't know what to tell you on the fan other than start putting a meter to it to find where the load is coming from.
As for the controls, can you tell if anything is actually moving?
