Question about 2005 Chevrolet Silverado
Have speeds 1 thru 5, all work but number 5, on fan switch
This setting pulls the most amperage on the circuit..and may have fried the switch contacts..the other settings use a resistor block to slow the motor down hence less amperage.. check the switch with a tester for continuity(take it out and check seperately) see if high works or not..if so equipted, may be relay assisted also..

If you got heat on all speeds and the blower motor is working properly then you probably need a new HVAC switch.

SOURCE: a/c heater climat control switch
Check the relais module located inside under the rh side of the heather box you can see the connector most of them need to be replaced as they burn out you may need to replace the blower motor as well,high amp draw caused by faulty bearings will overload the blower motor controller

SOURCE: blower fan only works on high
If it is working at all then the relay and fuse is good and the problem is either the little vacuum hose on the back of the control switch panel or the panel itself.

you need a resister found under your air duct by the passenger floor under dash board auto zone sells these for about 25.00 you may as well buy cabin air filters while your at it . 1 of the screws will be a pain to install back into the duct work I left mine out didn,t make a difference . you might have to order it as they are a comman item oh you will need a vacuum to clean up mess from cabin air filters .this is not a hard job .
