QUESTION: 2006 gmc seirra cew-cab 4.8

Answer
from what i can gather from GM's service manual, you should be able to light a test lamp in each of the blower motor positions, if you are not, then there is an issue with the positive voltage feed at the resistor or the resistor itself.  Again just curious if this is the right resistor, if by mistake they gave you the wrong one, you would only have 4 speeds, not five.
