Heat and A/C Problem
Hey guys, for a while now my truck has been just allowing the blower motor to come on in the highest and second to highest stage. When I switch it to low and the one directly above low it shuts off it seems like. I cannot here the blower motor running. Also sometimes if I have the heat and A/C on for a while the setting above the lowest will work. Please let me know what this is because its kind of annoying. Thanks.

yep, lay upside down on the passenger side floor and look up toward the glove box. Look for a 4 wire plug that goes to a small box about the size of a big isce cube, screwed to the air duct.. Remove it, one of the resistors is burn out on the back side.
