Heater blower doesn't work.
I have a 99 F150 and yesterday the blower fan on my heater stopped working. I still have heat and I can change between panel,defrost, etc. I checked the fuse, I think it was 24, and it was fine. Its cold up here in alaska so I would really appreciated some help.

got a trim level to go with that info ?
Does the truck have a manual or EATC HVAC system ?
Do you get any fan movement on any speed ? manual has lo med-lo med and high I think are the position names.
There are 2 fuses with the blower.
Battery Junction box ( engine compartment ) fuse # 105 40 A is for the blower itself.
Central Junction box ( cab ) fuse # 22 is for the coil on the blower relay. The blower relay is with the flasher ( 2 items in one block ) under the dash, around the steering column. PITA to find, but it is there.
Quick test ( after checking the fuses above ) is to pull the blower relay, and jumper the normally open contacts with a wire. Start with the 2 fuses above, then we can move from there.
