I had asked a previous question about the blower knob #5 not working. 1 through 4 blowers work but when I turn it no. 5 nothing comes out. It didn't work in the summer time and it doesn't work in the winter. I got a previous answer to change the no. 5 fuse but I took it Auto Zone and we checked the manual and there's no number 5 fuse. What else can I do?

Thank you

I think I answered your question,I didn't give you enough info.(sorry).I look ed at the scematic and there is 3 fuses that control the blower,#35 in the underhood fuse block,hvac 1 fuse #39 in the rear fuse block and hvac b fuse #36 in the rear fuse block. check these fuses and if they are good go to the blower resistor and check for power in all speeds,if you have power on all speeds it is a blower resistor,if no power on #5 speed trace it back to the control head and see if power is commong out at the switch. post back with any other questions.
