Just curious as to what would cause #5 on blower speed not to work but all others work fine.

thanks for any help

The first four speeds are through resistors to reduce the current through the blower motor for reduced speeds, the #5 speed is 12 volts through a relay for full speed. The resistors and relay are all located on the little circuit board attached to the blower motor housing in the passenger footwell. Do a search on the forum for AC blower or some such, I have seen a few posts about this.

Hope this helps,:)

i only have 4 and 5 now, until last week i had 3,4,5 but i lost # 3

wiggle the harness that goes into the motor on the box and see if that helps. also check to see if it gets really hot. i have the same problem w/ mine.
