Re: Fan speed "3" is gone..

Obviously the parts you replaced were good because you still have the 
same problem. Save the fan switch and now you also know the 3 and 4 
speed relays are alright. It is a simple circuit so I can only 
conclude either a break in the wire (ky) from the 3 speed relay or 
more likely a connector has backed out of the relay panel where you 
insert the relays. Pull relay 3 speed and with a light examine the 
electrical connectors to see if they are pushed and locked all of the 
way up. If needed pull 4 speed relay to compare. There is a tiny tab 
that locks the connecters into the plastic, you may have to bend it 
SLIGHTLY so that the connecter is retained in the block when you 
reinsert the relay. If you have the workshop manual refer to M:18:19. 
It is a little ambiguous so follow relay #12. Use standard electrical 
troubleshooting techniques to isolate the problem.
