redridge: If I interpret your statement correctly, the limit switch is good since the main heater blower runs when a lever is pulled up.

1. The main blower heater switch must be good since the blower turns on when a lever is pulled.
2. Is there a procedure to check the engine compartment relay? I'm assuming my picture shows the relay. Do you know which of the 2 relays is the heater blower relay?
3. Is the fuse on the main blower, or the footwell blowers? If on the main blower, it must be good since the main blower works. If each footwell blower has a fuse, I would think it unlikely, but possible, that they both failed at the same time. If there is one fuse for both footwell blowers, do you know where it's located?
4. I disassembled all the blowers on the car several years ago and lubricated and cleaned them. They haven't been used much, so I suspect the issue is elsewhere. But, I'll check the blowers.
5. Do you know what the resistance should be on the resistor terminals?

Thanks for your replies.
