There's a resistor pack that's switched in series with the blower motor when you select fan speeds other than high. That resistor pack is probably blown.
(I posted this when Cathy mentioned the problem last time, so I didn't feel the need to repeat myself...)
I'm glad you did, though, because I'd forgotten what you said. Thanks.
By the way, since then the LED clock on my dash has started going black, usually while the engine is still warming up. Is that consistent with your resistor-pack theory?
