Don't know if anyone is still monitoring this thread, I'm having a similar problem (a 2005 Tacoma 2.7L):

My HVAC blower does not blow air on any speed setting though.

I pulled the blower motor and applied 12v directly to the terminals on the
blower motor and it spun up fine. Then I put a voltmeter on the plug itself. It is giving me 12v reading on all speed settings other than off. Thinking this is odd, I put a test bulb on the plug to see if it would light up, and it didn't.

This is telling me that I'm getting voltage to the blower, but no amperage. I checked the fuses for a partially blown (all the 10 amp & 15 amp looked okay to me) but the owners manual doesn't tell me for certain which one controls the blower. However, I'm not having any other electric issues, and in fact when I turn on the A/C the compressor is kicking in even though the blower isn't.

In some respects this sounds like the resistor problem, but in the posts here everyone has said that the blower should work on the highest speed setting, even if the resistor has gone bad. My blower does not work at any speed setting. Could this still be a resistor problem? There was also some mention of a relay - Could I still get 12v on the plug even if the relay is not tripping? If yes, where the heck is the relay for the blower?

I'm really perplexed. Any one have any ideas?
