no air blowing heat/ac
I can't figure out why I'm getting no air.
Things I have checked/done so far:
1. I properly bled the coolant system according to service manual. done it 3 times.
2. Fuse(s) is good.
3. No hoes are kinked.
3. Checked the Air Mix motor which controls the H20 valve position and moving it by hand to either position to see if I get hot air, but nothing happened.
4. when I turn on the fan on the cable which hooks up to the Air mix motor does not move at all.
I don't know what else to check for.

more often than not, the blower transistors take a shit. to verifty, jump the power and ground on the blower transistor connector. with the key on, engine off, blower fan should come on. this means the transistor is not grounding and you verified power and ground ckts are okay due to the blower fan coming on
Mine ended up being both.

ok fellas - my fan blower is totally dead too and I followed the instructions here - VERY HELPFUL but
a) Confirmed my blower motor works fine when I pull it out and apply 12 volts - runs perfect
b) Replaced the transistor with another unit and still nothing.
My lights go up and down when I push the switch but no clicks, no relay, nothing. Is there any specific fuses I should check????
P.S. I even replaced the dash temp control unit today as a last resort and still nothing........grrrrrrrrrrrrrrr!!! help!
