blower motor
i've read through other posts, but have not been able to come up with an answer to my problem.
My blower motor stopped working on all speeds, so i checked all of the regular problems such as the fuse, actual motor, resistor, and the brown wire behind the dash. All seem to be in good working order. If i turn the ac on, the ac compressor clicks, and the accumulator will get cold, the driver's side fan even comes on like its suppose to. Don't know what I have done to my multimeter, but it looks like i have to find it to see if the blower is getting any power, but could the resister be blown? running out of options, please help.

Sounds like you're not getting any power to the selector switch (or a dead blower motor but, you said you've tested that soo..).
Even if the resistor(s) have went to the wayside, the blower should/will still work on 'hi' because the resistors are bypassed and the motor is powered from the blower high speed relay (should be located right by the resistors).
If you can't locate your multimeter, a simple 12v lightbulb will tell you the same thing (it's getting power or not).
