Believe it or not...I have the exact same problem, I was going to troubleshoot mine today based on the responses to this thread:
http://www.automotiveforums.com/vbul...t=blower+motor
I actually compiled the helpful responses I found into a nice little narrative:
Check for heat coming out the defroster vents. I suspect you are getting heat there, but not out the front vents. If so, the problem is with a vacuum hose. Your heater's vent system runs on engine vacuum to switch between vent, heater, and defrost settings. It is located at a spot under the master cylinder and to the left. Usually the hose dry rots off.
These cars also have had big time Evaporator problems, you may have to remove the switch on the firewall (Inside Engine Compartment), to see if the Evaporator core is possible clogged. When the Evap leaks, all the debris going through the heater box collects on the core, thus no Air Flow. The switch is on the firewall mounted in the blower chamber. It's a unit about 4"x2" with three small mounting screws that controls the variable speeds of the blower motor. It's located immediately left of the blower motor as seen from the engine compartment. There may be a rain guard plastic shield above it that may have to be removed. Removal of this switch gives you access to the heater core/evaporator core for purposes of cleaning out any junk collected in there. Buy A Enviromentally Friendly Degreaser (EG: Simply Green), remove Heater switch, spray Degreaser as best you can towards evap coil, it might be tight but you should be able to see a bit of it.
Let Degreaser sit for say 20 mins, then get out the garden hose and wash it out, hopefully your evap drain isn't clogged, you then should see dirty water coming out the drain, re-check coil should be fairly clean, you may notice a smell so you should run the car with heater on high, it will go away (The Smell Of Course).
Good luck to you...post back if you have any success.
