Paulhorner:

Same car, my blower motor is also stuck on Low.

Testing Procedure can be found in these two threads:
1)poor flow

2)blower regulator



connect a DVM to the appropriate wires, and then turn on the car and then proceed to run the blower on Low, AUTO, and High, observe the voltages for each speed.

My voltages were: LOW= 1v ; AUTO= 4.5v ; hIGH= 10.94V

next test, blower bench test: i "bench tested" the blower, by jumpering it directly to the battery and my toupee flew off. so i believe that the blower is ok.

blower current draw:
if u want, check out this thread, posts# 1-7 : Blower regulator or fan - help - W124

in my case, i was told that i need a new regulator by a reputable forum member.

good luck
