1994 S320

[ashok]

hello every one,
I have a 94 S320 with 68000.00 miles on it. I turned the fan on and heard two attempts made by the blower and then nothing. I can feel very little air coming in but no volume as such. I have been reading the threads and do suspect the blower or the regulator. I did call on a tech shop and i was told that there is a long fuse in front of the fuse box which of-course i could not identify,I do not know where the blower motor is located, nor do i have a diagram to go by. Nor do i know how to test the motor or the regulator. Please help with a diagram, how to reach and dismantle the blower motor and how to test the motor and the regulator. I just cannot afford to go to any shop much less the dealer.
many,many thanks in advance.
regards,
ashok
