blower 93 chevy G30 van

The blower on my 93 chevy G30 van stopped working except on high only. I replaced the resistor and the dash switch-- fuses are ok. What else could it be? Van has a/c. Any help would be appreciated.

Any help would be appreciated.[sounds lke an open circuit in the blower motor resistor. this piece is located on the evaporator box in close proximity to the blower motor unit. usually fails due to excessive current draw from the fan motor--plan on a motor too if it is the original/quote]

Thank you for the reply - as I said, I replaced the resistor already-- how do I check the motor. Again, it works on high only - I would think that it would not work at any speed if it is the motor itself. Any other common causes on this ? -- I see from online that it seems to be a very common problem on Chevy vans.
