Mazda blower motor only works on high mode?

This problem is very common faced on many other car models too.
As per Mazda protege car problem.


The problem you are experiencing is due to a faulty blower resistor. The resistor is located behind the glove box. Remove the glove box for access.

This will help.

Thanks.
