Q: heat & air on 2002 BMW 525i

Rookie cbe0621eac06868b3efe0d8d1d3611e23c60d3114864ea2ec19a68cfbd3eebab
blower don't come on ac or heat but ac gets cold and the
heat gets hot
If the blower does not work, it may be the 'final stage' which is a fancy blower motor resistor module, but check the wiring and make sure the switch works ok, because the final stage is about $100, I just replaced one.
