Why won't blower motor work on 1990 Cadillac brougham?

The blower motor on a 1990 Cadillac Brougham may not work due to several potential issues, including a blown fuse, a faulty blower motor resistor, or a malfunctioning blower motor itself. Additionally, problems with the climate control switch or wiring can also prevent the motor from operating. It's advisable to check the fuses and connections first, and if those are intact, consider testing the motor and resistor for functionality.
