93 Roadmaster auto climate control
The blower motor isn't working. The fan works (adding remote power), the relay checks out, the resistor block seems to be okay, and what appears to be the problem is no signal coming from the automatic climate control for the fan speeds. Only gets 0.5V at the blower motor connection.
I know these climate control modules have a self-diagnostic capability. Anyone know how to look into this to see if the blower motor circuit is working properly?
