Question about 1999 Chevrolet Blazer
If its anything like a 95 model, that unused plug near the blower motor is used when setting the timing on the vehicle. It removes the ignition advance from the distributor. I would be careful about experimenting like that.
To troubleshoot your blower motor, go buy a cheap test light and unplug your motor plug. Connect the test light. Turn on your motor switch. If it lights when connected properly, the motor is bad. If not you have other issues. Could be a relay or resistor module. Just takes a little more troubleshooting.
