After having replaced a failed blower motor a couple weeks ago, I found last night that now the Blower doesn’t know how to turn off.
Turned the car of and the blower continued at full speed, turned the car back on and adjusted the fan speed to the off position, but it kept running. Great, the resistor/control module failed again. Pop the hood and pull the 30a fuse and the blower shuts down.
I’m fairly convinced this car had its wiring harness done by a former Lucas employee.
