Hi,
I have a blower motor that will not shut off unless I remove the fuse. I understand there is a relay that does this task but it it an integral part of the heater blower motor assembly? Do I need to change the entire assembly. If so, how much time does it take to remove and replace the blower motor?

Thanks in advance for your answer.

Regards
Ron

BLOWER MOTOR HIGH-SPEED RELAYS
When mode switch is set to HIGH, high-speed relays are energized from CCU center connector pin No. 1 (Orange wire), opening a path to ground, allowing full battery voltage to be applied to motor. High-speed relays are located in blower motor assemblies.
