Blower motor keeps running when ignition is turned off. where is the blower motor controller located. only way to stop is to pull fuse. came out to a dead battery one morning

It sounds like you may have a malfunctioning component in your heating system that is causing the fan to continue running even when the car is turned off. Pulling fuse 47, which controls the climate control blower and ignition 3 relay, stopped the fan from running but may have also caused other issues in the system. Replacing the fuse may not fix the problem, it may be necessary to have a mechanic diagnose and repair the specific component causing the issue.

The blower motor control processor is going out . The blower motor is controlled electronically .
The fuse for this is located in the rear fuse box , under the box seat . HVAC BLO fuse 40amp

I suspect the blower motor relay. It is in the underhood fuse panel.

read this post on what's causing blower motor to run all the time.

Sounds like the fan control module and/or relay..Need to pull fuse until you get it fix,,or the battery will run down

If you pulled the 10 amp fuse in the I/P fuse block and the blower still worked than the the blower motor module is most likely the problem. It is fed by a 30 amp fus4e in the fuse block under the rear seat. That fuse is always hot and always supply power to the blower motor module. If you pull that fuse and the blower stops than it's pretty likely the blower module is the problem.

The blower module is located near the blower motor. It is usually held in place with 2 screws and will have four or five wires at the connector.

I’m happy to assist further over the phone at https://www.6ya.com/expert/jeremy_d728a59f986299fa

could be a faulty relay , pull relays out one by one and see if stops running

there is a module beside the blower motor under glovebox. this module control fan motor. when these control modules fail one of the issues is that the motor will stay on when ignition is turned off. most common on automatic heating systems.

replace the blower speed control module located near the blower motor
