Rear heat

[SpareParts]

Im pretty sure the rear blower motor resistor might be the problem but i'll ask anyway.
The rear blower motor blows very little air out the vents. Is there any setting i don't know about that adjusts the speed of the motor?

The rear controls should adjust speed, and the front ones too with 'rear' button on...
although they can become de-synced with front controls if the rear controls get used, but will re-sync with an off/on press of the 'rear' button.

Think you're right on the blower module..
