Heater Blower Motor Replacement
Posted: 12 Jan 2021, 14:28
My blower motor has been acting up recently, takes some time to get up to full speed and squeals a bit in doing so. It's had too many birthdays so replacement is my lock down goal. My plan is to take the dash out, remove the heater box, replace the motor, replace all foam seals and change to a PWM speed controller. I have some questions...
The replacement blower motor is approximately £30 from various suppliers. Brickwerks do a Meyle and a Febi unit, both the same price. Does anyone have any experience of any of these? Is there any particular unit/manufacturer that would be preferred? Has anyone upgraded the blower motor with a more powerful unit?
I have read through CovKids thread on a PWM speed control upgrade. I like the theory behind this modification but a few things are putting me off. Can anyone who has done it tell me if the maximum fan speed is the same using a PWM, or did the top speed end up slower? A question was asked about whether the PWM continues to draw current even when the knob is turned to zero. Is there any experience of this? I'm hoping to get one with a dial that clicks off but wanted clarification that this definitely stops any current draw. Don't want to have to remove the dash again because my battery keeps running flat!
Any knowledge and wisdom greatly appreciated.
