Default Anyone know C4 blower motor power requirements?

I couldn't find any info in either KATE and Bentley (which doesn't necessarily mean there's no info to be had). If necessary I'll pull one out of a junkyard and hook it to 12V w/ an ammeter, but hoping someone might know.

Less when they are new, more when the age?

Default Gee, thanks

The A8/S8 solar panels (which run the main blower for ventilation) are 30W, so I'm guessing ~20W. Guess I'm going to have to pull one and test it.

Default How big is the fuse? It is generally about 20ish percent below that.

What other motors do you think would fit in there? I have a Mk2 Volkswagen motor and cage sitting in my closet.

Default The solar panels probably run the blower at less than full tilt, no?

I would be very surprised if the fan on high drew only 20 or 30 watts... I would guess 4 or 5 times that.

Default VOLTAGE TIMES CURRENT = POWER

12v times 15 amps = 80 watts

Default What I'm investigating is the feasibility of using solar panel(s) to run the blower

like in the solar equipped A8/S8, so it wouldn't need to run it full blast- it just needs to change over the air in the car often enough to keep the interior temps down.

I like the black interior in my Europa Blue S6 a lot better than the original Ecru most of the time, but less so in July/August ;-)

Default True, but it shouldn't be pulling the fuse's limit, & the wire (2.5mm~10AWG) isn't rated for 80W

more like 55W depending on insulation, etc, and certainly not 180W (12X15=180)
