Hooked up scope again between S1 (tapped into wire) and body ground. Confirmed 5V peak to peak (0-5V in fan settings 1-6) The square waveform is...
I 1st tried with fully charged NiMH AA cell (nominal 1.2V, but usually around 1.4V when fresh charged) DVM: 1.38V Scope: 1.42V Then a 9.6V NiMH...
Agreed on discrepancy between 5V measured vs. 11V in manual. Note I also used a DVM to check the voltages which ranged from 3.5V (LO) to 0.2V...
That confused me as well. I was expecting the reverse based on the manuals posted in this thread
OK, so I did this and the results are better. So I suspect that the BMC does need to be connected to the A/C ECU for correct output. This is...
It measures 6.4k ohm (plug removed, checked resistance on BMC unit between GND terminal (where white wire with black stripe on the plug side...
That is why I asked the question because I also saw that instruction on p.6. I could tap into the B+ line by cutting a bit of insulation so I can...

I found an oscilloscope and was able to determine that the waveform from the output of the harness that inputs to the blower controller (BMC) S1...
I'm not getting much V reading across pin S1 and GND. This is steady state result reading VDC: o=0.00 (fan=OFF) 1=.0.13 2=0.11 3=0.09 4=0.07...
I've located in my Prius the small grey box that is the blower motor controller (87165) CONTROL, BLOWER MOTOR. HEATING & AIR CONDITIONING -...
Great advice, will try. The only thing I would not be sure of is if the controller automatically stops voltage if motor is drawing too much...
Thanks. That is my tentative plan, but thought if I could better diagnose before installing the fan and find it was not it, I could return it...
The cabin air fan/blower suddenly stopped working in Dec. A 2004 with 119.6k miles. With search I am aware of the issues with motor going bad,...
I looked under 'Toyota, 2004, Prius, Heat & A/C, Cabin Air Filter' and the Fram one is not (or no longer) listed. Am I looking in the wrong...
<div class='quotetop'>QUOTE(htmlspinnr\";p=\"58153)</div> I live in the low desert, but on a recent trip to the Grand Canyon (thur Flag) the...
Opportunity for new product How about organically and hand grown corn for 'organic enthanol' Just being silly Al
I find it a defininte weak point - not the direct view behind me and the spoiler bar, but the view to the slight left and right behind me....
Nice to have a choice! I opted for any color to minimize the wait. When they called after 6mo. it was white model #7. When I asked about...
