thanks for the info and response to my question and the helpful answers.

 

Good morning all, I have been reading through a slew of posts on the H3 blower issues/repairs and am still “seeking” a resolution for repairing ours…..
So far I have replaced everything, motor, resistor, h/S relay and control panel/module. Harness is NOT burnt or melted…. Not even scorched! And still no blower…. Harness ohm’d out fine. I am at my wits end (and tired of listening to “U know who” bitch about it

Does anyone know where the grounds are located and/or have a wiring diagram? At this point I am frustrated but have to believe I am just missing something small/stupid.

Any help would be greatly appreciated. Thank you

 

Step 1: STOP THROWING PARTS AT IT!
Step 2: KOEO rotate the fan speed control(center) clockwise.
Step 3: Open hood and locate the UHFB and remove cover.
Step 4: Pull #59 & inspect/swap/replace
Step 5: Pull #82 & inspect/swap/replace
Step 6: Swap #88/#87
Step 7: Swap #76/#75
While performing above steps with KOEO, observe any contact spark and listen for any blower motor humming sound.

Thank you for the great information, I have checked all the fuses but hey even the best of us overlook something small once and a while. Swapping the relays I haven’t tried.
For the record, I have full power (BAT V) at the control module, the mode
doors operate as commanded R/S switch and I can hear the blend door moving as I cycle the temp switch.
Fan speed switch was/is blinking and I even went through the reset/relearn process 3 x’s

Also, while my intent was not to keep reloading the Ole Parts Cannon, keep in mind I spent less time in diagnosis mode and all the while it was usually 10 deg F or less outside as I pecked away at the issue for most the Winter months
Not and excuse for poor problem solving but the reality nonetheless

Again I welcome the input and assistance

My '07 ONLY needed attention on the module( fix posted above) ALL SPEEDS WORK! I NEVER replaced any other HVAC systems components. ALL OEM!...Correction: {I replaced the radiator 10yrs ago}. To this day, I still get AC/HEAT VENT TEMPS 35°F-210°F---HVAC CONTROL + ALL OEM BLEND DOOR ACTUATORS ALSO WORKING PERFECTLY. After looking at many posts over the years, I own a Unicorn!

 

Ok Sports fans….sorry Fellow H3 enthusiast’s

So I got everything re-assembled and the for hell of it I checked for V at the blower connector(2-wire Brown is BAT voltage and the Orange is ground controlled by the resistor/relay)
nadda… nothing. Zilch
Soooooo.. I went to UHFB as hummerz had suggested and checked all fuses and swapped relays around… again big ole Zero
So now I start scratching my head and poking around. I have seen all the posts about burnt/overheated connections at resistor etc but was not experiencing that on my ‘06
Now for the big news…. What I did find was there is a white 6-wire connector where the blower/relay/resistor harness meet the harness from the BCM… was a tad difficult to get apart and as suspected 2 melted terminals….

 

Pull the 10397098 and post a picture.

 

I would but it looks just like your pic… just replaced it before I chased wiring…

 

OK, temp repair made and everything works again!

 

Here is a pic of the connector as found if you remove your glovebox. If you zoom in you’ll see the blower motor down and too the right… for reference
