Cabin Blower stopped

I will report back. I may go silent for a week or more (waiting for parts and for time to work on it) but I will give an update. I'll take photos too.
As to the potential dealer costs - that is great summary for my wife

 

I ordered an AC ECU and BMC for $60 total with shipping on Jan-22 and the package arrived today.

Thinking I wanted to swap the AC amp first, I started to tear apart the lower console cover, got it off and found more parts in the way of the AC ECU with no obvious way to get that in the way stuff out of the way.

So I took the easy route and unplugged the old BMC and without installing the 'new' one plugged it in. Took less than a minute.

Cha-ching! It fixed the problem. (prize to Britprius )

I could even let the new one hang there deep under the dash and leave the old, but that would be sloppy. So I'll swap them proper later this evening, although reaching the mounting screws will take some contortions for my 6'3" frame. [Edit: Also finished the physical install. dropped a screw behind the carpet and had to pull that up, doh. Also the BMC needs to be properly installed as its heat sink is recessed into an open cut away in the A/C duct so it gets airflow to keep it coo.l]

Frankly if I'd known that the AC ECU and BMC were only $60 I'd have ordered them right away instead of trying to diagnose to perfect. Time is money too. But for some reason I thought they, at least the AC ECU were in the multi hundreds of dollars.

I''l be able to return the new blower motor I first bought minus $6.50 return shipment cost.

So total cost of repair $66.50 plus my time, about $35 more than it would have cost if I diagnosed correctly and didn't order unneeded parts. But still a lot less that dealer repair and I learned something.

Thanks again. Unfortunately I don't have the desire (or time) to go back and remeasure and find out where I may have gone wrong in diagnosis.
