Hey guys, I just recently had the cabin blower motor quit on me. All other AC/heater components checked out, just the inside blower motor wouldn't turn on no matter what speed. I had a local shop that I've been using for years diagnose and replace a "transistor". Well, it just konked out again on my drive home. Same symptoms. What I would like to know is where is this 'transitor' located and does anyone have tips to troubleshoot? I suppose it's possible to have a failed replacement part, but I'm more concerned something else is causing it to fail. Either way, I'd like to pull it and at least check the unit to see if it's still good or not with a multimeter. From the photos I've managed to find, this looks like it might be located somewhere directly adjacent to the blower motor itself. I found this part on amazon that looks similar but I don't know the exact part number. I know sometimes 05 MDX and Pilot parts are compatible.
Saw a couple other threads from about 8 years ago. Pretty sure this isn't the compressor or the stator.

Thanks in advance!

 

Do you mean the resistor module for the blower motor? Don't those usually manifest as the blower either not working, or working at max speed only?
