They simply took off the 12mm bracket bolts and SAWED around the inverter, cut the brake-lines going into the actuator and made room towards the firewall and frame. I can't figure out how they got it out? I mean there is a counterweight to stabilize the brake-actuator on the bottom of the bracket as well. nothing else is touched. its like they pulled it upwards & out somehow but there doesn't seem to be enough space but...

AI is suggesting that can you raise the side of the car at the weld, and that the whole side will raise just enough to take both wheels off. Seems unlikely - AI used to give its source, that’s getting harder to determine it seems.

I can turn on the a/c, that works. There are 4 air vents across the dashboard. I can only get air flow from the outside vents - the 2 by the doors. Middle 2, no air flow.

I pressed the button to switch to 'face" and "foot," no air flow from the feet either. Only from the same 2 outside dashboard vents.

All winter using the heat this was working. Hence the issue is new. Today I only put the heat on for a short time, but still no air...

I’m in Australia so my Prius is right wheel drive. The wider section of the rear backrest is on the drivers side so that’s the side i sleep on.

Of course it rattled like a spray paint can with a blown head gasket, as most Gen 3's purchased from FB Marketplace do.

Replaced the motor with a different one rebuilt by the esteemed Scotty Partin, a trained Toyota hybrid tech in Rockholds, KY.
