First issue in a long, long time.

My Final Stage Resistor failed. Been laying low while my employer adjusts to the Virus with my car sitting in an semi air conditioned garage on a battery tender, went for a drive and no fan, no flow, nothing. Max AC, still nothing. I thought it was because the car was very cool from the garage and all of a sudden it was out in 85 degree weather, but still no AC.

Dealership is pretty slow so I pulled in and a few hours later I get a call. They tried some re programming, but that didn't do it. Part ordered and should be ready Thursday. Good news is new charge pipes and intakes really makes the car rip.

wow. have not heard of an FSR issue on more modern bimmers. They were mentioned every single day on the e38/e39 forums. something else to keep our eyes out for!

Agreed. Even more so when I was on e46Fanatics with my 330ci. I have a preferred BMW tech I always request and use, I'll grill him tomorrow when it's finished and post here with a full update.

Update.
Tech said the Final Stage Resistor failed. He said it was fairly rare and usually occurred on early 15' models (I'm a 4/16 build date) as well as some of the other F platforms. The procedure called for a software update raising the Evap temp limit, (usual cure to cure a freezing up system) and that failed. Next step was a new resistor along with a new blower motor. Covered under extended CPO, $900.00 saved. I did look up the resistor on FCP Euro that listed around $130.00 or so and I believe the blower motor was $350 I believe. Lastly, a FSR diy on a e46 was a real PITA but, the tech said everything on the F series is a fairly straight shot through the glove box only.
