It's getting colder, and it's time to turn up the heat!
I pulled up the levers, and spun the dial to 3, and got nothing.
Actually, I tried 0,1,2,3 and none of the dial settings worked.
Footwell blowers are dead.
I took off both the footwell covers and checked the 2 fuses.
They were intact, and I verified continuity with my MM, to be sure.
So, they fuses are not blown.
I opened the engine lid and put the key into ACC (key buzzing, but engine off)
I pulled up the levers, and spun the dial to 3.
Engine blower is silent. (Engine blower was new 2 years ago)
I believe the engine blower motor should turn on at this point
It would be very rare for both footwell blowers and the engine blower to all stop working simultaneously.
Next step would be the switch?
But, what are the odds that BOTH red lever switches die at the same time?
So, this makes me think it might be some kind of relay downstream from both red lever switches.
What's the next step? Check the engine compartment relay?
SOLVED
Summary:
* I verified the footwell blower fuses were intact.
* I checked fuse #8 in the frunk was intact
* I tested my blower relay in another 911, and it worked.
* I also verified the 3 fuses were intact.
* I verified pin #12 for that engine bay relay harness gets voltage.
* Then I found the culprit.
Blower motor was disconnected.
