I'd personally let it sit broken -- unless you're talking about the AC blower fan (which blows air conditioned air out of the dash vents (only)
3) red levers (between seats) both open the flapper valves to let heat into heating system AND activate the trunk and footwell blowers. As originally delivered, 911s heat was delivered/controlled solely by the flapper valves, with little hot air coming through until the car started moving. Sounds like, notwithstanding the fans being inoperable, you're witnessing proper operation of this passive system when you pull up the levers (but that pushing down the levers isn't causing one of the flapper valves to completely close.
4) the switch (knob) between the seats controls how fast the footwell blowers spin -- the footwell blowers should only work when the red levers between the seats are pulled up and should turn off when these levers are pushed down -- you control where the footwell blowers send the heated air with the bottom lever on the dashboard control -- all the way to the right sends heated air to the defroster vents, all the way to the left sends heated air to the heater vents below the dash -- center sends heat to both -- you'll know if the footwell blowers are working, as they make some real noise (especially in the high setting) |
HA! you are probably right about the fresh blower lol. But, you know, I'd like for everything to work. So maybe I'll work on it at some other time. Maybe I'll dig into it, and just see if something came loose.
Ok, the HVAC lever does change the direction of air, foot or windshield.
The levers between the seats then probably make the engine motor work (is there a way to check that?). So my footwell motors are not working then. Or perhaps the knob is not working? I do not see any change in operation when I turn the knob. I do not hear any fans engaging when I twist it. I have replaced the fuses that are in line with the footwell motors. What else can I check? how do I check if it's the knob or the motors?
When I turn on AC, it blows air, as it should... except its not cold air. I have no idea if there are any leaks in the system, since I haven't tried filling it up (well I did, but it was via one of those cheap bottles... which didn't work).
