I am working on my heater system on my 85 911. All blowers have been either replaced or refurbished. I checked the fuses in the engine compartment and recorded the following:
#1. 16 amp fuse- blown
#2. 25 amp fuse- blown
#3. 16 amp fuse- good.
The Owner's Manual does not identify location and calls for the following:
Rear window defogger, rear window wiper return (which I don't have) 25 amp
Heater fan 25 amp
Relay for heater fan 5 amp
My Porsche manual states the following:
#1. Heater blower relay 16
#2. Heater blower 25
#3. Defogger, rear window wiper 25.
Attached is a picture with the bad fuses removed and the positions are 1 on the bottom, 3 on top.
I assume the Owner's Manual is wrong and that I should follow the Porsche manual.
I'm wondering if there was a 16 amp fuse in position #3 because I don't have a rear wiper.
