Subject: <E36> Fan Blower Resistor
I have replaced the blower resistor pack in my 1992 325i.
Car was manufactured 9-91.
The resistor unit was found on the LEFT side of the plenum
a bit higher than the top of the gas pedal and a bit to the
rear. The ETM says this part is on the right side and shows
a sketch with comments including the phrase "with glove box removed."
Very misleading. Look on the left side. Just remove the kick
panel on the left side. The old part had a white base making it
easy to find against the black blower box.
Examination of the old part with an ohm meter showed
that a corroded rivet holding a thermal switch caused a high
resistance in the circuit. I tried compressing the rivet
(banged it with a hammer and drift) but the rivet showed
signs of decomposing so I bought a new resistor pack.
The new part cost about $46. It's better made
and real pretty with a BMW logo and part number and the
resistors are potted in a ceramic. Still kinda pricey though.
