The blower runs flat out at times then will vary in speed down to a crawl. This also happens with the heater set to off.
I have been told it's the "spiders web resister" but where the devil is it?
Any help would be good.
the technical name if blower resistor packet.
is located inside the heater box underneat the dashboard.
to replace, open plastic cover on top of pedals, then look for a black square part that has some 3 to 4 wires going to it. this pice slides out.
unclip the wires, plug the new piece in and test it, it should work now.

[QUOTE]resistor packet is the name used on Bentley manual..[QUOTE]
That is actually really good to know because when I bought the part originally I also bought a Bentley hoping to figure out how to fix it....I could not find "final stage unit" anywhere in Bentley...
You are a welcomed addition to the boards...thanks!
On the sedan, convertible and coupe, the resistor packet is inside the car, as drescribed above.
on the e36 TI, they placed the resistor packet on the outside, next to the blower housing, you have to take the blower cover out and it should be on the drivers side. us spec..
if some ti owners wants pick of this let me know, i have the BMW TIS precdure pic.
Make sure you plug it well and that it sits back on its place well.
And since you be around the housing i do recommend the replacement of the AC/Heater microfilter. as it is a filter that is commonly forgotten of its replacement, clogging up and not only provideing less air input to the cabin, but also making the blower to work harder...
a new blower unit costs around 300
and if you get the unit on ebay, it will come with the plastic fan attached to the motor's axle. The problem with that is that on 6 cyl cars the replacement of the blower requires that the fins to be deattached from the motor, otherwise it will not clear the intake manifold to able to sit in its place, that is the blower housing underneat the fornt windshield. TIGHT job..
When you get a new parts, the fins will not come attached to the motor, so you can put the motor, then slide the new fins without doing the hard way. Also if doing this job, pay attention, there are two different colored fins, one for the driver, one for the passenger, make sure the new motor has the fins installed the same way..

Except that the final stage or resistor packet is accessible from the drivers side, and the microfilter from the passenger side beneath the glove compartment
Many thanks for your info.
I found the said unit on the passenger side of my car being a right hooker and after having my fingers broken and reset to enable me to exchange the unit all is fine again
By the way BMW in the UK call this unit a final stage resistor. 88 UK pounds sterling
