I thought these bearings were the dry running variety, and so if oiled make more noise and sieze :-/ ( won't poke my head out to far though)

Or more likely a previous dunking in water due to blocked scuttle drain was the root cause...

Could well be on both counts. I guess they're probably oillite bearings which means they're probably on borrowed time.  :-/

Dont think so TB.....ive never unblocked it....so it would still be blocked now....no water in scuttle drain....no damp/wet passenger side carpet.

The only thing i notice between old blower and 'new' one....as my Dad pointed out....the blades on the old one are a tad stiff......even tho it worked when shoving it accross a 12v batt....fully charged one that is.....i think the bearings have gone stiff.....therfore making it want a lot more current to start it than norm....and more current than speed controller can provide .

The scrappy fan blades move a lot more easier than the one i took out.

I spoke to my Dad earlier......he wants the old blower fan.......to disect it.....to find out why.....but i think he'll find the bearings are knacked in it  :-/

Tho i did PM Mark......to ask why the motors have a coil with a ferrite insert between both 0v and 12v inputs and the bushes.....dunno if this has anything to do with it  :-/

Also they have permanent magnets in them.......for the 'outer field'  I asked my Dad about those.....he was unsure why.....commented probably done for cheapness......

Maybe the coil/ferrite setup is needed because of the magnets.... :-/

My fan has stopped. It did try to power up on starting car a few times, but now nothing.

I checked the blue wire to brown wire feed wires, as from previous posting, nothing 0.1v.  Altering the fan speed 1 to 9 settings, gave no change in voltage. Brown feed wire to reg. is a good earth.

The voltage two wires to the motor is 12v both red & brown wires, so no controlled  earth from the speed regulator which is £128+vat p.n.90512510.  The fan seems free to move, goes to full speed when you bypass and add an earth to brown wire to motor.

I now think the electronic climate control ECC unit is faulty £600+vat?  I have remove PCB unit from back of  push buttons, can’t see any burning or dry solder joints. Control feeds from plug 8 & 18 ECC go to speed regulator & test OK. So do the red & brown plug 1 & 2 ECC measure 12v & earth.

I have had a problem for a number of years, with the car going cold after a hour drive and having to turn up the heat up a few degree, but not worth doing anything about it.

Has anyone replaced ECC unit or had one repaired.  The car is not worth spending £600 even though it is a 1995 Elite 2.5TD BMW engine.  My efforts at the breakers has not come up with anything yet.  Can anyone help put the old girl back on the road.
