heater problems

[faze30]

hey guys

I know the problem is listed in the wikipedia but somethings not right..

heater only blows on full.

so i changed the resister, and the switch. so the only thing left was the heater fan.

the thing that got me confused is. when he put the voltmeter on both the terminals on the heater fan plugs which connect to the fan. on level 1,2,3 was reading nothing. and level 4 it was reading. so it looks like no power is getting to the heater fan on 1,2,3

does any1 know what it could be??

you bought another dud heater resistor mate.

Already changed or not, the resistor pack is likely to be the problem, unless it's a one off, such as a wire to the switch crimped onto the insulation at the factory.

ive replaced the switch with a whole new heater facia.

the resister i bought from ebay. that probably why its shit.

but i just ordered a new one from bmw for £10+vat just now. i will have to test it when i get it this afternoon.

i will keep you all updated

Are you sure you got the correct resistor? I ordered a new one last week from Cotswolds BMW and it was £24 and that's with zone discount.

I have a Trade account with bmw main dealer as im in the trade so i get it a lil more cheaper

get a pic of the new resistor if you can

lol bmw sent me a totally different part. does any one here have the exact part number?

ive tried the realoem and bminispares but its not listed.

ive got bmw main dealer sending me 3 diff types of resisters to me tomorrow. but a part number would narrow it down for me as well as them

thats the resister which is on the front of the fan heater, i think which is on the early type e30s.

my heater resistor looks like this

64 11 1 375 754 found it. thereaoem has the wrong one listed

and bmwfans has the correct one listed.

[Rtaylor2208]

The one I got looks exactly the same: on the invoice the part number is listed as:

B64.11.1.375.754 and it was £22.85

[faze30]

64 11 6 912 633 (EARLY TYPE) not for my vehicle.
64 11 1 375 754 (LATER TYPE) This is the one i needed for my vehicle.

well hopefully it solves the problem when i receive it tomorrow,

i shall keep you all updated.

ok i have fitted the brand new resistor from bmw main dealer. And its still the same. only works on speed 4?

any ideas?

[daimlerman]

Usual cause of this is a lack of lubrication to the fan bearings.

There's an access hatch built into the bulkhead,then pop the spring clips that retain the housing,lift out the fan unit,clean and oil the bearings.

ive just oredered a brand new heater fan. if this doesnt work, i will burn my car. lol

[magpie]

how much is a new blower?
