Help required

Ok members of this wonderful forum ….
I need help !!!

Blower only working on Max ( setting 4)

assume it’s the resistor ????? If I remember correctly

But where is it ?? how do you get to it ….
and can you still get them to fix it ??

 

[t-tony]

IIRC it is on the bulkhead near the blower motor.

Thanks for the video Tony …a lot more involved than I thought … but doable

 

[Althulas]

Easy job Malc if a bit of faff, plus you can clear any old rotting detritus, check the drain holes and apply a new bead of butyl to the back of the scuttle at the same time.

Bit confused….. RealOem shows this part

but it doesnt look like the correct part???
I also saw a video which showed one located inside the car above the footwell by the fan unit……
when you put this number in a search it doest look like t(e correct part…. Any one know what the correct part number is ….

can these be.repaired???

( by the way not got it out yet …doing it on thursday….)

 

[t-tony]

I've replaced a lot of those over the years (on various makes) Malc and as far as I'm aware they're throw away parts.

They're probably repairable, depending on just exactly what's gone wrong, but whether it's worth hunting for the right bits and d*cking around for hours is another question entirely. You may be better off striving for international rock-godness.

Or turning Korean and learning some dance routines.

 

[Mazza]

thinking about it …there should be a part number on it … so should be able to get the correct replacement

nothing to do with this thread but….. Started the 2.8 today …. wow it sounds really good

 

[Mazza]

Well got it all undone….

and the resistor pack should be below the fan and can be pulled up with a pair of pliers………no it aint ……

cant see how to remove the clip to under the blower……

any suggestions ?????

 

[Mazza]

and the blower cowling is in 3 parts rather with lugs rather than just one piece with two straps

You not finished that yet!

While you're in there make sure the drains a clear. Two of them. One either side of the heater air intake. Kind of like elephant trunks hanging down through the bulkhead into the engine bay. The bottom of the tube is flat to stop road muck being blown back up the tube. But because it's flat it traps muck and the area holds too much water that then overflows down the heater air intake into the cabin.

Well Guess what …. There are two resistors

according to RealOem…. If you have a Behr system. ( just std heater) Then the cowling is in three bits and the resistor is part number 64111375754


if you have air conditioning. ,the cowling is in one piece, and the resistor is part number 64116912633. And from the diagram this is the one that slots in under the blower and only accessable by removing the scuttle and wiper blades.

which leads me to believe that the one in my car is located in the car and requires the removal of some of the footwell trim.


So bit of a wasted morning looking in the wrong place ….………anyway ..Just put it all back together … and i did clean the drains out and I did replace the butyl strip on the scuttle.

I might have a look to see if I can find t(e resistor this afternoon….if it stays warm outside

Not wasted imo. A valuable learning experience and info passed on the wider group.
Thank you for your service!

This is something on my list of to dos also. Can any one confirm that the 4 pot cars have them under the dash instead? Seems strange to me that this would differ but the web seems to suggest the two locations. I've not looked yet plan to once I am home.

 

[Mazza]

Finally……. Sorted!!!!!

The resistor sits on the passenger side of the heater matrix in the cabin. (RHD car)

Just remove the glove box and the lower trim piece….and you can see it ( although it took me a while to spot it )

Its up where the yellow blue and green wires are…. Its stiff but will pull out….

a close up

After pulling it out disconnect the black plug… again was tight but just pulls off.

And the offending article….….

pretty rusty on all the terminals….although the coils were ok. (I took the metal cover off ..just 4 tangs to bend straight and it comes off)


But the reason it failed was a terminal has broken due to rust…. (The centre one)

I have ordered a new one and will be ready to collect from the Stealer tomorrow (£55.00…..), But online was more expensive!,!!!!

I will play with this old unit and see if it can be cleaned and repaired ….(just out of curiosity) , …..but if it works, it might be useful to someone at some point.

Drain clearing is my job this weekend, and so thanks @Duncodin as I now know exactly what I need to be looking for!!!!! Nice!

Lovely job Mazza, I share Ant's thoughts though, you are dragging this out a bit

 

[Mazza]

Just thought I would add this….

27 years on, and the part has smaller
(neater) coils and the tabs are copper so they won’t rust !!!!

shame they didn’t think of that when It was designed originally
