Rover 200/400 - My heater Fan doesn't work on speeds 1,2 & 3 - "How Do I?"

We get this question pop up many times.
Here's a short article on "How to" replace the heater fan resistor pack on a 1995> Rover 400

Remove the glovebox. Two 8mm bolts secure it at the lower hinged edge. Remove the bolts, press the catch and out comes the glovebox. Magic!

 

[Dr Dave]

Here's the culprit.

Release the connector, it's quite tight.

Move the cable aside, to allow access to the securing screws.

Undo the two screws, a stubby cross-head screwdriver is best for this, as the dash moulding gets in the way.

 

[Dr Dave]

Carefully remove the resistor

The fault is plain to see.

Refitment is a simple reversal of the above process.

 

[Dr Dave]

I remember replacing those resistors years ago! Split the heater box itself to replace it!


Not sure about any workarounds though, John.

 

[Dr Dave]

Also, would resoldering the 'springs' fix a blown one?

Yes, probably but the solder would melt fairly quickly as the coil heats up. Thought about doing it on this one, but thought better of it.

 

[Dr Dave]

No problem Paul, good stuff!

 

[Dr Dave]

Great British engineering.
Shanghai Automotive must be dying to get their hands on this.. :lol:

--Alan

Ah, this type of failure happens to many cars, not just MGR, Alan..

 

[Dr Dave]

Yay!!!!! All my heater settings work now!!

Thanks Paul!! :rocker: A well worthwhile 'mod'!

My handiwork ain't too pretty, but it works!!!

cheers
Mike

Well done Mike (Cheers to Paul!)

That's what we refer to as a "Result"

 

[Dr Dave]

Yeah, know what you mean Alan. This arrangement works but not for much more than 6 to 8 years....

 

[Dr Dave]

This would be a perfect topic for the "How Do I" section .

Great idea....shall I move it?

 

[Dr Dave]

Went back to work!


Moved....

 

[Dr Dave]

If anyone has trouble getting these resistors I can supply the lot for £1.80 including P&P.
There are four resistors in total, two resistors are needed to achieve the 0.22 ohm value.

I might well take you up on that offer Paul if you still have some handy.
I have a couple of packs here that need repairing.

 

[Dr Dave]

Here - on a 400/ZS - your's is basically the same

 

[Dr Dave]

Just three - enough to do one repair and see how it goes! :spanner:

 

[Dr Dave]

Just enough resistors to do one repair!

 

[Dr Dave]

Flippin 'eck!! that was a quick response!! Thanks very much. Just found website tonight looks like it may prove very useful!! Thanks.

No problem, pleased to have helped!

 

[Dr Dave]

can you send me a set plz technozen, it seems a common problem
and thanks for your posts

I didn't know Paul was a charity!? :err:

 

[Dr Dave]

Ah....do I see a Technozen's ebay shop coming up soon?

 

[Dr Dave]

I know somebody else with the exact same fault - it appears to have lost it's earth....

Switchpack is probably my next port of call.

 

[Dr Dave]

Great to hear of your successful repair!
