Post 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!

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.

Carefully remove the resistor

The fault is plain to see.

Refitment is a simple reversal of the above process.

This is quite handy as my heater has just packed up and only works on 3 and 4 not 1 or 2, do you have any handy parts numbers so i can go buy the right part? Also how much is a new one?

Excellent illustrations Major - Thank you.

As it happens, one by one the five speeds on my 1985 Montego Turbo's heater fan packed up this winter. Speed number 4 the last to do so. I know access means complete removal of the whole fascia which is about half an hours work. Having done that, as I'm handy with the soldering iron I now wonder is there a relatively easy resistor fix or do I wait for one to turn up in a local breakers and get that?

Any advice here appreciated.

Apparently ... in a parallel universe MGJohn drives .........A.......

Arrrrrggghhhhh......... ......

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


Not sure about any workarounds though, John.

Cool thread Major!

Everytime I see one of the resistor packs I think they look really primitive, with just the bendy metal on there to increase resistance. Now as you've probably gathered I know very little about electrics etc but surely something a bit more hi-tech can be thought up, maybe using proper resistors or something? Maybe a good mod?? Do the new rovers like the 45/75 use this style resistor pack?

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.

mine had the same problem, not working in positions 1 and 2. I went yesterday to a scrap and got one for 3, yes three poonds.

it was raining heavily... i thought about doing it in a sunny day..but i might be waiting for a long time , especially in Glasgow!!

I had to sort this problem on a mates 200 today, rather than buying a new resistor pack I decided to replace the resistors using standard ceramic resistors. I had already done this on my own car a while ago.
More details to follow, Dave I used some of your pics in the tutorial I made up.

Not really, there is no power at the resistor pack connector as long as the ignition is in the off position.
