And there's no other live systems round there? I suppose it wouldn't matter anyway, apart from the ignition system everything else is low voltage right?

Hi Paul

My heater pack has failed and i'm going to follow your tutorial but i'm stuck already LOL.

Sorry....might not be too clear...

you will need a total of 3 resistors.....I gave four alternative part numbers..

so 3 of the first....Maplin H1R....OR 3 of Farnell 3270555 OR etc...etc.

you dont need one of each!

I have sent you a PM which might help.....

***The resistor values have been superceeded by ones closer to the manufacturers original values, please see posts further in this thread.***

Great British engineering.

Well done Mike (Cheers to Paul!)

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

My heater has just stopped working on 1 and 2. Didn't notice untill i started to get cold, will have to turn the music down. Thanks for the thread guys this seems a really easy mod to do. Will have a look in my scrap box, else it's a trip down to Maplins.

VW are just as bad. I bought a LHD Mk2 Golf when I moved to Spain. The owner had had this problem, bought resistors from the VW agent (v. expensive) only to find that the RHD resistor which he'd bought was different from his LHD one on the car.

He just left the new one in the glove box - so I desoldered the new resistors, fitted them to the old LHD resistor pack and "voila" - a free fix for me.

Then the fan motor died - bearings sheared - so rather than spend 100 on a USED LHD one, I fitted one from a Rover 200 mk2 which cost 10! So at least the car had one classy part on board.

It does seem incredibly low-tech for a modern car. Low-tech is fine if it works, but it obviously doesn't in this case. It looks like the cheapest solution done quickly rather than an 'engineered' solution. Frustrating.

Just my tuppence worth.

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

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

I would - this thread was invaluable for me when I fixed my dad's R45 that had this problem.

We just need a few more now, door alignment and taking door cards off would be ace

On the basis that the original resistors are gigantic, open, wire wound resistors that are designed to have lots of air freely moving across them, if I replace them with more conventional resistors as suggested above will this not cause a heat dissipation problem as the resistors will not have as much surface area but will still have a high amount of heat coming out of them???

Obviously there isn't much room for air to move very well, so I am concerned that I'll end up burning out more resistors (which could be why the original broke in the first place).... Not that it really matters at the cost of a couple of resistors every couple of years....

The resistor pack problem is also common to Nissans, Citruins and others.

I got one for a mkII 400 you can buy - a tenner inc postage if you're interested.
