Before I go pulling things apart is there any common issue with these?

Here's a TMF link to wiring up a single speed fan to convert to
2 speed with a resister see the 6th post

Sorry check the last post in the link

will bring you here for a resistor.

I doubt a 10w resistor is sufficient, would need to be rated higher than that. I also think the link has changed as it now takes you to a selection of 10w resistors, not the 3.3ohm 25watt he quoted
Infact I'd be tempted to go even higher than 25w, I'd be happier with something closer to 100w so I know that the resistor will be capable of reducing the voltage without getting too hot under my dash! I can't remember what the heater pulls current wise, and what power rating really would be sufficient but the higher the better, within reason, imo

I converted my SPI heater to 2 speed which is the same casing as the MPI. Have a look at post Number 575 in my thread here -----> http://www.theminifo...rebuild/page-39

That looks amazing. Going to have to go through your entire thread. Kinda mad I saw the end before the beginning. It looks very well sorted indeed.
Was wondering what you plan on using for the blower motor switch?

Clamp maker,

Sorry missed this, thanks!
I'm using 2 toggle switches as like lots of other things I've done, the heater mechanisms modified as well

Did you also modify your SPi heater to look more like a Mki unit?

yep, modified the mechanism so it's up down rather than left right and made an aluminium panel to cover it all, which I had engraved today with off, screen and car.

Im now on the lookout for a similar resistor on this side of the pond. Very cool

Hi all,glad to find an on going topic on what I need to know. I have an 89 mini rose single speed fan, always found it a bit noisy so thought I would get around to this fan switch conversion eventually. I have recently bought a Rover P4 heater control which had on it a variable speed fan switch, or rheostat as it is known, check out Lucas rheostat on ebay. This was and still is used on P4s, series 1 Land rovers and other cars. It would be an easy fit on a mini and works well, the problem is it got very hot, to hot for me to fit permanently and feel safe. The switch is old so maybe this is the cause, any ideas before I spend my money?
