Technical heater fan speed switch question

ok, my setting one is dead, so i have gathered i need a new resistor pack, but no breakers seem to know what im on about, so can anyone measure the resistance of the resistors for me and ill put a high current resistor in (my uni has lots o this stuff that i can "borrow") id be eternally greatful!!! thanks.

EDIT: its a mk1 60 s-team (but readings from any mk1's will do)

If only fan setting 1 doesn't work but settings 2 and onwards do then that would indicate that the connectors to the resistor pack from the switch to the pack and possibly out the pack again for the circuit path followed could have become disconnected rather than dead resistors, I would try checking that first (y)
 
errrm, u have a mk2 by the sounds of it, mk1's only have 3 speeds. dont know if its the same on mk2, but if it is then yes itll probably be easier just to replace the whole lot.

EDIT: unless u mean 0,1,2,3 as in 4 setings but the biggest number is 3 and im bein dense :) then still yes probably easier to whip one out of a wrecked punto in the passngers footwell, look up attached to fan thing. just in my area there is no walk in scrapies with puntos, there all breakers that sell bits theyve taken off.

afternoon guys, i've got the same problem, mine doesn't work on 1 or 2, 3 works fine, but as we all know it shouldnt work on 0 as that is off

its the punto S60 that i have
 
Are these resistor values given in the wiring diagrams of the Haynes Manuals? I haven't got mine to hand to check.

However, if you remove the damaged resistor, should that not have markings on it to determine the resistance?

If they used standard type resistors it might but they are sometimes bedded into the plastic in a way that opening is difficult, don't recall the wiring diagrams giving any resistance values either (mines in the car atm)
 
Hi

I think this might be it, i've been on a Rover Forum for this,
For a 4 speed fan where the thre lower speeds have stopped it says use

1 x 1.5ohm
1x 0.47 or 0.56 ohm
1x .22 ohm

Thinking that the 1.5 will be for a very low speed i was thinking that using a 0.56 on speed 1 and a 0.22 for speed 2 might do the job.

Maybe you could split the differences to account for only 3 speeds, I'm not sure what values resistors come in but say 0.75 and a 1ohm might do it!

Progress......:idea:

LATER< Just read on an Ebay listing that 1ohm gives very low speeds

Might be compatable? I'll ask our sparky at work, might be middle of next week though.

ace mate, ill hold out for your sparkies answer aswell, thanks!!


I've been to Maplin today, I bought one .22ohm & one .56ohm,
At 80p each its worth a punt.
I live a long way from a Maplin so i took a chance!
I'll have to wait until i go back to work to try it [tuesday] but i'll let you know.
any speed lower than full will be nice though!
First job is to find which side of the resistor pack goes to which stage on the switch, I'll use my multi-meter to check this then the .56 ohm need to go to speed one. Get this wrong & the speeds will go MED -- SLOW--FAST !!

I'll keep you posted :)

UPDATE
I've got it all soldered together , just a case of getting to fit it now. I'm on 9.00-5.30 shift so it doesn't give me much chance this week. I might work by torch light if its not too cold tonight!
Saturday latest:)
