Hi folks.As above,my heater fan is only working on 3,4,its either all or nothing! :'(Is it an easy job to do on the "F"?Ive been told its the resister and its possible to solder it.How easy is it to get at,and where is it? Would be much appreciated if someone could point me in the right direction,many thanks,Steve.  |

I also had this problem and replaced this part at the weekend. Really easy job.

Thanks folks.Where is the best place to get one from,and what sort of price should i pay?No MG/Rover garages where i live so a mail order part would be ideal.Unless someone has one spare lying around that they would like to sell.

Thanks again.Didnt realise there were so many centres about,especially in my area,five within a 20 mile radius,excellent.

Don't know if you read the thread I pointed to on my previous posting (above) but it tells you how to fix your existing resistor pack with far more robust resistors, and at a fraction of the price of a new one. I did mine and it cost me £1.20! That's replacing all the old coils, broken or not. Works perfectly and only take about 20 minutes (less if you're really good with a soldering iron).

Mine is also 3 + 4 only.  Thank you for this thread  Not looked at the car yet. Where is the resistor pack?  (Behind the glove box?) I can replace the resistors with Propper ones. |

I am a bit confused on the values of the resistors on the thread.
What will the difference be between the 1 Ohm and the 1.5 ohm?

I don't think it makes that much difference TBH. I used 1ohm ones. Also, I went for the ones that are wire-wound sealed in a ceramic block as they run cooler and are fire and water proof. All three are the same value (Replace the other coil while you're there). Click here for a link to the Maplin site. The pack can be slightly awkward to get to, but is quite easy to remove. Remove the glovebox for easier access, then the pack is screwed into the heater intake duct at the back of the heater unit. Detailed instructions, courtesy of Tony Thompson, can be found here. |

Thank you. The fan will move at different speeds depending on the resistance.  I already have 1 ohm and 1.5 ohm 11W from my wholesaler (£2 pack of 5). Will rebuild with the 2.1/1.5/1 Ohm as in his article. .  |

You're sort of right... However, the resistors are supposed to be the same value. That's because the switch connects them in series, so the slowest speed uses all three resistors, second slowest two, etc. If you put different values, it'll still work but the speeds will all be slower and not in even steps.

Rich. I'm going to play with this one, see how the fan speed difference affects the usage. Need the heat to the legs to be controlable. I have never had the 1+2 working . |
