Hi all this weekend whilst attending Chatsworth the fan switch for the heater decided to stop working on hi speed. It still works on slow speed but for peace of mind i would like to fix it.

Do you know what the switch comes from? Ford/Rover?

Alternatively i seem to remember from another thread it could be possible to fix it. If so is this correct and how?

Cheers

TR7 and (I think) Austin Priceless used the same switches. There were two types though, one had 'ribs' along the ends of the levers, the other type was plain.

As said, they can be stripped for cleaning. The usual problem with the heater switch is that the heater motor draws more current on high speed than the switch can happily cope with, so either the plastic bits melt or the metal bits arc and burn out. A better fix is to rewire the high speed position so that it pulls in a relay which in turn feeds the high speed winding of the motor.

ETA: like this...

Its a TR7 switch, i know because i have had one and used a spare to replace faulty heater switch on my 350i. look on good old fleabay usually some cheap ones there.

Hi Jimbo..If its this one then you can have my old one as i have replaced all mine for new type to save the hassle of trying to find old ones, Its not in mint but it is 30 years old and still works and you are welcome to have it..Email me your address and i will try to get it off to you this morning..Cheers..Ziga

I always thought they had just the one speed - fast!!!! Maybe I should give mine a clean too!
