Single blower speed

Just changed both wiper boxes and worm on my late td5 (what a job!) put all back together, my heater blower now only has one speed. On its 'high' sped setting I get a dribble about the same as low speed, on low speed I get nothing . Took binnacle back out and swapped wires on terminals and I got nothing at all so changed back.

Any ideas? I can't think what could have changed

Resistor pack has thrown it's hand in or a terminal on it has become detached. If you go through life with your head in the sand....all people will see is an ar5e!!

Deffo not a terminal, I messed about with it whilst the dash binnacle was out.
When you say resistor pack, there is a resistor on the mechanism or do you mean the actual lever (used to call them rheostats when I were a lad) Disco 300TDi XS - Gone

Forgot yours is a TD5. The Puma has two seperate resistors 0.45 and 0.55 ohms which are switched in individually or in series dependant on fan speed selected.

Same principle, get a multimeter and check that your potentiometer hasn't an open circuit perhaps or more likely a short circuit as it is on high speed only? If you go through life with your head in the sand....all people will see is an ar5e!!

K9F. You out there listening?
If so how you keeping? We got snow today which is more defender weather than HD but I guess you'll still be over the moon with the HD. Out with the polishing rag each night and standing back in admiration?

Speed 1 on mine packed a while back. Speed 2 also now packed in and just speed 3 left.
I'm guessing both resistors are shot and we're running a direct circuit now?

Where are the resistors - I need to swap?

Forgot to add the illumination of the speed/numbers I also intermittent. The speed control isn't intermittent just the illumination.

not got round to fixing it yet but it would appear if I turn the a/c button on speed 2 also works ?

any thoughts

haven't tested it but the leads on the resistor pack had over heated.....
