Heater Blower Motor
Heater Blower Motor
I am suffering with the heater blower motor on my K reg BX GTI. It has stopped working!! A sharp tap with a small hammer starts it up again but once it is switched off, the hammer is the only solution.
My local Citroen dealer is talking in excess of £100 for a new one.
Where can i try for a reconditioned one,or maybe 2nd hand with a guarantee.
Help please.

Its probably brushes but first make sure its getting a feed.
2 years ago mine packed up - been fairly good if a bit unconvincing at times - and I decided to sort it properly and see if I could discover full power.
The first thing I found was that I couldn't get anything to flow through the exposed connector - and after a considerable amount of cleaning I was about to cut the connectors off and make alternative arrangements when it started working and has been OK ever since. So check that this connector isn't the problem first. (Shake, twist, pull etc and see if anything happens.)
Its possible to get the motor apart with care, Others will tell you that the brushes are virtuall unobtainable new - so the answer is to buy something similar and cut it down to fit. (If its sintered copper - starter motor ones - if its carbon - washing machine )
The variable speed control is rather nice and uses a carbon track resistor on the back of the switch which in turn works through a pair of transistors (which I think are around or inside the motor system. Full speed is obtained by shorting out the transistors with a relay - but unfortunately most of the circuit boards on the back of the switch are wrong and it never operates. There are instructions somewhere on how to correct this problem and it involves cutting a link on the board and joining another. When I did it I had full fan power for the first time ever on the car.
So if its not the connector and you are certain the speed control is reliable and not intermittent - then its probably a motor problem - brushes or possibly the transistors or their fitting (dry joints). Your only source is going to be second hand - and I do not know of a source of reconditioned ones.

Thanks, i have checked all the connections & switches & everything seems O.K. so i am pretty sure it is "Kaputt". I will check again & get back to you to see what you turn up cavmad.
Thanks for your offer Sleepy, will keep it in mind.
Thanks for your comments jeremy will follow them thro,.

Before you scrap it, go to the club homepage, follow BXPRESS and rifle back through the "Last month" link until about September/ October last year. Full details on diagnoses and cures will be found there and I haven't scrapped one yet. For what its worth, I'll bet it is the copper straps within the housing.
