 mine only works on high speed when powered directly so it sounds like it could be this ....regards chaz ------------- Current : 1995 BMW E34 540I Auto 98K Fully Loaded, Leather, Sat Nav & Dvd.

If it only works high speed, then I would check the relay. There is another instruction on Gale's page how to check that. Link is on my website below, look for Gale's page. ------------- E32 750iL,E36 M3 http://twrite.org/shogunnew/topmenu.html" rel="nofollow - 7 Series Tech Tips |

Nice one Shogun, Does the centre section of the pumper come off on all Models? Mine's a 93 525iSE and the last time I took the number plate off I'm sure it was one piece - could be wrong though. Nev |

I had the same problem with the low speed circuit on my 635. Resister was getting vey hot. Turned out there was a short in the wiring. Even when this was discovered & fixed the low speed circuit wouldn't work due to the fan motor burning out (worked ok on high speed though). Ended up getting a new fan/motor assembley for £123 which was pricey but could heve been much worse. ------------- AndyS Live each day as if it's your last - one day it will be. http://www.photostick.co.uk/view-933_BaurSig1.jpg" rel="nofollow">
