Brilliant photographic tutorial. Just replaced the resistor on a year 2000 S40 using the above step by step guide. Many thanks!

I have the same Issue with My Fan: Either it comes on or it Doesn’t and when it does it come on at high speed for about ten Minuets and then Dies out: The Job Looks simple enough to Carry out except for the One screw concealed Under the Dash board? I have a Very Small Ratchet where one can Fit a Phillips Bit where one Can unscrew a Screw by Moving the Ratchet Handel up and down where the Screw Unscrews: Last week I Bought the Transistor of which cost just a little under 6 quid: Now in the still Photos: It showed on how to take the Unit out: But what it failed to do was to show on how to replace the Transistor: I think that it would be soldered on and would need a steady hand to Place a Soldering Iron or Gun directly onto the soldered Pins: as with everything there is an element of risk where the Soldering Iron could cause to much Heat, where the heat could Damage something: My Only hope is that I have a steady enough hand when I bring Myself to try and replace the Transistor

Fabulous article! My blower on the S40 stopped working. Changing the power transistor was very easy and solved the problem. One note: On my 2001 S40, the 10mm bolt was on the right hand side of the glove-compartment box, not the left as in the vehicle pictured above. Otherwise, it was identical. Loosening the bolt made removing the transistor very easy to do.
