Good point Marc, thsnk you for your thorough explanations, and yes i do keep it on "Auto" but thought i should point out for othet UK members, on my UK (RHD) 2014 model, he blower motor and control unit is actually on the drivers side up underneath the pedals, not behind the glove box. Having removed the resistor and finding it to be only a year old, i proceeded to look at the manufacturing sticker on the motor itself, this confirmed a build date of May 2014, with the resistor removed you can then put your fingers easily through the space and spin the motor blades freely by hand, (with power plug disconnected of course ).mine felt a little tight, almost slightly stuck on the bearings as you pointed out, i squirted some WD40 penetrating fluid up onto the spindle, left it for about 10 mins, then spun it back and forth by hand, much easier to move now, so decided to plug it back in and connect the resistor ( you do not need to refit the resistor at this stage of testing, just plug it in ) ......turned on the power and Hey Presto ! fully working fan ..... It appears that the shaft and bearing was indeed a little dry with thevmoisture build up over a year or so, it is now running at all speeds and fires up immediately and as it should, will use for next day as is with all panels / shelf out etc just to make sure, but thanks to your invaluable replies and info we appear to be good to go ! ..... thanks again Marc, the forum is lucky to have someone who actually goes the extra mile to help, all the best to you.
