Heater blower fan / motor

Suddenly stopped working tonight no matter what speed it was set at. then suddenly kicked in enough to demist windscreen enough to get me home. Now stopped again. Any ideas what it may be. Can't be a fuse so guessing motor or is there a resistor faul.

Update, just been out in dark, hammering with rain. Can now hear the motor temporarily run for a while then starts groaning until it stops. Anyone know how to drop the motor from behind the glovebox as will try the old WD40 trick.

Fairly straight forward.

 

remove the glovebox with 6 torx screws, then underneath you’ll see the motor, a few tiny screws hold it in, then it just twists to unlock and fall out.

 

chances are wd40 won’t do anything as it won’t be seizing, probably more like the brushes failing or the module inside

Cheers had a quick look and can see what you mean, few screws and looks like bottom of housing will twist out. Lots of people have used WD40 to fix as it looks common fult throughout VW group. Will also use a little white grease on it worth a try.

So finally, a break in the weather. motor was fairly easy to remove. Impellor a bit stiff so done the WD40 let's see if it does the job. However, if not a new motor it will be.

Oh well motor ordered complete with resistor. Worth a try.
