How to Change Heater Resistor on Vw Polo (Model 9n) 2002

For this you'll need a torqe tool set. (Star Shape bit) You need the T20 size, but usually, they give you a little selection anyway.

It's pretty easy to do. Start by taking the screws out from undeneath the lower shelf, put the screws in the ashtray. Then take the rear centre console apart. (This just pulls off, it's only clipped in.) Behind the ashtray, pull the rubber mat away, this will reveal 2 screws. Take them out and put them in the ashtray. Move the rest of the centre console out the way. Theres another 2 screws on the left hand side. Take them out, this will allow you to pull the lower shelf away.

Once the shelf is out the way, theres a further 3 screws underneath where the shelf goes, remove these and put the screws inside the glovebox so you dont lose them. Then inside the top edge of the glove box, you'll see a further 2 screws and a lock catch. Remove all these screws and place in the glovebox so you dont lose them. The glove box should then just tilt out.
The video then describes the rest.

The refitting is just the reverse of the removal. Dead easy eh?
