Afternoon all! The interior fan motor is pretty intermittent these days, makes a horrible droning sound then turns off. You can hear the relay click on and then off, so assuming the bearings had it.

Replacement can be found, no problem. However, I have a cross country trip on Monday and would love to have some airflow and aircon working for it!

I can't see a way to take the assembly apart, but can definitely see a fair bit of metal around it so leans more towards the bearing failure. But, as a temp fix, would I be alright to chuck a load of GT85 or similar into it and hopefully free it up for a few days? Or will that make things worse....I use it on RC car motors and bearings that are on their way out and it works for a little while, but guessing this may be a completely different motor setup knowing Volkswagen!

Our mkii fan gave up similarly. I was able to extract it from the passenger footwell without too much issue (one connector a couple of screws and then fiddling) and did the same with some lubricant on the bearing. It freed up nicely and lasted a few more years until we traded it in for the Kodiaq.

I'd imagine you can do the same for yours.

Well, it smells of GT85, but it works better than it did!

Good stuff. The smell will wear off soon enough.
