seat belt winder problem

[R Power]

right guys, ive noticed a problem with my seat belt!!
when i pull the belt forward to fasten myself in, the seat belt takes its time to retract, so it is left loose for a about 5-10seconds rather than retracting instantly.
Now i have noticed one thing, this only happens after it has rained?? i find this weird, but im thinking is there a chance water could have leaked somewhere to have caused this??

Pull the belt out all the way and see if any section is wet. This'll test your rain theory.

Otherwise remove the pillar interior and go investigating

Edit: If you do remove the pillar interior could you go a bit further and check to see if magic button is connected to bass sub under the rear seats?

lol, no problem, ill have to check when the rain stops, as then there would be no point in checking if its wet haha. but is the winder connected to anything electrical by anychance?

Going by other cars, so not 100% sure.

I think everything electrical including the pre tensioners etc is at the latch box end.

Perhaps somebody can confirm though...
