Hello everyone, I need some help please, both the driver and passenger side seatbelts will not retract quickly enough or fully, which I believe is an MOT failure. I have washed and polished the belts and guides, but this has not helped. I removed the plastic trim to look at the reels, but they are behind the metal of the van itself. My questions are is it easy to remove and replace the reels and can you do anything to speed up the recoil if you do.
