Hi Malcolm, I to have a van I am pleased with, 1991 Abbey gts 214, mine also has one blind that covers the whole front 3 windows. Whay happens is the blind is so big, that the spring "goes", and when down will not retract correctly. My service man tried to repair it, but without a new spring it was hopeless. In your case it might be possible to tension the spring up. They are usually on the right hand side as you look out of the window. If you go for 3 seperate blinds, I would be grateful if you could let me know where you get them and how much. Best of luck with the problem
