Had a wet boot for a while and now the red roof indicator light has come on permanently. Can't open the boot or the roof. In an emergency (wife's handbag was in the boot!) I used the manual method (arms still bruised from reaching through the ridiculously small gap behind headrests), mopped out boot and everything seemed fine for a few days. But now the light has come on again, can't open boot and the manual method no longer works (I turn the blue handles, pull them through, but then met with complete resistance no matter how hard I pull!). Is there some kind of reset procedure I should have followed the first time I opened the boot manually?
