RNS-D CD changer problems

[B@fink]

if theres a bit of damp about and it's had 3 weeks to do it it might have misted up the cd reader lens in the player part of the changer? The changer bolts in with 4 bolts (10 mm i think) so i'd be tempted to take it out and pop it some where warm and dryish indoors for a few hours then try it again to see if that makes it work, if it does, find the leak and sort it out, then dry the boot out, if not i'm sure a second hand one won't be too hard to find.
