tony,
i think we are trying to re-educate the 'educated'
there is no 'fix' for this . what i have found over the years is a lot of bad information on forums that claim to fix things when they really do nothing.
general rule for a v35, if a door acts up have $1 k per door handy if you cant chnge the bits out yourself.
again there is not a quick fix for this problem..
