Volks,

I'm reassembling the dash on my 91 Vanagon GL after opening the
heater case and replacing the front heater core and blower motor, and
while I was at it, the foam rubber covering the various vent flaps.

The control cables are all in good shape but it seems like a good
time to lubricate them with some sort of penetrating oil.  However
there is no sign of any existing lubricant, so maybe it's not
necessary or even a bad idea (the wrong lube might rot the plastic
casing)?

To lube or not to lube?

TIA
