I have recently replaced my power antenna mast and now cannot keep it
working. The motor works fine, but the mast only intermittantly goes
up and down. I suspect bad lubrication, but do not know what to use.
I didn't lube my mast when I put it in, and it's working fine.
What I did do, though, was crack open the motor case and clean it out.
It was full of plastic shavings, and I may well have lubed up a couple
of the rollers in there. I certainly operated the friction mechanism so
it'd move freely.
You don't need to take it very far apart, basically just take the lid
off and vacuum/blow the crap out.
Yes, good advice. I cleaned mine out and freed up the tension roller
that keeps the plastic pushed against the pulley. Water, salt, etc
runs down the mast and into the mechanism. I'ts very easy to remove
the whole antenna from the car, remove cover and clean/lube.
Yeah, basically you spin the nut off the antenna where it "attaches" to
the body on the outside, remove the bolts that hold it inside the trunk,
and drop it out. Then there are three or four bolts that hold the lid
on the motor unit (and you'll need to disconnect the power connector,
since it's not got a lot of slack).
