Hi, I brought my 91' Coupe through a car wash a few weeks back. I was
horrorfied to find afterward that water had got into the car through
the moonroof and had collected around the overhead light(s) and a bit
had dripped onto the carpet. I have not noticed any leaking during
rains, so I assume it was due to the high pressure wash.

I want to fix this before it gets much worse, and also I am pretty anal
about my car and keep it up to the best of my ability. Is this a
common occurence with Volvos, and if so where does it commonly leak and
is this something a novice could fix or should I best leave it to a
glass shop? I want to still be able to use the moonroof so I dont want
to caulk it so the moonroof is permanently closed.


thanks,
CTV
 
Very often, what happens is that the drain(s) that channel water away when
the moonroof is open get clogged up. I use a straighten-out coat hanger or a
nice long piece of 18 gauge copper wire to push down the drain tubes to
clear them. Be careful though, sometimes the metal tubes connect to plastic
or rubber drain hoses that you could puncture or push off if you get too
agressive with your plunger wire. After that's done, get a turkey baster,
fill it with chlorine bleach and squirt some down the drain(s) to clear out
the fungus/moss. Then flush your baster with clean water 'cause chlorine is
not good for the rubber bulb!!

The usual cause on sun/moon roofs are clogged drain hoses, it's possible
to get water to leak even if the drains are fine if you blast too much
in there with a hose.
