I would try to GENTLY use a wire coathangarz to unclog the drain from the top.

As for pulling the carpet out, you need to pull the center console, (upper and lower) and both front seats. 30-45 minutes maybe?

 

compressed air

 

That too.

You will also have to unbolt the bottom of the seatbelts.

 

Where is the sunroof drain located? I haven't looked at it yet, is it obvious?


1 - Open Sunroof
2 - Locate drain
3 - Feed wire through to unclog

Correct?

 

GENTLY feed wire.


The sunroof drains are near the front corner of the sunroof.

It would also be a good time to wipe any onther junk out of there too.

 

There are also drains in the rear, those are tough to get to, and are probably the ones that are clogged.

I believe the drains empty out just behind those little vents in the rear 1/4 panel, or somewhere right behind the rear wheels. The only real way to clean the rear drains is by dropping the headliner, and unhooking the hoses from the rear corners of the sunroof assy and blowing air or feeding wire through them

OR

Find where they empty out of, and blow air up throigh the drain...which is probably just as effective and definatly easier than dropping the headliner.

As far as the carpet goes, its not tought at all....just do what palmer said. I typically do this ASAP to every c900 that I get, and the foam is almost always wet when I remove it. That shit is just bad news IMHO!

 

Bah, the carpeting/foam is NOT coming out before SOC. My tools are locked up and I don't have access to them at the moment. And tomorrow my car will be in the exhaust shop getting muffled.

I'm guessing it's the rear drains that are plugged, since my buddies driveway is sloped kinda steep and I was parked with my nose up in the air. Rather than how it normally is parked, facing forward on a slight downhill slope.


I'm going to be in the cities Wednesday, and probably crashing at palmers house wednesday night. How long would it take to remove the headliner and carpet foam if we were all working on it? Could it be a quick 1-2hr jobbie?

 

Taking the headliner down is about a half hour. I used my shop air at 120 PSI and a long blow gun. clears them right out.

 

that much pressure could quite easily blow the drain hoses off the fittings at the sunroof. personally, i would tone down the pressure a bit.

in my '92, the rear sunroof drains end at the side vents, not attached to anything. just tucked in behind the stock grille work, hanging in the forward-most vent (there are 3 or 4 separate vents behind the cover/grille)

 

The fittings last time I looked are clamped....just what I did.
