leaking sun roof
New to the site and just purchased a 2005 Impala and as i washed it the other day i noticed water on the passenger seat. The day i test drove it it was raining and it didn't leak. Is there an adjustment that can be made or can you replace the rubber seal around the glass? Any help would be greatly appreciated. Doug.

Not to sound dumb but where are the drains and how do you get to them to clean them? And how do you clean them? Any help would be appreciated greatly. And thank you for the help. Would a repair manual be a good investment or a waste of money?

Should be in the corners of the roof hole. Open the sun roof pour water in the area around sun roof it should drain out quickly. You need an air hose to blow them out

Sunroof Drain Inspection and Cleaning
pour a bit of water into the catch area and see where it drains from and if you can access it from the bottom, do as MDTAHOE stated and try blowing it out...
You may want to place a towel in the sunroof area so you don't back blow water and debris all over your headliner and inside your vehicle...
Do regular wipe the drain area to prevent a muddy sludge from building up from fine dust that gets in when the roof is open...
Also understand that water getting up there is NORMAL, its easier to deal with draining the water away then trying to keep it out all together...

Sunroof Drain Inspection and Cleaning
Drain Hose Routing
A drain trough encircles the sunroof window panel and water is drained off by the drain hoses located at each corner of the housing. A drain channel spans across the sunroof module at the rear of the window panel and directs water into the trough.
Check to ensure the front drain hoses are routed down the windshield pillars and out the center of the pillar between the door hinges. Make sure the hoses are not kinked. Replace any torn or cracked hose. Refer to Sunroof Housing Front Drain Hose Replacement .
Check to ensure the rear drain hoses are routed through the rear pillars and out of the rocker panel. Make sure the rear hoses are properly routed in the metal roof slot and taped in place. Replace any torn or cracked hose. Refer to Sunroof Housing Rear Drain Hose Replacement .
Plugged Drain Hose
If a waterleak has occurred check for a plugged drain hose at each corner of drainage system.
Open the sunroof window.
To test for blockage, pour a small container of water into the module housing drain trough. Check each corner to confirm the drain hose is draining water.
Caution: Wear safety glasses in order to avoid eye damage.
Use compressed air, 241 kpi (35 psi) or less to blow out any drain hose that is plugged.
Test the system again.
If the hose remains plugged, check to see it is properly routed and does not have a kink. Refer to Drain Hose Routing.
Remove any hoses that remain plugged.
• For front hoses, Refer to Sunroof Housing Front Drain Hose Replacement
• For rear hoses, Refer to Sunroof Housing Rear Drain Hose Replacement
Remove the blockage using the following steps.
7.1. Push mechanics wire through the hose to remove the obstruction.
7.2. Use compressed air in order to blow out any remaining material.
7.3. Reinstall the hose. Refer to Drain Hose Routing.
Disconnected Drain Hose
Inspect the drainage system for disconnected drain hoses. Complete the following steps in order to obtain partial access to drain hoses and check for a disconnected hose.
Open the sunroof window panel.
Lower the headliner as needed. Refer to Headlining Trim Panel Replacement in Interior Trim.
Connect any disconnected hoses.
Ensure that the rear drain hoses are properly routed in the metal roof slot and taped in place.

Headliner Wet/Water Leak Around Sun Roof
There is also this bulletin..
#04-08-57-007B: Headliner Wet/Water Leak Around Sun Roof (Modify Drain Hose) - (Dec 6, 2005)
Subject: Headliner Wet Around Sun Roof (Modify Drain Hose)
Models: 2004-2005 Chevrolet Monte Carlo, Impala
2004-2005 Pontiac Grand Prix
--------------------------------------------------------------------------------
This bulletin is being revised to add leak repair verification steps. Please discard Corporate Bulletin Number 04-08-57-007A (Section 08 - Body and Accessories).
--------------------------------------------------------------------------------
Condition
Some customers may comment that the headliner is wet or that water is dripping out of the overhead reading lamp.
Cause
Both front corners of the sunroof have a drain hose running down the "A" pillar and end up down at the floor behind the lower kick pad on the left or right side. The end of the sun roof drain hoses may be laying flat against the foam at the base of the "A" pillar. This may cause a partially plugged drain hose. During a heavy rain, water that should be draining away may back up and overflow into the headliner at the front of the vehicle.
Correction
Remove the lower right hand and left hand lower kick pad.
After locating the hose, cut the end of the hose into a point.
Verify that the lower "A" pillar drains are open by pouring a cup of water in the bottom of the "A" pillar.
Check the drain hoses from the sunroof down to the bottom of the "A" pillar by using shop air.
Reinstall the kick pad.
