Ok open sunroof there are 2 drain holes use piano wire or something equeal take a low psi air tip nozzle and blow into drain then take a small cup of water and pour like an ounce of water into drain it should come out by lower door and fender area note mine was plugged down by fender hose was submerged in sand
I fixed the problem. First I had a mechanic blow the drains out with compressed air but there wasn't anything clogging them. He did notice the sunroof wasn't completely closed tight, even though it appeared to be from the inside. The closing mechanism caused the roof to move past where it needed to be instead of automatically stopping in the correct position, leaving a tiny gap that I couldn't see. Stand next to your driver's side door and look at the sunroof from the side. If it looks like it's completely flush with the surface, try moving it a bit until it's sitting at a very slight, almost undetectable, upwards angle. So far, it's been a couple of months and I haven't had any more leaks. Let me know if this works for you!

Water leaks are fun to trace out. the drain holes and tubes can be seen with roof open and can be unplugged with compressed air . but usually the headliner is soaked and leaks on to seats the windshield will leak on to passenger floor. remove glove box and check for wetness along "A" pillar.
open your skylight and feel in the front corners for muck stuck infront of the drainage holes. Use a pipe cleaner or other wire to poke through the holes and the water should drain out. It is a little difficult to see the holes but just feel around.
It may not be clogged. I believe the sunroof drains run down the roof pillars and then connect to another hose which exits through the body behind front fender. Unfortunately the hoses connect inside the car. Then again this might not be the source of your leak and water leaks are hard to address. Your dealer might be your best bet. If the sunroof drains are clogged, Honda knows entry and exit and they have to be unclogged with compressed air.
There are a total of four drains, two front, two rear. The front drains empty out inside of each front door jam. The rear drains empty out inside of the rear bumper. If you drain holes are clogged, use an air compressor to unclog not other as you may either break the drain tube or wack it out of place. I believe there is a technical service bulletin for Grand Prix sunroof mdels 1998-2005, In your sunroof leaks, contact your dealer for more info. Take care and hopes this works for you.
The a/c drain is likely clogged causing water to drain into the cabin. There is a hose coming out of the firewall under the car on the passenger side. You can try fishing a wire through the drain hose to unclog it. Sometimes it will have a few bends in it making it pretty difficult to snake the hose up. If you can't fish a wire through the hose you can try a quick shot of compressed air through it. Keep your face clear of the hose, if it is clogged you'll likely get a few gallons quickly out of the hose.
This is easily fixed if it is in fact a clogged drain. Open the sunroof, and you will see a small drain hole at each of the four corners of the opening. The holes drain down through the inner body work, and the water leaks out through a bottom weep hole. Try pouring a few ounces of water down one of the holes, it should flow freely, and you will see it puddle under the car. If the drain is clogged or flows slowly, you must unclog it by blowing compressed air down the hole, or use a long flexible wire to roto-root the clog. Do this for the other three drain holes, and you should be ready for the next rainfall or car wash. While you are at it, clean out the weep holes at the bottom of the rocker panels, there are several holes on each side of the car. Good Luck.
there are drain hoses on all all four corners of the sunroof. to access the front ones, remove the front inner fender liners. you'll probably see a plastic grommet/spout that the drain hose attaches to. in the rear, remove the trunk liners on the side. you should see the drain hoses running down the inside of the quarter panel.
The drain hoses get clogged behind the kick panels. Pull back the kick panel and reach in grab the hose and pull it out from the hole in the lower panel. Then I just cut off the end and watch the mud and water flow out then reinstall. There is also one in the rear wheel wells as well for the back drains.
There is no reason to remove the headliner unless its broke.
