Leaking window took it back to the window man and he said that it was the drain that is blockedand not leaking window.

Is it a plastic rad?Sometimes you can get a crack in the plastic around the drain plug area.Add coolant pressure when warmed up and it leaks even with a new drain plug.

I actually took a 06 Commander in last week with the same problem. We checked the windshield carefully, and then drivers door moldings and then blew out the drains for the sun roof.
It still leaked down through the drivers' side drain line area of the sun roof, around the window moulding, and dripped right in the vicintiy of the rear of the radio.
We finally found the problem by dropping the head liner down and using an inspection mirror with a flash light. We disconnected the drain line and plugged the nipple opening and poured a small amount of water into the sun roof pan and located a hole in the drain pan just above where the nipple is formed for the drivers' side sun roof drain line.
We could not see the actual leak source without the mirror and flashlight, as it was on the interior side seam facing away from the drivers' door opening.

Since carefully sealing the drain pan seam just a 1/4 above the drain hose nipple on the interior side, slightly above where the drain hose connects, the problem appears to be solved.

It appears to be a manufacturing defect in the plastic seam in my opinion. Could just be a faulty radio if your car doesn't have a sunroof, or a leaking windshield gasket.

try fitting a flat rubber gasket on the plug before fitting. It is possible the there was one on it but it fell off unnoticed or was cracked and broke off.

Sounds like sunroof drains are plugged. They back up and leak into car. You need to clear with compressed air.

Most likely the sunroof drains are clogged. It happened to mine, the floormats and floors were soaked, especially behind the drivers side. Volvo wanted to charge me $550 to clear them out and dry out the floors. Instead I took it home, rolled down the windows, parked it in the sun and let it dry out. Then I found a mechanic who blew out the drains with compressed air for only $20. He had originally quoted me $50-100, but ended up doing it for less. He said the two back drains are clogged. You can try sticking a small flexible wire down the front two yourself, then pour water down to see if it drains properly out the bottom of the car. When I looked I didn't see the two back sunroof drains, but my mechanic said they were clogged with leaves, you might be able to clear these yourself too. I would have never guessed that it was the sunroof causing this, because you don't see the water leak around the sunroof, you only see the water backing up on the floor. Don't take it to the dealership, it's a simple job and they will rip you off.

You can try sticking a small flexible wire down the front two yourself, then pour water down to see if it drains properly out the bottom of the car. When I looked I didn't see the two back sunroof drains (they are smaller), but my mechanic said they were clogged with leaves, you might be able to clear these yourself too. I would have never guessed that it was the sunroof causing this, because you don't see the water leak around the sunroof, you only see the water backing up on the floor. It has to do with the way the sunroof drains drain down the side panels of your car. Don't take it to the dealership, it's a simple job and they will rip you off.

take the wiper off on the passenager side and remove the plastic under that and make sure the drain is not clog with anthing give these websites a try www.alldatadiy.com and www.autozone.com wish you the best of luck Michigan Man.

Yes.go for a ride with air con off then check if it gets wet again.if no, go for ride with air con on.if wet its the drain pipe thats blocked.

A cracked cover will not cause a leak. Overtightening the cover will cause a problem or perhaps they mishandled it and broke it and tried to put it back on. The seals around the camshafts may be at fault. When they replaced the fuel pump they should not have messed with this so I would have them explain what they did.

It may be due to the air conditioning hose being blocked. Therefore the water must be backing up into the vehicle, under the carpets and into the back seats instead of flowing out
