What you have is a clogged drain. You are going to have and get on top of your rig, pull the over and clear the blockage. That is normal to happen over time. Had to do the same thing to mine. What is happening is the evaporator (the cool coil) gathers moisture an sheds it off, then is always some area for the water to drain out of the evaporator so it doesn't do what you are experiencing.

Mercedes Benz B Class 150 SE Fishy smell when you get into the car. However once engine running smell goes somewhat. Then when engine is turned off the smell comes back.

Could be some type of fluid leak, possibly coolant entering
the fan housing inside under the dash

Or a water leak from sun roof onto carpet

I have a water leak in the back of the Jeep Grand Cherokee 3.1 ltd 2000, wet carpet with water going in to the spare wheel compartment

Hi Wayne,

I checked for Technical Service Bulletins (TSBs) for your vehicle to see if there are any "known" problems with water leaks. The only bulletin I found was about the sunroof (if equipped) leaking into the passenger compartment.

Since there are no known problems for leaks in the rear, you will just have to do some diagnosis. Water leaks can be very evasive. They can originate in one place and accumulate water in another place. Here are some tips:

First, check the seals around your rear door and window. If there are any cuts or damage to the seals, this is most likely your problem.

You may need to remove the inner trim pieces from both the door and from the vehicle sides. Then run a hose over the top of the vehicle and over the rear door to see if you can see any water running on the inside. Be sure and look for water coming down from the roof area. Sometimes the mouldings and sealing material along the roof seams will leak. If this is the case, it will run down the inside wall and end up in the spare tire well. If you cannot find it this way, it may be necessary to remove the seats and ALL the inside trim so the headliner can be removed. I have seen roof leaks that are originating near the front that follow the roof reinforcement channel all the way to the rear. There are holes in the roof reinforcement chanel where you can look inside with a mirror and a flashlight (the headliner must be removed for this).

Another likely place for a leak is along the sides of the roof where the roof racks attach (if your Jeep is equipped with them).

If you find a leak in one of the seams, it is best to repair it with some (water-based) tub and tile caulk or (oil or water-based) plumber's dope. It is not recommended that you use silicone based RTV sealer because this contains acids that can cause the sheet metal to corrode and you will end-up with a worse problem in the long run.

I hope this helps you to get it figured out.

My dehumidifier is only a couple months old and is leaking water all over the floor while collecting in the bucket too. Why and how can I fix it? - I will take it back under warranty but would rather just...

The leaking problem usually happens for 2 reasons,

1. If your unit is equipped with a float valve inside the top of the water collection bucket, it's stuck in
the UP position. Turn the unit OFF and unplug for the wall outlet. Remove and empty the bucket
if necessary. Look at the foam ball on the end of the float valve arm. If it's in the UP position
jiggle it, so that it returns to the DOWN Position. That should stop the wter from overflowing the

2. If the bucket is not installed properly into the bucket holder. Remove the bucket, empty the
bucket, if necessary and reinstall it. Be sure that the bucket fits "squarely" into the bucket
holder from top to bottom and that it does not tilt downward at the bottom.

It's also a good idea to check the pump switch for continual draining, to make sure it hasn't been accidentally turned ON.

Hope this helped you troubleshoot and solve the problem. Please let me know. Thanks.

I have a 2005 Altima and there is a leak in the front passenger side under the carpet. Terrible mold smell. We've pulled the carpet back and the jute is soaked. Any idea where the water could be coming...

1) Check the pollen filter, its probably in a poor state if its not been changed yet.
2) Check the bulk head drains.
3) Check the sun roof drain pipes (usually run from under the sun roof, down the door pillars to the wheel arches, often covered by an plastic inner wing) clear out all the mud and debris.

Water leaks from the roof unit

This is condensate (which of course is water) that is coming from your unit. This is very normal ... Is it leaking inside or running across the roof and down the side of your unit? If it is going inside, there is a drain in your roof unit that is clogged. You must clear the clog. Remove the cover and inspect the base. Turn the unit off first.

I have a 2001 Chevy Blazer. While driving it and running the airconditioner I can smell coolant. I'm having to add coolant regularly, it's obviously leaking somewhere, but I don't see any on the ground or...

Maybe the coolant is leaking into a cylinder, slowly and also leaking out of the head gasket to the atmosphere when running under the increased load of the a/c.

If having to add coolant regularly, you're right, it must be leaking somewhere. It could be leaking out onto a hot part of the exhaust so look around there.

Headlights won't turn off

Trace which way the water went down ,,, a major plug around one of the front foot wells could be full of water ... also now you need to check all the fuses. Push on the carpets front and rear floor to see if it's not flooded out under the carpets. Some cars have computer modules under the front seats.

Marine ice maker problem

Mine has been doing this for years. You can check if the door gasket is good and sealing well. If not you can oder one and easily replace it yourself. Also, if I did not run my generator when I took a short ride ice inside would start to melt while the unit is off, usually around the case perimeter which would drip down to the bottom under the bucket and then when it was put back on it would refreeze under the bucket like a block and make it impossible to remove. I would sometimes just turn it off, put the ice in a ziplock in my frezzer to save it, let it defrost to get the bucket out and dry up the standing water.
