    I haven't taken any steps to solve the problem. When the A/C is running there is a noise with the fan on and the floor board on the passenger side fills with cold water.

    water leaks in on front floor, but it seems to happen more when it is raining. I cannot find a leak with a water hose running over the windshield.

First, make sure the condensate drain is clear. Now here is the kicker. I had the same problem till I took it to a GM place. Make sure there is a rubber elbow attached to the drain pan so that the water can drain down instead of being blown back from the wind. Ever since the mechanic attached that elbow, I have had no problem.

That is a VERY easy radiator.
Loosen radiator drain plug and drain coolant from radiator.

2003 Mitsubishi Lancer started to leak water on passenger side under dash.


I am guessing that this occurs after you hae been running the Air conditioner and is COLD water. I ran into the same problem and found that the drain line from the Air conditioner pan was clogged.

If I remember correctly, the drain line comes through the Firewall on the drivers side. I was able to push a small piece of tubing back through the line and loosen the clog. A bunch of junk came out and I have driven last summer and so far this year with no more problems,.

Water collection in the air conditioner. Drain is


You need to clean the drain out as your first step. This is accessed by raising the vehicle on a lift then using something like a coat hanger pressed into the drain hole at the base of the firewall next to the transmission bellhousing on the passenger half of the vehicle.

The heater has a musty smell,I suspect i need to


It sounds to me if you are having a "musty smell" then you might have a problem with your condensation drain line for you a/c system or a small leak on your heater core. If it is plugged then water will collect in the vent system causing a musty smell from the water not draining and if there is a small leak on the heater core then coolant can collect in the vent system. I would run the a/c on a warm day and look for water draining from the vehicle around where the dash is located to check the drain line. As far as your air cabin filter most are located behind the glove box. You usually need to remove the glove box to get to the filter.
