Question about 2002 Mitsubishi Lancer

1 Answer

2002 Lancer heat/ac ductwork leaking water.

My Lancer is leaking water from the ductwork through the blower motor, and on to the passenger floor. It only leaks out when I make a sharp left turn, and only on the passenger side. It is not antifreeze/heatercore, and I have had the windshield checked for leaks. I believe it is condensation build up, but it seems like an awful lot of water for that, so I cannot be for sure. Any ideas as to what might be causing this? How to check it? And finally, how to stop it? Thanks, I've got the same problem, heavy water condensation under the glove box. I'll give it a shot.

Sounds like your drain tube for the A/C is clogged up. Get someone to blow it out for you, and you shouldn' t have this problem anymore.

SOURCE: 2002 Lancer heat/ac ductwork leaking water.

Hi,

I can't believe I found a site that talks about the exact problem I'm having with my '02 Lancer. It must be a common problem for anyone living in a humid climate. The hurricanes here in Texas produce this problem almost state-wide as all of our A/C units are flowing water like crazy right now.

I'd like to expand on the solution that briankc43 so graciously provided above. The drain tube for the condensate reservoir is, indeed, found on the firewall on the driver's side (left hand drive vehicles if there's another). It's a small (1-1/2") rubber tube bent 90 degrees pointing down. In order to get to this tube you will probably have to remove the air intake tube that houses the (I'm guessing here) MAF sensor in order to get your hand down to that area. Once you've cleared the way for your hand the tube pulls off easily from the reservoir drain port that pokes through the firewall. When I did this there must have been nearly 1/2 gallon of water that flowed out! If you have a small, narrow bottle brush it would work nicely raking what muck remains in the interior of the condensate reservior. At this time I do not know if there's any way to introduce more water into the reservoir in order to flush it but this should be sufficient. I guess you could rig a small tube and funnel or syringe to squirt water into the drain port. If this works it may not be such a bad idea to mix a very small amount of bleach into the flushing water to help kill off any fungus as it's a pretty darn good place to grow a fine crop of it!

Because the drain tube narrows by about 1/2 at its end it encourages stop-ups with the dirt and fungus that grows and is deposited in the reservior over time. I thought about leaving the drain hose off but if you did you'd leave yourself open to the possiblity of water getting back into the interior during wet conditions (water splashing up on the firewall) especially if the foam seal on the inside of the firewall was damaged or deteriorated.

I hope this helps those that have been monitoring this site.

2002 pontiac grand am se 2.2 4 cy blower motor has 5 speeds only works on 4 and 5 speed for heat and ac


The problem definetely sounds like the blower motor speed resistor. Under the dash on the passenger side you will see the blower motor it is round and approx 5-6 inches round the wiring from it will go to a small black plastic piece held in the duct work held on with one or two 7mm screws. They fail overtime from moisture in the ductwork, you should be visibly able to see it corroded around the computer chip. Approx $40 for the resistor and very common to fail. Let me know if this helps you

Its leaking under the dash on the passenger side when the ac is on, it feels like condensation from something under the dash but its alot and is soaking the floor of the front passenger floor


The water is probably coming from the air conditioner. Check the air-conditioning box or ductwork that surrounds the evaporator. There should be a drain hole in the bottom for the water to escape to the outside of the car. The drain hole may be plugged or the ductwork cracked or broken.

Also, this video can help as a reference guide...


Hope this help.

A/c condensation leaking inside passenger floor


Sounds like your drain is pluged. The drain is on pass. Side on fire wall. More than likely will have to get under car to find it. Try shooting some compressed air into drain port

Whining noise when AC or heat is on coming from engine compartmen


I suspect it is the blower fan and the ductwork for the air intake to the blower picks up the air in front of the engine compartment.

It would also be a good idea to have your alternator checked and use the A/C heat controls to see how much the blower motor is demanding from the alternator. Autozone and Oreillys will check the alternator on the car for free.

The air conditoner in 2002 Lancer does not blow out cold air. I've had the air checked and no leaks,and compresor is good. What could be the problem


If the compressor is working, and the system is properly charged, I would guess the accumulator is plugged, or the expansion valve is bad. I would need to know the high and low operating pressures to give a better guess.

Water leaks on passenger floor when air is on


AC drain hose stopped up somewhere, probably under the vehicle. Sorry I don't know where it comes out of the firewall or fender.

Blower control on heat/ac only works on highest level.


Your blower motor resistor, located under the passenger side dash down by the floor next to the blower motor, This will cause the motor to only work on high speed. Gm pt#89019101 around $60

A/c leaks back into front passenger side


Check the freon level in the A.C. unit, that's condensation, also you will want to replace the cabin air filter, and clean the drain plug at the bottom of the temperature control unit(big box where the evaporator, heater core, and blower motor are at).
