When I run defrost, there is a bad moldy smell. Only happens on defrost setting. Is there a filter to change somewhere?

2002 Chrysler Town and Country minivan. Stale, moldy smell on defrost setting. Happened last winter too. Is there a filter to change. It clears the window but I can't stand the smell. The heat on mid and floor vents don't give off this smell.

The condensation is not completely draining. You may want to see if it is plugged. Find the drain area in the engine compartment on the bottom of the firewall. Use an air compressor to blow air back through to clear it. I had a problem with that area which was a ford expedition design flaw. It was draining onto my O2 Sensor and damaging it. I had to make a bypass with a part form a GM truck.

Hi
i had the same problem, things to check for the smell
1. do have changed the oil or oil filter, if yes please check if there isnt any residue oil on the pipes which when get warm can easily come in through vent.
2. check the servo oil and its beholder is there any mild leakage, that can also cause it.
3. try to get engine wash if it is not done over years

In addition to a dirty cabin air filter (check your owner's manual for scheduled maintenance intervals on any filters), you may have a plugged drain in the AC evaporator and heater core region. During the summer, when you run the AC, moisture condenses out of the humid air onto the cold evaporator, just like it does on your glass of iced tea. The water drains onto the street through a hose or tube from the evaporator area. If the tube plugs up, or just drains poorly, fungus and mold will grow on the trapped water, and when you run your defroster carries the smell into the passenger cabin. Not sure why the defroster and not the heater emits smells, but generally that kind of problem comes from trapped water.

SOURCE: changing fuel filter on 2004 chrysler town and country

  1. Remove or disconnect the following:
    • Negative battery cable
  2. Raise the vehicle and support the fuel tank with a transmission jack.
    • Fuel line from the front of the tank
    • Ground strap
    • Inboard side of the fuel tank straps and front T strap fastener and lower the tank about 6 inches
    • Fuel lines from the fuel pump module
    • Fuel filter
  3. Installation is the reverse of removal. Tighten the fuel filter bolts to 40 inch lbs. (4.5 Nm), the main tank straps to 40 ft. lbs. (54 Nm) and the T strap to 250 inch lbs. (28 Nm).
  4. Start the engine and check for leaks.

Ok, i'm assuming your replacing them, there is an oval rubber stopper on the backside of the rotor, in the backing plate, located near the bottom. it will tighten or loosen the e-brake shoes inside the rotor, loosen them all the way off, then get a big hammer and give them a really good smack, be carefull not to damage the wheel studs, if your reusing them hit on the hat of the rotor, if replacing you can hit right on the rotor face.
Use some antiseize on the hub before installin your new rotors, and don't forget to readjust your
e-brake and reinstall the rubber plug

SOURCE: front vents will not work

If they are stuck on defrost,then the problem is a little vaccum line that comes through the firewall as all the climate controls are vaccum controlled,so look for a small green or black plastic line unhooked.

check the fuel filter connections first. If all ok, have a mechanic check it. If there is an evaporative leak, the check engine light should be on.

Moldy smell coming from Chrysler Town & Country doors


Try this...Mix a solution of 1/2 tap water, 1/2 isopropyl alcohol...about 1 quart - total should be sufficient. Put your window all the way down and where the glass drops BELOW the rubber moulding at the top of the door, take a kitchen funnel and push in-between the moulding/door panel and pour the solution into the door. Water should run out of the bottom of the door...IF it doesn't, one or all of the "ports" built into the bottom of the door are plugged...causing mold buildup in the door and creating your "smell" Locate these "ports" at the bottom of the edge of the door and clean them out with small STIFF wire. If the door drains water as it should - the alcohol will kill the mold in the door and the excess will run out...no harm will be done.
Good Luck

Filter to the defrost 2002 Intrepid


Sounds like you have a coolant leak in the heater, does your car smell sweet? If you do have a dirty filter it would only restrict the volume of air coming through the system

T&C heater controls


You don't need to replace the filter but you will probably want to go back there and check to see if you inadvertantly knocked a vacuum hose loose from the upper air damper.
