You have one of 4 problems, #1 the drain at the bottom of the plenum is clogged (this usually drains out under the car near the fire wall on passenger side if vehicle and is useful primarily during AC use to drain condensed water) #2 your heater core is leaking and requires replacement. #3, the outside air intake venting is not draining properly and allowing rain water and condensation to enter through the intake and into the plenum. #4 in rare cases coolant is leaking past the heater hose clamps at the heater core and allowing coolant to enter the plenum.

SOURCE: ac not cooling well - noticed 2 days ago steam coming out of ac vents.

That was probably not steam but escaping freon coming from the vents. Probably the best course of action would be to take it to an AC repair shop.

Smoke coming out of the vents in my 2001 dodge caravan only when accelerating


That to me sounds more like steam, as you accelerate the engine it causes more pressure in the cooling system. The heater core is essentially a small radiator linked in to the cooling system, that the warm engine water circulates through and creates the heat for the interior as a fan blows air across it.

I could be wrong on this, but to me it sounds like the heater core (Small radiator) has sprung a leak.

Antifreeze steam comeing through vents


Your heater core has a leak, it's like a small radiator that heats up and the blower motor blows air thru it to create heat in the car. It is leaking anti freeze into the heater box.

My 1990 subaru legacy was running fine-I went to the store less than a mile away and when I got home something was leaking from underneath the car and there was steam coming from under the hood..i don't...


Just because it was not hot to the touch, does not mean it is not a coolant loss problem----if the coolant is so low, there may not be enough to make the radiator hot (though usually the steam in the system will).
...a stuck thermostat can also let the engine overheat while the radiator remains cool (the fluid only circulates within the engine and is stopped from getting to the radiator.
...likewise a hose could have burst below and let the coolant out, over heating the engine, and the steam going out the ruptured/popped off hose; would look underneath..
...when cool, check the level in the radiator (likely empty),
...and less than a mile away, may not have ever heated the radiator, though usually only a mile to heat up the coolant
...of course there is always sabotage
...and water pump failure, (so no water circulated) causing overheating and no radiator heat, and possibly enough pressure to blow off a hose, but usually the radiator cap relief spring would allow pressure to escape (and that steam would heat up the radiator on the way---but if only steam in the radiator, it would cool off quickly after venting, because no more water in the radiator to hold the heat. all depending on climate,temp and further details , symptoms..
hope helps..

Steam coming out of vents and water runnind down inside of dash


Your heater core has corroded through. You need a new heater core. You may be able to get by temporarily, with bypassing the heater core hoses, located in the engine compartment. These hoses carry coolant heated from the engine, to the heater core. You remove the hoses from the core, and put a pipe in the middle, connecting the two hoses together using hose clamps.

Should there be a cool morning, or if you need the defroster, you won't have warm air. Just a temporary fix.

I am having trouble with my speedometer not working occasionally and now my seat belt light is coming on sometimes too. Is this the instrument panel cluster? Or something else? 1998 Dodge Neon. Backstory is as follows: -We take very good care of it and have one dedicated mechanic. -It has only had two owners; my parents and I. -We replaced the battery 2 months ago. -Mechanic checked to make sure the speedometer sensor was working. -We have had issues with the radio for years where it will randomly turn on and off, typically brought on by a stuffed trunk OR wet weather. -The speedometer works until we hit a bump and then the needle flies up and down or sometimes just stops working all together. -Mechanic has made mention of there being some Chrysler specific battery cable that is a smaller side cable and it is not in good condition. -Currently, my problem is that I can't find an old 1998 Dodge Neon in the salvage yard because yards are doing a lot of 2002 and newer vehicles and automatically crushing the others. The meat and potatoes of my question is what direction do I go in? And what of these symptoms ties to each other? And will adding new solder to the points on the panel fix it or is it something else? I'm trying to find least expensive to most expensive options and I'm rather handy but can't drop an engine or transmission or anything so keep this in mind. My handiness ends at resoldering the pins BUT I do have a mechanic I trust, but I fear that maybe I'm not combining symptoms properly. I have the money to repair an item I KNOW is wrong but not to chicken hunt around for problems.
