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.

Vw polo 2005 1.6 trend not getting hot air in the cabin always blowing cold air no mater how long i have been driving.

the way any motor vehicles interior heater works is by allowing water from the engines cooling system to circulate through a mush smaller radiator located behind the dashboard and the fan blows air through the radiator allowing the warm water to heat the air so when you select warm or cold via the interior controls a valve fitted in line of the water pipes that is linking the engine bay radiator to the interior one allows water to flow which makes me believe that valve is not functioning

Brake shuddering, interior lights stay on, white exhaust, signal light problems, heater fan will turn off periodically, smoke coming from back it worth fixing up? 1998 Ford Windstar GL Thanks!

The white exhaust is a bad head gasket
and coolant causing the white smoke

That's about as bad as it gets, forget
the other issues for now

I would part with it and stay away from
any van type vehicles,the transmissions
are terrible

I have a 1998 buick Regal and the heater does not work. When I am stopped the air from the vents blows cold but when I'm driving the heater starts to get warm again. This issue just started today (first...

I beleive that you may have low coolant because as your vehicle warms up the coolant volume increases which would give you just enough coolant to circulate to the heater core. When you are stopped your water pump also isn't circulating as fast and sending that little bit of coolant to your heater core, I imagine that if you top up your radiator or resevoir with coolant your problem should disappear. Keep an eye on it to see if it goes down again as this might just be air coming out of the system or it might indicate a leak either external (drip) or internal (whitish smoke in warm weather). Hope this helps.

When I turn off my ignition, my heater fan will keep running

I just started experiencing the same problem. Yes, typically after rainy days, I can never get the interior lights to go out after the ignition key has been removed. The car acts as if there is a door open. Now, my latest problem is with the heater fan. Of course, putting the control in the "off" position will turn it off but you can turn it on and off with no ignition key installed. I'm also having problems with my heater core too so it's been a pain in the but!!

I believe this problem has also caused my battery to die which is why I'm on this site in the first place!! I can't get into the car with the keys and the dead battery won't allow me to unlock the car!! When it rains it pours!!!

Smoke/Vapor coming from Air Vents

The whole dashboard of the vehicle will need to be disassembled, removal of stereo, temp controls, air vents, the dashboard will need to actually be pulled away from the front of the cabin, It is a very labor intensive repair.

Cold weater start problem. Oil smoke in from the heater vent.

The same problem happened to me and it turned out to be my heater core.

Normally smoke will come from the heater core when it needs to be replaced.

Also the smell is most likely anti-freeze and and you normally smell it when your
engine is running warm or hot.

Check your coolant levels to be sure. and the hoses leading to your Heater Core

heater cores for that vehicle normally run $180 - $230 and you need to remove your
entire Instrument Panel (IP) (Dashboard) to replace it.

I hope this helps!
