Replace the thermostat in the engine coolant system - should be near the water pump or in the top hose to the rad. Mist in the heater vents usually means a corroded heater core, that should be replaced. Be sure to use the correct mix of anti-freeze, to keep the boiling point in the cooling system correct. Many who live in the warmer states, thing that plain water is OK, but it is NOT. Antifreeze contains corrosion inhibitors that protect the engine cooling system.

My 2001 jeep grand cherokee has a dark mist/smoke coming out of the vents, and defroster. But, the heater works fine. What could it be?

DO NOT USE STOP LEAK!!!!!! That stuff has no brain so you cant tell it to plug only specific leaks. It will go for the easiest hole to plug which can be a water port in the cooling jacket for the cyl heads. replace the heater core. Fix it right or bypass but please please please do not use anything that will stop a leak

I have a 1999 dodge ram with a 460. I have very little heat and there is a mist that comes out of the vents when i turn the heater on. I unhooked the heater hoses and ran water through the core and it ran...

The hoses might have a heater control valve on one ofthem,check and see,an you may have to replace it.Also make sure there is enough coolant in the system,it will not flow threw the heater core if there is not enough coolant in the system,the mist could be the hole in the heater core.

A/c is not cooling

If there's mist coming from the vents, it sounds like the heater core is leaking. Check the coolant level as well as the floor of the car for signs of dampness. You may also find the smell of coolant inside the car. If these signs are present, you should have the heater core replaced. Best of luck and post back with any other questions or concerns.
