Check heater pipes are hot ( two coolant pipes that go through the bulk head) if they are the heater radiator vents are closed, vent control problems, check under the dash, could be cables or they could be electrically operated. If cables, could have come off? If electrically operated check power to solenoids (fuses?)

My windows are not defrosting properly.

Do you have heat? Does the fan turn on? are you getting air from the defroster vents close to the windshield? If you have heat make sure the defrost control is working. I'd open the outside air vent and turn the blower on high speed. If there is no heat, the heater control valve is not working. Double check the radiator fluid tank, make sure you have enough fluid (antifreeze) Low fluid levels can reduce the hot water flow to the heater coil inside the car. If there
is no air flow through the defroster vents you may have a problem with the fan control, or the fan motor. Good luck.

My 99 chevrolet monte carlo z34 heat is not that hot and air works for defrost but not dash vents?

check radiator fluid level it take hot radiator fluid to pass through the heater core to produce the heat in your car VIA the fan. also check or replace your thermostat it could be bad and stuck in an open position thus radiator fluid not getting hot, no hot fluid no hot air
the other problem sounds like a duct hose under you dash has come loose locate and reattach.

I have a 99 dodge ram 1500 4x4 5.9. The check engine light came on and the temperature gauge is fluctuation up and down. I was told that I could be the thermostat or the sensors at the thermostat.

I am not sure if you have done this or not, but a store like autozone will tell you what the code the computer is throwing. I had this same issue happen last year, and come to find out, all my fluid pushed out of my radiator. I refilled the radiator, and cleaned the accumulation of bug that got between the radiator and the AC cooler, and have not had the issue since. Again though...the code will possibly help get you into the right area as to what the issue is if your fluid levels are good, and you have heat blowing from the vents. If there is no heat and good fluid levels, then it too is possible that the thermostat is bad.

Blower is only blowing vent air no heat, was working yesterday now is not.

radiator full? Thermistat stuck open. extremely cold and too much air flow on radiator.?Does it over heat at all? Back flush heater core and radiator and replace fluids, block off part of radiator in extreme cold areas. Check controls to be sure they are opening and closing correctly

Steam is coming in car through heating vents

this would be a bad heater core. this is located under the dash on right side inside the heater box next to the blower motor the steam is acctualy radiator fluid that runs through it.

1992 F350 Trans Blows Oil When Hot Any One Can Help ?

Check your fluid level. If a trany is over filled then the fluid will begin to foam and blow out of the vent once heated. Or you may have a overheating tranny. You can disconnect the tranny lines from the radiator and blow air through the fluid line ports on the radiator to make sure your not getting a plug. You can also purchase an external oil cooler to hook inline with the fluid ports on the radiator just make sure that when you install it to install it on the port that returns the fluid back to the tranny not the one that delivers the fluid to the radiator, in other words after the radiator not before.
