Why would the heat not be working on a 1997 saturn sl2

Does the fan work? and if so just blow cold air. This could mean the linkage that leads to the heatercore is broke/ disconected. try to manually open the valve ( to allow the heated coolant ) to flow through the core. It is probably along the firewall (back wall under hood behind engine) should be black water hose(s) going into the firewall valve is most likely there

I am looking for the location the heater core on the van

You didnt list the year make and model of the van but all heatercores are located inside the heater box. depending on the year and model there are some where the dash must be removed inorder to gain acess to replace the core, and some there are panels you can remove and then take heater box apart without removing the dash to gain acess to core. good day. heres a picture to help explain where the heatercore is .this would be inside the van on the pass/side under dash. good day.johnjohn2_154.gif

Hot water leaking under the drive's foot mat.what do we do? Also a lot of steam coming unto the front windshield/ screen from inside

The hot water is may be coolant and may be leaking from the heatercore and causing windows to fog, another thing to check is to make sure the heater box drain is clear and also the rear firewall drains, if you open the hood and look to the rear where the battery is thatarea fills with water due to plugged drains at the bottom, theres a drain on each side and one under the battery but the only way to get this water hot would be if the water would enter the heater box which i kinda doubt, this sounds more like coolant. i would have the hoses checked to make sure its not a hose going to heatercore and causing the leak inside, if it is the heatercore then this is an expensive job, i just noticed the year, a 1994, this may be a heatercore leaking. have the system leak tested and the leak location will be clear. hope this helps.

My heat is blowing cold air.

Could be a number of issues:
Low Engine Coolant
HVAC controls,
or Heatercore.

Check in this order:
Make sure your engine coolant is not low!

Does your engine heat up to the proper temperature? If not, change the thermostat.

To check heatercore try this:
Keep your air turned off, after the car's engine is heated up nicely, turn the heat on and see if you get some heat for a short while. If this happens, your heater core is plugged.

Hopefully one of these help fix the problem for you as diagnosing the controls is harder.

Heater only blows worm air not hot

Check these three possibilities: One, car has a bad thermostat. Two: Car has a bad heater control valve and three: Car has a vac leak under the dash that controls the heater Flap Valve. If this flapper isn't closed completely, cool outside air mixes with the warm inside (recirculating) air and cause a lukewarm air mixture at the vents.

First you have to remove the entire dash assy. Once the dash is out then you remove the heater/evaperator box. To remove the box you must first disconnect the heater hoses and the A/C lines from inside the engine compartment, along with a few bolts/screws that hold the box. There may be more bolts/screws holding the box to the firewall inside the car too.(can't remember, too many makes and models.)
