Low coolant level, theromostat is stuck open are 2 thoughts that come to mind.
Your model should just have coolant flowing directly into the core at all times. A simple check of the flow is to feel both heater hoses going into the firewall from a cold start. The hoses should warm up at about the same rate and get uncomfortably hot. This is a good indication that heat is getting into the passenger compartment.
If it appears that the core is getting hot, the next suspect is the blend door. This door diverts some or all of the air flow through the heater core and commonly fails on the Mountaineer/Explorer/Ranger/Mazda pickup...all of which use the same plenum box. The door is on a vertical axis and has a pervasive problem with the the plastic connection to the motor breaking. The door can swing back and forth randomly or wedge in a strange position, killing heat and AC efficiency. This is an expensive dealer repair, but there is an aftermarket repair kit from HeaterTreater that will address and solve the problem. Complete diagnostic information and diagrams are available.
This is a big job.. Get a manual on your car from DISCOUNTAUTOREPAIRMANUALS.COM .
you would have to see a mechanic about that problem
The thermostat setting on the water heater controls the temp.
Mercury Mountaineers have a "blend" door in the heater box. It is probably malfunctioning. You can find more info by searching for Ford + "blend door" or "no Heat"
vent door will be open to what ever setting u set it on regardless of what temperature setting you are using
Behind / below the glove compartment area inside a plastic case . You can see where the heater hoses connect to the heater core at the firewall in the engine compartment
Jump start car and do not run heater with engine not running.
Behind the glove compartment area inside a plastic case . From the engine compartment you can see where the two heater hoses connect to the heater core at the firewall
Probably because coolant level is low
110-120 degrees Fahrenheit.

Have you turned the control from Pilot to On? Have you increased the temperature setting?
When the heater resistor goes, your climate control fans will only work on the fourth setting. You can get a new resistor from any Ford Lincoln Mercury dealer, though they may have to order one.
In general it depends solely on the temp setting on your hot water heater.
Look at your temperature gage...If that is low, you might have a bad thermostat, which would keep your heater from working...I would check that first. also, check the cab air filter. i had the same problem. temp was fine but the filter was full.

How much will it cost me to replace the heater core in my 1999 Mercury
with your hands, jk but on my car you usally hold down the button that shows the outside temperature
location of heater control valve on 2005 mercury marguis ?
Thermostat setting may be same as room temperature ,therefore boiler will not ignite
"Pilot" is only when initially igniting your water heater. Some manufacturers state to leave it on "Pilot" for so many minutes before turning to on but this is only temporary. It should be then turned to "On" and then if you have a low, medium or high setting or degrees adjustment, adjust the temperature setting. Remember that most local plumbing codes and water heater manufacturers recommend a temperature of no more than 120 degrees F.
Because you don't have enough coolant in your radiator.
Assuming your temperature selector is not on "cold", the heater core is likely bad
No, the pump will continue to pump water and the heater will work from the thermostat setting keeping a constant temperature.
