It could be a couple of things, but check the easy things first. Check the anti freeze level with a anti freeze checker, if there us more water in the radiator than anti freeze the water will evaporate and the heater will blow cool. next check the thermostat, you have to take it out and heat it up in hot water and see if it opens up when it reaches the right temp when heated it will open up,those are usually the two most common problems.

How is the headlight switch removed in a 1994 Mercury Grand Marquis?
If it is the "pull out" type there should be a button on the switch accessible under the dash that will release the knob (Lights will turn on). Pull knob off and you will be able to remove the bezel which will allow switch to be removed. It is suggested that connector be replaced at the same time. Heat generated be switch destroys contacts. The question you ask is too involved for a proper answer. You may want to go to a car parts store, or book store, and get a repair manual for your car. They cost about $16.00 Or, go to a Public Library.

Why would a 2006 mercury grand marquis not blow heat?
There are many reasons. A bad Thermostat. A bad Heater Core. A Bad Control Module. Turn off the radio and IF you have the Climate Control Module, switch from AC to heat and listen carefully to see if you can hear the ducts moving inside the dash. If you can, then the Control Module is working and your down to the other two possibilities. Good Luck.
