It's your blend door actuator, big job for a $6.00 part, the dash has to be removed to access unless your mechanic is a magician.
my heat doesnt work in my2000 lincoln ls what causes this
no and you suck
Moisture evaporates, thereby cooling off body heat
Sounds like your thermostat could be stuck open.
If it`s a heat pump, they do that, heat is not instantaneous with them. If it`s a furnace the fan/limit switch or fan delay timer whichever you have, needs to be adjusted.
the make and model of the car would help in determining your problem it is possible that this could be a problem with a switch that controls the position of a door that blends heat with cool air.aka-blend door actuator.
If it won't cool it's probably out (low) on coolant (freon), And it probably has an overheat safety switch.
No.
IF THIS IS NOT A HEAT PUMP SYSTEM... COULD BE; thermostat connecting(calling for) heat and cool together. connnection problem in wires- or bad thermostat. find wiring diagram for t-stat, read up on checking voltage in thermostat in the heat-or cool mode. they are separate. does t-stat have separate 'heat-cool' mode. in other words- do you have to switch to heat mode-or cool mode. if it is a heat pump--ask again with that stated in question.
either your temperature contol switch is faulty or the heater thermostat is faulty you can also check the blend air door switch it might not be switching from heat to cold air http://wiki.answers.com/Q/My_1995_town_car_air_conditioner_is_blowing_hot_air_but_is_full_of_freon_and_the_compressor_is_engaging_any_suggestions
Heat travels from warm to cool.
It does cool faster, it has a lower specific heat capacity and so cools at a faster rate, only by a few degrees over say 30 minutes, but it is.
