Why would the air conditioner work fine but the heater not work in a 1996-1999 Ford Taurus - Mercury Sable?

there are several things that it could be, the thermostat ($35), the heater core($150), or it could actually be the head gaskets ($110), or it can be a vacuum problem($30 Replace lines). the pricing is if you can do the work yourself, its parts only!

Another cause, especially with with ac working ok, is that the temperature blend door actuator / motor has failed.

This is a relatively common problem, and the repair is not too difficult. Autozone shows this part as only $15, and also provides an illustrated repair guide for the job.

the air conditioner and heater are two separate things.(not connected) ;) it may have a fuse. or the it could just be bad.

If "heater coil" is just another term for "Heater core", then yes, most all cars have them.See "Related Questions" below for tons of information about Taurus / Sable heater cores.

No one knows if:The heater is NOT blowing - or blowing on high speed only, or... The heater IS blowing, but the air is NOT hotEither way, the "Related Questions" below will get you started

no but it does have a manual hot /cold lever control box which is adjusted via vacume hoses attached to the heater control unit on the dash

The air conditioner or heater continually runs.

The heater switch is located in the middle of the car in the 1998 Ford Taurus. It is either above or below the radio.?æ

The Taurus does not have a heater control valve. Coolant flows through the core at all times. Be sure to review the "Related Question" below for much more about Taurus temperature controls

this is an indicator that the heater core has a small leak. there should be absolutly no anifreeze moisture in the car. your heater core is bad , sorry See "Related Links" for heater core replacement information for his generation of Taurus / Sables

Of course, set the heater/air conditioner temperature control to cold.

Most likely a bad heater core

The car has a new radiator and the air conditioner was serviced last year

You either have a bad a/c heater controller or a bad or weak a/c heater blend door..........

that's on the firewall under the hood, its for the heater/air conditioner.

The Mercury Tracer heater core can be found behind the passenger side kick plate. The heater core can be removed by disconnecting the water supply lines and removing the retaining bolts.
