It could be the door that should be shuting off the heater core area is not shuting.The door works with engine vaccuum.The vac. comes from the intake manifold. With your car being a few years old, the heat from the engine may have caused the vac. hose to dry out and crack or become disconnected. With the engine cold and off, look under the hood. A small size vaccuum hose should be connected to the intake manifold and run inside the cabin area. This is one thing you can check. I hope this helps you.

NEW AIR COMPRESSOR ON 2003 MERCURY SABLE AND ONLY BLOWS HOT AIR


Check that the wiring for the compressor clutch is connected. Have the system checked for the correct amount of gas as too little or too much will stop the clutch of the compressor. If the old compressor failed and the system didn't have a new receiver/dryer fitted there is every possibility that the tx valve is blocked. have the pressure in the system checked while running.as a blockage will switch off the clutch also.

My keyless remote for my mercury sable 2001 just stopped working. I changed the battery, but it won't work. Is there a fuse/connection ( less expensive ) that I could try ?


It will not make the car not heat unless you have an electronic climate control but it will make the blower that blows the heat not force the air into the car and you will only get air blowing when the car is moving. Check fuses first (refer to manual if your not sure where they are) and then make sure your blower (the fan) is working when you turn it on low/med/hi etc.

Hi,

Its your thermostat control which keeps switching between hot and cold.

It maybe the climate control unit.

Check these and get them tested.

Hope this helps

I have a 2002 Mercury Sable 3.0. I noticed when


The clicking noise is the motor for the "blend door". The heater core and the air conditioning side share the same ducting. When you move the knob a small motor moves the door letting the respective hot or cool flow happen.
The heater core is probably blocked. The engineers at Ford have the coolant hoses bypassing the core with a WYE at the firewall. The coolant takes the path of least resistance and stops FLUSHING the heater core and it eventually clogs.

2000 mercury grand marquis air conditioning won't work


1st Thing,
Located Someone With a Set Of A/C Gauges 134A Freon,
Make Sure Your A/C System Has Enought Freon In It, There Is a Low Freon Pressure Switch
In The Electrical System, Usually, 50-60 PSIG or Less On The Gauges, Will Indicate Low Freon, When Freon Is Low The Compressor Is Dis-engaged To Prevent Compressor Damage.
1] Low Freon
2] Bad Low Pressure switch
3] Blowen Fuse[s]
4] Electrical Problem[s]
[a] Digital Climate Controlled ?
Climate Control Self Diagnose From Button's On Unit, OEM Manual Explains This,
If Yor Auto Has Digital Climate Control.
5] Bad Compressor DC Coil

Note: Does The Compressor Engage, Click-On When Button Is Pressed, But Getting
Only Warm Air?
Is One Of The Compressor Aluminum Tube's Cold, Be Careful Other Is Really Warm/Hot,
If Cold and or Sweating, Dripping Water [Normal], You Are Blending Hot Air w/Cold
Air At The Heater Blend Box, Making Warm Air.
If This Is So, If A Vaccum Controlled Temp Unit, Check For A Vaccum Hose Bad,
Should Be Either 1or 2 Vaccum Lines Going Into Firewall To Feed The Controller
Unit, If OK, Might Be a Bad Blend Box Diaphram, [Control's A/C air, Blocks Off
heater Coil Hot Air].
If Your Auto Is Vaccum Controlled, Can You Changed From Bottom, Dash,
Defrost Air Flow?, Yes, No Vaccum Lost Feeding Controller, Still Might Have
Bad Diaphram Blending Hot Air w/Cold If Your Have Cold Alum-Tubing In
engine Compartment.
If Digital Climate Controlled, Might have Diaphram's, Vaccum Controlled or
electrical Servo's Controlled vs Diaphram [Vaccum] Controlled.
This Might Help, Hopefully, This Is Just For Starter's, There More To Some System's
and Without The OEM Mgr's Manual[s] You/Be Would Be Lost, especially w/Electrical.
Later, God Bless
