Sorry absolutly no idea what this is refering too on this vehicle,i would assume its the fuel pressure ,a sensor on the fuel rail but although this vehicle is the same as our ford mondeo chassis wise the small petrol engines and mainly diesels that are bought here in europe will be different to the american cars,Its also the same chassis as a S type jaguar as well or so iam told

I assume you mean the owners manual. If yes then go to the Ford site to download it. for free HERE.

There is a heater blend motor that is directly behind the dash panel, center, bottom, by the floor. It has four 5/16" screws, and a 6-pin wire connection in the center. It takes about 5 minutes to change it out and the part is $42, give or take a few dollars for taxes.

The blend door is what switches the air to hot or cold

Make sure coolant level is full.

sorry to say u need a heater core and the system flushed

Hope this helps (remember to rate and comment this).

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.

When that happens it is usually because the coolant level membrane sensor is faulty.

Repair is not expensive, but must be done by a qualified mechanic.

Regards.

There are also two serpentine belt types for the 2002 sable. The S and U type engine. Take the old belt with you the the parts store. As for the diagram, I googled it under images and about a dozen correct ones came up. Remember the 2002 sable is the same as the 2002 Tarus.
