Question about 1999 Mercury Sable
I have a 1997 mercury sable. The heater blows only cold air. I have the same problem. Ford repair shop replaced the heater core 2 years ago and it cost $900 to have done. The dashboard had to be removed in the process and we were told that this was not a do it yourself job. Could this be it again??? My car is a '99 model.
This happens ALL THE TIME!! Heater core is likely plugged with rust, yes. but a garden hose fix will NOT last. and the reserve probably IS cracked on bottom, as most are.They are relatively cheap from Ford, though. Have a REPUTABLE radiator shop do a Genuine Power Flush to the entire cooling system (not an automated fluid exchange many shops claim to be a "flush") and THEN have them unplug the heater in a similar fasion. Now is the time to replace the surge tank (old one is packed with rusty sediment that is usually partially plugging the cracks in it, and not very cost effective to clean anyway). On older, very rusty 2 valve 3.0 systems only other issues are the rear of timing cover gasket often leaks a little, and the water pump impellers can become eroded away (from rust) and water flow suffers. So... watch for residue or dripping from behind water pump. If minimal, a mild leak sealant added to a properly cleaned system with refill and tightening the bolts near leak will do the trick--otherwise timing cover gasket and pump replacement is needed.

The heater core sounds like it is plugged with rust, disconnect the hoses to it and use a garden hose to flush it out, in most case this will restore the flow.
