The water inlet valve may not be letting water in, the heater core and hoses may be plugged or the engine thermostat may be stuck open. These are the things to check under the hood. The mix door may be letting cold air inside to mix with hot air from the heater.

Have you changed the fuel filter? Possibly restricted. Check engine light on? Scan for codes that may pertain to this issue. Possible throttle position sensor or throttle actuator.

If you have emptied the cooling system and refilled it, you need to bleed air out of the system using the correct procedure for your engine. If you did not bleed air out after refilling, you will have air trapped in the cooling system and it will not function properly. You will most likely get an overheating condition.

The fuse panel is part of the gem. under dash, drivers side.

There is a fuse located at the rear of the radio unit! Remove unit to access.

you might want to have your local ford dealer have a look at this one , seems that ford had a recall on this problem a while back ( I don't know if its still valid) as they admitted that the fuse block connector on the firewall (just above the steering wheel shaft) has a defect in the gasket that seals out water from getting in there and corroding things up , I only remember this as about five years ago I had one come thru here for this same complaint and it was repaired under a recall warranty by ford

You may have a small leak in your water pump and it only leaks when you drive. Or god forbid a cracked block and the water is mixing with your oil (see white smoke coming from tailpipe?)

Here is a drawing and description of the location: he CKP sensor, located on the engine front cover near the crankshaft pulley, is used to determine crankshaft position and crankshaft rpm. The sensor is a magnetic reluctance type which senses the passing of teeth on a tone wheel because the teeth disrupt the magnetic field of the sensor. This disruption creates a voltage fluctuation, which is monitored by the PCM.

transmission failure is the most common issue with the 03 windstar. The average miles is 210,000 so if you are looking to purchase one suggest avoiding anything over 150k is this is a very costly repair around $2,500. My cousin had an 01 that she purchased in 2012, it was beautiful inside and out, unfortunately when the head gasket failed she couldnt find a repair shop in our area willing to do the work, you may want to make sure you have a shop in your area willing to work on the vehicle, No sense in buying something you cant get fixed if it breaks down.

Engine destroyed. Check over engine for any damage. My best guess would be something inside engine broke

Make sure the built in alarm isn't on by locking and unlocking the doors with the key remote

Replace the cable that is getting hot it is making a poor connection at the cable ends or the cable is corroded.

This is usually down to a high resistance in the +/-cables or bad connections on the battery. Also check the alternator connection and output.

dirty /corrosion at connection===short===alternator output high
