'STOP-ENGINE TEMPERATURE' warning light flickers & chime sounds

your best bet , take it to a qualified repair shop. Have it checked for DTC'S - diagnostic trouble code's

Audible Warnings Description and Operation
The audible warnings alert the driver of a system concern or a critical vehicle condition. The instrument panel cluster (IPC) generates audible warnings through an internal acoustic speaker. The IPC receives audible warning requests via the serial data circuit. If the IPC receives multiple audible warning requests, the warning with the highest priority sounds first. The following lists the audible warning priority and the pulse rate:
Fast rate chime (200 pulses per minute)
Medium rate chime (150 pulses per minute)
Slow rate chime (50 pulses per minute)
Single chime
Door Ajar Warning
The IPC activates the door ajar audible warning as requested by the body control module (BCM). The BCM sends a serial data message to the IPC indicating the chime frequency and duration. The door ajar warning sounds and the appropriate DOOR AJAR indicator illuminates in the driver information center (DIC) when the following occurs:
• The body control module (BCM) determines that a door, driver door, passenger door. The IPC receives a serial data message from the BCM indicating the door ajar status.
• The vehicle is not in park. The IPC receives a serial data message from the BCM indicating the gear position.
• The vehicle speed is greater than 8.05 km/h (5 MPH). The IPC uses the vehicle speed information from the ECM to calculate the vehicle speed.
Fasten Safety Belt Warning
The IPC activates the fasten safety belt audible warning as requested by the BCM. The BCM sends a serial data message to the IPC indicating the chime frequency and duration. The fasten safety belt warning sounds and the fasten safety belt indicator illuminates when the following occurs:
• The ignition switch transitions to ON.
• The inflatable restraint sensing and diagnostic module (SDM) detects that the driver's seat belt is not buckled. The IPC receives a serial data message from the SDM indicating the drivers seat belt status.
If the seat belt is buckled when the ignition is turned ON, the chime will not sound. If the seat belt is buckled while the chime is sounding, the chime will stop. If the seat belt is unbuckled after the initial transition to ON, the chime will not sound.
Key-In-Ignition Warning
The IPC activates the key-in-ignition audible warning as requested by the BCM. The BCM sends a serial data message to the IPC indicating the chime frequency and duration. The key-in-ignition warning sounds when the following occurs:
• The ignition switch is OFF.
• The body control module (BCM) determines that the driver's door is open. The IPC receives a serial data message from the BCM indicating the door ajar status.
• The BCM determines that the key-in-ignition switch is closed and the signal circuit is low. The IPC receives a serial data message from the BCM indicating the key-in-ignition status.
Lights On Warning
The IPC activates the lights on warning as requested by the body control module (BCM). The BCM sends a serial data message to the IPC indicating the chime frequency and duration. The lights on warning sounds when the following occurs:
• The ignition is OFF.
• The BCM determines that the drivers door is open and the signal circuit is low.
• The BCM determines that the headlamp switch is in the park or head position.
Park Brake Warning
The IPC activates the park brake audible warning as requested by the BCM. The BCM sends a serial data message to the IPC indicating the chime frequency and duration.
• The body control module (BCM) determines that the park brake is applied.
• The vehicle is not in park. The IPC receives a serial data message from the engine control module (ECM) indicating the gear position.
• The vehicle speed is greater than 8.05 km/h (5 mph). The IPC uses the vehicle speed signal information from the engine control module (ECM) in order to calculate the vehicle speed.
Additional Warnings
The following warnings have an associated instrument panel cluster (IPC) indicator or driver information center (DIC) message:
• Check Oil Level
The IPC activates the audible warning as requested by the BCM. The BCM sends a serial data message to the chime producer indicating the chime frequency and duration.
• Low Fuel
The IPC activates the audible warning as requested by the BCM. The BCM sends a serial data message to the chime producer indicating the chime frequency and duration.
• Oil Pressure Low Stop Engine
The IPC activates the audible warning as requested by the BCM. The BCM sends a serial data message to the chime producer indicating the chime frequency and duration.
• Reduced Engine Power
The IPC activates the audible warning as requested by the BCM. The BCM sends a serial data message to the chime producer indicating the chime frequency and duration.
• Trans Hot Idle Engine
The IPC activates the audible warning as requested by the BCM. The BCM sends a serial data message to the chime producer indicating the chime frequency and duration.
• Turn Signal On
The IPC activates the audible warning as requested by the BCM. The BCM sends a serial data message to the chime producer indicating the chime frequency and duration

This is the simplest & easiest fix, to make your '94 Cont. drivable, without having to listen to incessant CHIMES beeping every five minutes, due to faulty sensors and electrical glitches from the junk message system. Go under the dash, on the right side of the steering column and remove the plug (10 wires) from the 'warning chime module.' There is a tan/yellow wire in that plug on pin #7--that is the "tone generator" wire. CUT IT.!!! Now, when all of those faulty inputs try to get to the warning chime module--they CAN'T! Problem solved--no more beeping. This does not disrupt the chime from sounding if you open the door with your keys in the ignition, or with the lights still on--it continues to protects you from THAT. Remember to watch your OWN coolant & oil levels--to make sure no REAL problems exist--and you're good to go!

A service manual will provide a series of tests that may help troubleshooting steps. But, since this sounds intermittent then it may be a connection problem. Try a visual inspection looking for loose connections.

scan it yet?
one input is wrong,finding it might be easy or hard.
easy the scan tool told you
why fear such a tool?>

if no DTC set we can check all inputs to the silly chime box.

Check the warning sensor adjustment as the eb system may be worn enough to set it off if the adjustment is too close.

Generally the temp light means the engine is too hot assuming its the light for the engine.
Check the fluid level in the radiator and the overflow tank, and see if the radiator fan runs when the engine warms up.
Could be a problem with the thermostat too if the engine is running hot.

this problem is caused by a tiny micro switch that is attached to the door latch inside the doors, the stick and give this false warning, have replaced dozens of them, it is called the "door ajar" switch oddly enough :)

depending on what door it is check the switch in the a post of the b post if its back doors. also known as the light switch, remove switch and clean the switch switch cleaner or well known brand wforty, or leave switch on remove the rubber seal and spray in the switch as you push it in do this a few times and flick the switch a few times.

temperature sender unit top of engine cylinder head make sure its okay
and make sure wire going to it is not grounding
if it grounds or earths it will send the gauge up and down

Section 13-09: Gauges, Warning Devices — Chime System 1996 Windstar Workshop Manual
DESCRIPTION AND OPERATION Warning Chime Systems Three distinct sounds are used to indicate the area of concern. Seat belt warning generates 1 chime per second
key-in-ignition generates 2 chimes per second
headlight on generates 4 chimes per second.
Key-In-Ignition Warning The key-in-ignition warning will sound when the driver's front door (20125) is opened with the key in the ignition switch. It will continue to sound until the key is removed, the front door is closed, the ignition switch is turned to START or the vehicle speed is over 24 kmh (15 mph).

Safety Belt Warning When the ignition switch is turned to RUN or START from OFF or ACC, the chime will sound for six seconds or until the safety belt is buckled.

• The safety belt warning indicator lamp (10C859) will activate for 60 seconds or until the driver's safety belt is fastened. Both the chime and lamp activate at the same time.

Anytime the ignition switch is released from START and returns to RUN while the safety belt lamp or chime is activated, the safety belt warning lamp or chime will remain activated until either the timing sequence has been executed, or the safety belt is buckled.

Headlamp Switch On Warning The chime will be activated if the headlamps or parking lamps are ON, the key is not in the ignition and the driver's door is opened. The chime will sound at a rate of four per second.
