Location of cooling fan fuse
The radiator cooling fan on your 1990 Ford Thunderbird Super-Coupe is supplied power via the BLACK, 18 Gauge, fusible link near the battery.If your cooling fan is not getting any power to operate (and you are certain that the fan motor is in good working order) the most likely cause of you fan not working is a failure in the Constant Control Relay Module (CCRM), which is mounted to the upper radiator support.I have replaced many of these because the circuit boards inside them like to burn.HERE IS HOW TO TEST IT:Check for power at the CCRM on pins 3 and 4 BLACK/ORANGE wires. If there is power there, the fusible link is good. If there is no power at these connectors, repair the fusible link or the circuit between the fusible link and the CCRM.Then, the Powertrain Control Module (PCM) turns the fan on by grounding the fan relays inside the CCRM at Pins 14 and 17. So if you have power on the BLACK ORANGE wires, You should be able to manually turn the fan on by grounding Pin 14 (TAN/ORANGE) for fan LOW speed and Pin 17 (GREEN/PURPLE) for fan HIGH speed. If grounding these wires does not get the power to come on at the fan motor, then the CCRM needs to be replaced. If this makes the power come on (at the motor connector) but the motor will not run, then you need to replace the fan motor. If grounding these wires makes the motor run, you have a problem with the engine coolant temperature sensor or the PCM.

How do you remove a 1990 ford thunderbird steering wheel?
There will be screws/bolts around the outside(under some kind of covers), holding the center section on. after you get that off there will be one nut right in the center(remove that and pull the steering wheel(most of the time you need a steering wheel puller)

Lack of power thunderbird sc 1990
This code doesn't cause any lack of power, the fact of the matter is that code 25 is most likely a symptom of the problem, the engine has excessive spark knock being sensed. Have the engine compression tested and have it checked for a misfire. Also have the fuel pressure tested, low fuel pressure can cause this lack of power as well/

Brakes to start car
The brakes are connected to your neutral safety switch. It may be a rod but more likely through the brake light switch. I would say that the b rake switch is bad and will have to be replaced. It will be under the dash behind the top of the brake pedal I suspect. It may also be in front of it. Hope this helps.

Left half of 1990 Ford
There are 6 back lighting bulbs behind those digital displays. As they burn out the displays get dimmer and dimmer till they go out completely.
You first need to disconnect your battery, then remove the plastic dash piece surrounding the instrument cluster and the 4 screws that hold the cluster in place. There is a "light bar", a plastic strip that contains all 6 lights that can be removed from the side of the unit. Replace with 6 new bulbs in and you should be good to go.
