There is a CEL, Check Engine Light, on the 1989 Thunderbird.
== ==
The check engine light comes on in a car when there is a problem with the engine. It will go off or be reset when the problem is fixed.
When the check engine light is on, the computer sets a fault code. Most auto parts stores will check this code for free and tell you how to fix it.
ONE thing that will do this is disconnect the battery , then reconnect the battery but if the check engine light comes back on then take the veh to the garage for more diagnosing of the systems
This car is 23 years old and it may very well be the check engine light bulb is blown and needs replacing.
Disconnect the negative battery cable for 5 minutes.
The engine coolant temp sensor can do that. If you have a check engine light on, have the codes read.
disconnect the battery for 5 to 10 minutes
its normal for the ck engine light to be on during this time as it is running it engine cks
