Code 650 is for a problem with the check engine light circuit.
It could be something in the computer, but chances are the bulb in the cluster is out. You may have to remove the cluster to replace the bulb.

Push in the door button. While pushing in the button, take a screwdriver and pry up on the door mechanism on the end of the door. Should unlock and allow the door to shut again.

The following are the general instructions on the start of diagnosing any electronically controlled engine or transmission problem.

The engine and the automatic transmission (transmission control is only for automatics, engine is still computer controlled no matter the transmission type) in this vehicle are computer controlled and in most cases when a fault occurs a fault code is stored in the memory of the computer control module. There are exceptions to this, such as the Mass Airflow Meter and fuel pressure problems. What must be done is to have all the basic testing done such as a scan of the system for fault codes as well as a check with a live data scanner tool for engine functions that are not within range of normal, a trained technician is required to know what is correct and what isn't, then based on careful diagnostics done from a factory repair manual the correct part is replaced or the wiring repaired or the computer replaced (known as the PCM or ECM,ECU), which is very rarely the problem. Other basic checks must be done as well such as mechanical problems with the engine as well as engine state of tune and mileage on the engine. The transmission can have mechanical issues as well such as no gear engagement at all or a failed pump or other pressure related problems. Also engine mechanical problems can and do cause many drive-ability related problem such as rough idle and other symptoms.

What kind of problems ?

1999 Chevrolet... | Answered on Feb 01, 2013


fuses usually turn black when they blow.
If not get a car bulb use a bare wire to make contact with the bulb and battery. touch the other contact to the battery to verify bulb is working.
connect bulb to fuse contact
touch battery with unused fuse contact.
then connect bulb to other battery terminal with wire.
bulb should light if fuse is ok

easy way trade position with another fuse of the same color

Either the wire or the bulb is at fault. The panel where the light is mounted needs to be accessed to test which.
