Question about 2003 Jeep Grand Cherokee
Car runs great but there is a light on the right side that looks like an orange engine
I see you lost your operators guide. in the glove box?>
it is an engine, and is called the CEL or mil (or ses)
the CEL is the CHECK engine light.
it glows , running, to tell you that the ENGINE brain, (PCM)
sees serious errors, or outright failures.
it also says in the missing opr. guide , to get car serviced.
on your car, we connect a universal OBD2 scan tool to the 16pin
dash port, and scan the PCM.
and see all those errors.
takes about 5min. work.
may auto stores, state side, do this for free.
or loan a full tool to do advanced testing, and analysis.

The information below was complied by me, it explains what causes the check engine light to come on and the process of finding the cause.
When the Check Engine light (or Service Engine Soon or small picture of an engine) is turned on, the systems computer control unit (called the PCM) has sensed a fault in the electronic controls of the engine and/or the emission system. When this happens you will seldom feel the car engine run any different. There are about 200 possible system faults (the gas cap is just one of them) that turn the Check Engine light on, to know what has developed a problem you must have the system tested, this is called an OBD2 fault code test, Kragen/Oriley and Autozone parts stores (USA only) do this testing for free.
