i've been having issues with my 04 grand cherokee lately,, the issue is ,is that the engine light ( looks like a transmisstion ) comes on but doesn't flash, which is a good thing... but heres my problem, when i had my jeep in for serviceing and i had told the dealer about this, they scanned the computer and had came back and told me there was not issues with the computer... nothing happens to my jeep when this light comes on... what might be the problem ? im taking it back to the dealer again .. will the scanner tool pick up the problem weather or not the light is on or off ? im in the dam dark here on this one... ANYONE please help here... thank you folks
