First, disconnect the battery as a safety precaution. One of these HID ballasts can cause electric shock or electrocution. Second, remove the front bumper cover. Then remove the headlight assembly for the ballast which needs replacement. The ballast can be found on the bottom of the headlight assembly. Replace the ballast and reinstall all removed parts. Reconnect the battery and confirm the repair.
Factory recommendation = 33 Front, 32 Rear
it's very EZ to change the fron and the back bank, just remove plastic covers and pull out one plug at a time and replace, use thread grease and torque. I did this on 1998 and there was plenty of room to work.

As in all electronics heat is the culprit..if a lamp is mounted (let us say at a ceiling in a warehouse the temperature at the ceiling area is always more than the ground level) and this becomes a cause for ballast failures. Voltage spikes and dips are also a reason for ballast failures. The ballast specifications should match with the lamp (undersizing it will also cause failures) eg. using a 32 watt ballst for a 40 watt lamp. Cheers. Chaterpilar
Not sure if the 2003 is the same, but on my 2001 I needed to replace Fuse 32, which is located in the fuse panel under the instrument panel on the driver's side
The exact results are not normally documented in manufacturer's literature, because they do not condone purposely mis-matching ballasts and lamps That being said, if both are RAPID-START there is a likelyhood that the lamp will light with this ballast. The light output may be less than normal and the ballast may have a premature failure. It's not going to explode. If you are deperate, help yourself, but I would always recommend a correct match...
