2002 Pontiac Grand Prix - multi-fuse related problems.The A/C keeps shorting out and the garage replaces the fuse. Where is the fuse box for the A/C located? Also, the radio display is dim/non existent - cannot see the stations/times but the radio/CD work. In addition the 'security' light on the dash is always on and the "change oil & service engine" light flashes intermittently off/on, even though I just had the oil changed. Any assistance would be great. Thanks.

I can't answer because I have other question open, sorry, but here I send any comments and clues to solve (I hope).

For the FUSE PANEL, location and description, I suggest check the 2000-Pontiac-Grand-Prix-Owners-Manual (page 330 and next). A/C have one "diode". Check it.

About your radio display, sound like a internal problem, keep in mind that the CD is working.

The Security Litgh, its possible that you have any problem with the THEFT system or any aftermark alarm (if you have).
