This solution is for a 1999 Grand Am SE am/fm radio with tape cassette player:
Ido not know if this works for other Grand Am products past or prior 1999.
If the lcd display of the radio indicates "LOC" if you do not see anything on the display the small light behind the display is out and you need electronics to go further. If LOC appears here is what to do:
First put the ignition key to the ACC position.
2- press the HR clock adjust button once only ; the display should read 000
3-push the HR button successively until you reach 17 on the radio display
4-then press on the MN (minutes) button again until you reach the number 42
5-when the number 1742 appears on the display, press on the AM/FM button once and after on the POWER/VOL button to power up the radio.
