I recently purchased a 2002 Impala that has a couple issues. The first being I can't change the settings to program a new FOB, I hold the "DISP" button on the radio until "settings" displays, but then it won't let me cycle through the settings or sometimes it'll just display and then disappear. The other problem is the interior lights are flashing. I tried replacing the fuses but they still proceed to flicker. I'm tired of trying to find solutions on google, so any help is appreciated. Thanks.
