94 lt1 z28 radio locks interior lights
 

Just had this happen to me while driving. My radio stopped working, stock. Then noticed my keyless entry won't work nor my trunk release from inside. Windows work fine. Interior lights don't work when door open or clicked on. I just replaced a drained battery from sitting for about two weeks w something possibly left on. I've been reading a lot everywhere and can't seem to grasp the problem. Rap is all I understand this year has but not sure exactly how to replace it. Anything to help would be great.

Keyless entry and hatch release button are powered from the same fuse. On a 95 that's #7 in the panel at the end of the dash. 94 should be similar, but I don't have access to my 94 manual right now. Have you checked for blown fuses?

Which radio do you have - standard or Bose? Standard radio gets battery power from #7 as well.

It's the Bose system, stock. I have checked fuses but plan to replace all them regardless.

Check Courtesy fuse #8 in the inside fuse panel. A blown fuse or missing power there would shut off the radio, the dome light, keyless entry, glove box lamp, hatch lamp, console compartment lamp, hatch release, and the map lights. I don't think that the RAP is involved.
