I replaced my heater core and when the dash was put back the fuel gauge, radio, climate control, interior lighting, and brake lights were not working.

Hello,

It sounds like maybe one or more of the fuses have blown. I've attached the fuse block locations and fuse identification below. The bottom under-hood fuse block contains a 60amp fuse, labeled IGN SW, for many of the systems you're describing that are not currently working.

These guides provide some helpful tips on checking fuses and wiring:

If there are any blown fuses, the next step is to find out why that happened.

Please let us know what you find, and we'll be happy to offer further assistance.

Thanks, Wendy W.
