87 GTA 305TPI: My dome light, map light (overhead console) power mirrors & glove box light will not work. Also, when I turn the car off, the radio erases all my stations. This just started happening, so I assume it's a fuse. Any suggestions as to which fuses those are would be greatly appreciated.

 

I'd suspect the Accessory fuse. It powers the items you mentioned with continuous +12 from the battery. If the memory for your radio is connected to this circuit, that would explain why it will not hold the stations programmed into it when it's turned "off".

In the future, if you suspect any fuse as being, just check each and every fuse for one that is bad.
