dont touch any of them yellow wires with out un hooking the battery, safety first. anything yellow is airbag related.
and clock springs are not cheap, (250 new) so look further into your problem before taking on that task. they are not that hard to replace at all, but you will need to take the airbag off and the steering wheel and all the plastic around the column to get it off.
and being that they light up at night i dont think your clock spring is bad.
could be the radio, or the switches are messed up. maybe pick up another radio, and some new switches if cleaning them does not help. stock radios are always being sold here, as members like to upgrade their stereos. or ebay, they are not to expensive.
