My son is a college student and we have traded vehicles for a few days. His 1994 Elite SA50 has electical problems- The headlights and tailights work fine but the directionals, speedometer and gas guage have not worked since he has had it (about a year). A mechanic suggested that at one time a mouse probably got in and chewed the wire. Any ideas on where to start looking for the mouse nest (and wire break)? Thanks
