Nissan Pathfinder electrical problem

I have a '98 Nissan Pathfinder which has developed an odd electrical problem. Whenever the parking lights or headlights are turned on the right turn signal indicator and exterior lamps come on, do not flash and stay on. Turn signals work normally with parking/headlights off. Just prior to this problem the brake light fuse blew. No further brake light problems after replacing the fuse. I can see from the basic schematics I have that the parking light circuit could apply power to the turn signal circuit. I have checked ALL exterior lamps and sockets. I would appreciate any help regarding components likely to fail or other troubelshooting tips. THANKS At first thought it sounds to me that it has to be a burnt or partially working light. So i would check all of them in all various postions. If you still cannot locate or they are all working then i would by a flasher for about $10. Let me know.Car Repair Talk's forum.
