Blowin fuses

[Sodak]

Ok ..here's my problem. I keep blowin the 20 amp fuse for the lights..And it only does this when the lights are on.normal running around town durring the daytime hours and nothin happens ..turn the headlights on and 15-20 minuets latter you have a blown fuse.. the only thing that looks wierd is the passenger side blinker light on the dash will sometimes come on and stay solid then go out after awhile.changed all the bulbes in the tail light/side markers and front bumper(81) not sure if the problem is in the light swith/colume/or wiring? where might i start looking?

Wonder if the dimmer switch is shorting out, they can get pretty corroded inside.
