2000 Jeep Wrangler electrical in HI?

I bought my 2000 Jeep Wrangler in CA and shipped to HI in 2006. I occasionally lose the turn signals, radio and wiper. Not in and out, but when I turn the car on they are on or off. I have checked the fuses. I figure it’s electrical, so want to seem like I know what I’m talking about when I take it to the shop. TIA

The trouble may be with the ignition switch since you say that the trouble conincides with turning it on.

When I put the key in and turn one click, I get all dashboard indicators and may or may not have radio/turn signals/wipers. When turn one more click to ON, I may or may not have radio/turn signals/wipers. Are the radio/turn signals/wipers connected in some way? Thanks
