When i turn my headlights all the way on my dash lights and my tail lights go out.

SOURCE: headlights and dash light dont work

You would have to check and see if you are getting any power out of the light switch. There is a seperate wire for the headlights and the dash lights.

SOURCE: 2003 dodge durango #4 fuse keeps blowing,

OK there is a short in your car
take all the light bulbs out of the light that trigger the problem this break the current place one bulb in at a time checking that the fuse has not blown this will pin point where the problem is
once you find the problem you can replace the socket as it may have started to corrode check for water
once you replace the socket you should not have a problem
if you do let me know

SOURCE: '91 Subaru: dash & running lights won't turn on with headlights

This is a problewm I have been researching. On the 91 Loyale there are two headlight relays. The relay for the left headlight also controls the instrument lights and the running lights. If the right relay is working and the left is not, the left headlight will be dim because of a back electrical path through the high beam indicator light on the dash, but the instrument and running lights will be out. I have been trying to find out where Subaru put these relays, but three Subaru service departments have been no help. One dealer's service department told me to remove the large bezel around the instrument panel. I did and the relays weren't there. Lots of luck.

You have a short to ground somewhere in the drl-fog lamp circuit. Check for obvious wiring connector or wiring to drl & fog lamps. check wiring for pinched or broken wires coming from sockets. If you don't find problem, you can trace wiring from lamps to main harnesses and hopefully find source of short.
hope this helps.

When you turn on the headlight switch ,be it park lights or headlights, it sends power to the multi switch on the steering column. Check that out too.Mine was just dirty contacts, everything works now.
