hazard lights

[bluebronco69]

hey got a question, i have never been able to figure this out and i have been just working around it for along time but my hazards do not work. well they do work but i have to have the turn signal lever either in the left or right position and the key has to be in the on position (dunno bout the accessory position it is really difficult to ge tthe key to move to that side) anyways does anyone have any idea on this? i was going to check the flasher units for corrosion theya re new but maybe a bad connection at one of them? also since i have to have a turn signal on (either left or right) on the rear lights whichever side i have the lever is set to that light is slightly brighter than the other light, but the front ones are equal in brightness,
they do work with or without running lights
any one got any ideas?
thanks
