When you turn the lights on or on auo the high beam lights indicator on panel is on regardless of position of switch. High Beams work when you flip switch but when flip again to low beam, no lights at all, but high beam indicator stays on ... I have taken both bulbs out and tested bu connecting to battery and both beams of both bulbs work just fine.

Any help would be appreiated.

You need to check the fuses: ECU-IG 15amp located at J/B-1 ( junction box ) at left of steering column. and the other Dome 10amp at left side of engine compartment.

Find the Auto Light Control Sensor it has to go thru here from the combination switch to the lights.
