very strange problems 1998 2.3
if I turn my headlights on, the right turn light on dash comes on and stays on, the right front head light and marker come on and turn light comes on without flashing. the left front head light and marker come on very dim and turn light dose not come on, the lelt rear light and turn light come on not flashing all this happens no matter what position the turn single switch is in.
If you turn the ac fan on high head lights off the right turn light on dash comes on and stays on, the both front head light and marker come on very dim and rear turn single light on not flashing. If you turn fan to low the turn light work as they should all but the dash as the right turn light blinks for both left and right single lights.
If you run just the fan you can run it half speed beford the above happens
If the headlights , fan and AC are off every thing works correct.

 

I feel sure you have a ground problem, likely with the left headlight, but I would also check the ground from the battery to the body. Ground problems usually turn on things that are not switched on, as the electricity tries to find a usable ground.

 

thank you
