my transmission shift fine without turning on my headlight switch.But at night when i turn on my headlights on my transmission doesn"t shift and my radio lights comes on also when i step on the brake.does anybody no the problem.
We have a 1990 ls400, 160k miles, the power steering pump leaks fluid into the alternator causing it to go out. We're replacing both items but, the instrument panel light is going haywire while this is happening. Does anyone know or have had similar issues & did the replacement of the alternator & power steering pump fix the problem with the instrument panel? Thanks for the feed-back.
GREAT CAR, BUT HIGH COST TO OWN
