Speedometer Problem

Recommended Posts

I HAVE A 1993 LEXUS SC400 AND ALL MY GUAGES WORK FINE . ALL BUT THE SPEEDOMETER IT READ 20 TO 40 MILES IN-CORRECT. THE TRANSMISSION SHIFTS FINE. IF'S WORST IN THE COOL MORNINGS. I READ THE POST ABOUT THE LS400 CAP. PROBLEM HOW DOES THIS APPLY TO THE SC400. THE DASH IS A LITTLE DIFFERENT THANKS IN ADVANCE

It was three capacitors two of which was 25v 22uf and the one was 25v 6.8uf , they cost about 99 cents. I couldn't find the exact size so i went to radio shack and came as close to the same uf as i could. the three caps was location on the speedo guage itself. the lamps i got from the lexus dealership they was about 4.71 a piece part # 83119-24570 at reinhardt motors 720 eastern blvd. mont. al. 36117-1913 (334)272-7147
