Guys,
I had all kinds of problems with my 94 Lexus LS 400. My backlighting was flickering, the needles on my tach and speedo were half-lit and they were off totally. Luckily I found this place right in town, DNA Speedometers! I can bet you its cheaper than Jim Walker and professional. You actually talk to somebody and they have a phone number which is hard to find these days.
Good Luck,
Tommy
