#2 of 34 Dashboard lights don't light up by oldestbrosteve Oct 04, 2006 (4:28 pm)
I've got a 94 LS 400 with 130,000 miles and lately the dashboard lights won't come on unless it's warm outside or after the car has warmed up quite a bit. With winter coming soon warming the car enough may not happen since I only drive about 4 miles to work each day Since the gas gauge stopped working about 3 years ago I use the mileage and the low fuel light to tell me when to fill up. Without the lights that makes it near impossible to know when to fill up. Anyone with ideas?

Replying to: oldestbrosteve (Oct 04, 2006 4:28 pm) Yes - Fix them, or get a new car. (sorry, couldn't resist when you lead with your chin... ) I don't know how to fix that problem, but I do think you can fix the gas guage.

Replying to: oldestbrosteve (Oct 04, 2006 4:28 pm) I really do think fixing the dashboard lights would be a good idea, since there are other warning lights that are, IMHO, essential. Since they do come on after the car is warmed up, perhaps the repair would not cost much?   OTH, there is the low-tech way a former co-worker used: Keep a written log of last fillup and miles driven since then, provided your odometer still works. You'll need to know the MPG you're getting, and then do the math.   My '05 LS has a digital LED readout on the odometer requiring dashboard lights ... I don't know about the '94 LS.   Old age is rough, isn't it, even for cars.

Replying to: oldestbrosteve (Oct 04, 2006 4:28 pm) See message 2072. bba-reman.com has the solution. I am sending my 95 LS 400 instrument cluster there. regards, cinci1 Replies to this message: pat (Oct 30, 2006 9:49 am)

I am new to this computer stuff so bear with me. My 93 LS 400 Lexus (164K miles) has problems with the instrument cluster. In cold weather the display does not light until it warms up (4 miles of driving usually does it until the AM temps are 40F)in So Cal. Every one agrees the solder traces have micro cracks and expand in cold weather and reconnect once warmed up. Solution: bba-reman.com offers to rebuild your unit in 2 days and send it back to you. It costs about $175.00. I am sending in mine Nov 4, while on vacation, my mechanic will reinstall it. They even send you a simple diagram on an easy removal process. For LCD leakage: lexsteam.com offers solutions and LCDs. Replies to this message: tjpatpdg (Feb 09, 2007 9:29 am) pat (Feb 09, 2007 9:47 am)

Replying to: cinci1 (Oct 25, 2006 5:07 pm) I just read your Oct. 25, 2006 posting. I recently bought a 1994 LS400 with the same problem. How did your solution work? tjpatpdgyahoo.com Replies to this message: pat (Feb 09, 2007 9:47 am)

Replying to: oldestbrosteve (Oct 04, 2006 4:28 pm) go to the auto aftermarket place, they have the fuse or part that you may be able to change yourself. You have 130,000 miles that is great I had 160,000 on my GS 300 1998. They dont make them like that anymore. My new 2006 GS430 is poorly constructed (plastic almost), I dont know if it will last, I may move over to Infinity. Hope the auto parts store answers your question or at least helps. JS
