Hi, I just bought a 92 Sc300 and had a few questions. I read the forums on how to fix the lights on the clusters when they go out, but my RPM neddle doesn't work at all. Does anyone know what the problem is and how to fix it? Should I just get a new cluster instead of going with lextech? Does a SC400 cluster fit in my car?
How much would it cost to replace my wiper regulator? The wipers don't go all the way down when they not in use and it gets stuck for a few seconds every time I turn it on. Any suggestions?

i had the same problems so my fiance and i went to a junkyard where they had two sc400s and we just plucked the needles out of the cluster (which was already broken), took the needles and stuck it in my car... 2 out of the 4 needles worked but the junkyard gave them to us for free. you can probably go junkyard hopping and grab a couple because some will probably not work. if you do this, be careful with the needles and make sure you have someone that knows about speedometers putting the "new" needles in... it is a temporary solution though. you could also look on ebay. they sometimes have inexpensive dash clusters and if the needles don't work, at least you will have an extra set so you can send one to lextech, get it fixed, and replace it with the one in your car.

I finally got my cluster working. A quick recap: I sent my cluster to Lextech.org to upgrade the needles to blue and the background to ultra-white. When it came back to me, all was OK except the fuel guage did not work. I was told to I had to put a new fuel guage in myself. Since I had previously bought a scrapped cluster, I moved that fuel guage over to the Lextech one. Not being an engineer, I managed to disable the Tach and water gauges. I still had blue needles, but neither the Tach nor the water gauge registered properly. I sent the cluster back to Lextech and they got the tach working, but the water gauge still did not register.
OK, the problem with the water gauge stems from the earlier fix's that this cluster has undergone. I have the original repair orders from the original owner and a Lexus dealer in this area repaired this cluster three times in 12 years. The water gauge Must have the mounting screws inserted and tightened down properly. It seems that the screws not only hold the water gauge in place, they complete an electric circuit. The screws must tighten up through a set of plastic tubes and over the years these tubes have become distorted and three of the screws would not tighten down properly to make that connection.
Here is where my mechanic comes in. He inserted a VERY fine wire down into each tube and then put the screw in and it tightened down properly. The wire acts as a Heli-Coil. (Those of you that have worked in manufacturing and/or auto repair know what a heli-coil is) Any way, the cluster is working perfectly now.
I have included a picture showing the back of the cluster and a couple of the screws so that you can get an idea of the problem. Particurlarly look at the design of the screws and you will see the need to wrap them with the very fine wire.
I hope this is clear. Others may run into this problem also.
I was unable to post a picture, It shows the problem a bit better. Just remember that ALL if the screws need to tighten down and make electrical contact. I finally put a litle spot of soldier on a couple of the screws. BE VERY CAREFUL with any soldering, you can ruin the whole cluster if you get ham-handed.
Good luck.
