The lights on the odometer on a 1999 Chevy Blazer might not work because of a burned out fuse. They might also not work if the lights are burned out.
Cluster means all the gauges and warning lights on a vehicle i.e. fuel gauge,temp gauge speedometer, odometer, oil pressure warning lights etc.
remove dash replace bulb(instrument cluster)
Turn the brightness control up. Could be the reset button for the odometer or another switch.
Well, not exactly. If the rest of the cluster gauges and lights are working, the cluster is working. Seems obvious, but I understand your question. This may or may not indicate that more cluster failure is imminent. There have been several questions about the cluster, many of them asking specifically about the odometer light. The generally accepted common knowledge is that the entire cluster has to be replaced when one facet of it fails. However, one fellow posted that the odometer light can be removed (after removing the cluster) and a new one soldered in it's place as a fix. I can't attest to how accurate this info is though. Someone else posted that the odometer can be read with the help of a flashlight. Not a very comforting work around, but if you need to read the OD badly enough, what the heck?!
This is a common problem on regals .There are resistors on a circuit board behind the instrument cluster that are loose or burnt out. Getting to them is tricky , there was or is a video on youtube describing the procedure , the resistors are about $1 at radio shack for a 5 pack. They must be soldered to the circuit board . I had to replace 7 resistors that were loose. The original resistors were very small and poorly soldered. My gear indicator lights and odometer numbers did not light .
I had the same issue. In the instrument cluster there are 3 boards. The smallest board with the odometer and transmission status displays also has the 4 lights for the back lighting. This board is plugged into the main board and can easily be changed. Theses lights short out and cannot be changed out individually, the only thing you can do is replace this board.
They are integrated into the cluster. They can be replaced if you are patient and can solder well. A variety of colors are available on EBay. www.trailvoy.com Trailblazer enthusiasts forum
I have the same problem a 2000 Saturn sc2 the odometer is diglital lights, regesters 50046 and does not change. Does anyone know if I can change with a junk yard cluster and have it work? dealer seams to think it,s the cluster but wants 500 dollars. would the black box send the correct milage on the car now or would the odometer show the milage from the salvage unit? Or would it not work at all. Sory to answer a question with a question Thanks all Pete
cluster lights dont work also tails ive change the light switch still no lights.
if the cluster still lights up but the speedo still inop possible cause is the speed sensor in the transmition
Remove the dash and remove the instrument cluster, the lights are in the back of the cluster.
You Will Have To Take To A Dealer. Best Of Luck
