INSTRUMENT CLUSTER

2004 Buick Lesabre

Electrical problem
2004 Buick Lesabre 6 cyl Front Wheel Drive Automatic 44000 miles

My speedometer and tachometer will malfuntion and point in all sorts of different directions and not in alinement with where they are supposed to be. They straighten themselves out after about a week but its in the mean time it's a little hard to figure how fast your going.
Currently the speedometer is pointing straight down and they tach is 500 rpms off. Is this an electrical issue or a mechanical one?

I also own a 2004 Lesabre and am having a very similar problem with the speedometer and gas gauge. The needles are wacky, but the computer appears to be working fine. The odometer, cruise control, and digital readout of fuel remaining appear okay. I'm starting to think this is a recall issue. I sure don't want to spend upwards of $400 to replace the cluster. What to do?

Stepper motors in the clusters cause this problem. It happends on all GM vehicles. Sorry Guys the only way to fix this concern is replacing the cluster. But if you are having a problem with a fuel gauge it could also be a level sensor. Keep that in mind.

Over the past month my speedometer and fuel guage has been malfunctioning also. With three comments in one month this seems more than a random problem. Is Buick helping with the costs.
