Toyota Corolla 97 I've had a couple difficulties with the instrument cluster recently, but I'm not sure whether they're more than that. I'll be driving when the speedometer suddenly drops to zero and then rises again. Sometimes it will go to zero and stay that way for a long, and the off light will blink on and off. Even though the automobile is traveling at a constant pace, the engine may rpm when this occurs.
Thank you for reaching out. We do fix Clusters and also Millage corrections Here is the link https://www.upfix.com/product-category/repair-return/icp-instrument-cluster-repair/
They couldn't discover anything wrong with it when I took it to the dealer. I don't know what to think. They claimed that the speed sensor had been thoroughly examined.
I'm completely stumped.
