Not all the time, but when I would drive over an overpass, mahole, or pothole, all dash lights(symbols, i.e.ABS/Parking Brake,etc) would stay on for a few seconds, gauges go from max to min a few times, and clock will reset to 12:00. Mechanic changed the alternator, but when drove over bump, still had the problem.
All of my Cluster gauges quit working. The mph, fuel, temp, battery etc. This seems to be a common problem for a Chevy Avalanche but I don't see any recall on it. Does anyone know if there is one?
The dash cluster no longer works normal. Sometimes it does and then it will not. Very aggravating and unsafe. Chevy needs to do a recall and repair these for us. It was already fixed once and does not work again. I do not know how fast I'm going, how much gas my truck has or if it is overheating.
Cluster Gage's fail on tach, speedometer, fuel, voltage, temp meters. Had it repaird at dealer twice. Went bad after each repair. Finally I fixed it myself by replacing the stepper motors inside the cluster. Bought on Amazon for $24.00 for six motors. It works perfect now
First the oil pressure gauge stopped working. A few months later the fuel gauge stopped working. I need a solution other than the Chevrolet dealership.
My gauges do not work at all except water temp...
new cluster replaced,common problem
Started with speedometer going erratic. Now doesn't work at all.
May 2004 Chevy Avalanche speedometer start registering 70mph while in park. I would turn it off and back on to reset. Now it doesn't reset. I've heard that there was a recall on this item, but I've never received anything. I'm I stuck with the repair bill.
Gas Gage does not work and shows over full when adding fuel
Tachometer and amps meters don't work
Sometimes it works sometimes its 20 miles an hour off sometimes not at all
Tachometer and speedometer both jump erratically at the same time when driving. When stopped the speedometer shows 30 mph and will increase as the rpms go up. Changed out cluster panel with a used one. No help. Problem seems to be somewhere else. Any help would be appreciated.
Entire intsrument cluster went dead started with some erratic behavior now completely dead
Oil pressuer went first, then tachometer , now speedometer Not fixed yet
Speedometer sometimes work and sometimes not. Also, when it does work, it's not accurate. I could be driving about 25mph and it would show 40mph or do icing on the freeway keeping sped with everyone else and it would show 90mph or sometimes 20mph
The speedometer and the engine tacometer quit working not quite at the same moment but close to so. the engine kept running and so did the car but no knowledge about speed or RPMs. Later after the engine had been turned off everything worked fine again
Stated that the cluster needed to be replaced because it was bad and it was burning out the weakest sensor, which in turn was shorting out all the other sensors. Paid out the high dollars and issue still existed and sensors continued to get burned out. After paying for all new sensor, then I was old that cluster needed to be reset and reprogrammed. Paid out the funds for this as well still had issue. After several visits and missed worked hours and expensive repairs took to dealership. Dealership stated needed to reprogram cluster. Picked up truck, turned right back around in less than 5 miles system did the same thing. Picked up again, stated it was the ABS disconnection, which had been disconnected for over two years. They wrapped the plugs, reprogrammed the cluster. I picked up again, and turned around to have fixed for same issue. After third time the issue was fixed. Dealership stated it was a short caused by a pinching of a wire against metal when catalytic converter was replaced, but they would not write that down on the maintenance repair sheet and they did one of those could have kinda maybe statements after I asked for it in writing so that I could take the diagnostics back to the other garage to fight for a repair reimbursement for all the parts and labor on sensors replacements caused by the short due to the bad install of the catalytic converter which the garage said they would give me if I had the dealerships written diagnosis.
the speedomer, and other gadges sometimes do not mark correctly and I have turn off engine and turn onn again
