07 camry dash guages not working

[Chrisb_75]

ok let me start by saying it only the heat, tach, rpm and speedo that dies.. im in canada so its cold and when i start the car in the morning it works fine untell the car warms up or if its really cold it works fine... ive tried a new cluster and the same problem.. i was told by the dealler it may be a ecu problem so put in a used computer and nothing.. im thinking there maybe a relay thats acting up but when i ask the dealer anything about this car thayre not much help if any.. any ideas would be great, thanks

Look for a "Can Buss" problem. The spedo and tach read that operating/diagnostic buss. Probably a loose connection at the junction connector hidden inside the dash.
