i have a 2005 scion xa and when i bought it, it had 160k and the cluster has been giving problems. Randomly the rpm tach does not work and stays at 0 and most of the time it doesnt work correctly like when its at idle it shows 200 rpm. i was wondering if anyone had this problem. my brother told me it was probably old or defective. i have taken out and clean the connection and tried other steps but nothing has fixed it. also some time the gas gauge will go to empty when i start it up and take about 15 mins to go to the correct amount of gas. i was wondering if anyone has another cluster for sale for cheap. not trying to spend so much. thanks for you time
