I have a 04 GMC Sierra 1500. Here’s the problem: My instrument cluster has gone out completely. Took it to a cluster repair shop, they replaced the gauges ect on the cluster. Worked great for 2 months. Now its no longer working yet again and now there is a parasitic draw that seems to be coming from the cluster itself. So here is my question: Should I just go ahead and buy a new instrument cluster and replace it myself (save some dough and pray it works) or take it to a mechanic and have them diagnose/repair/replace? How much would i be expecting to pay for a mechanic to diagnose and fix?
