2003 envoy inside electric doest work,ichecked all the little fuses and thier good. the truck starts and the wipers work and the headlights work.It started when either i jumped the battery or when i replaced the battery.
I assume you are saying the gauges aren’t working. This could be due to a faulty ignition switch or power connection to the cluster. It would be good to verify that power is really getting to the fuses by using a test light probe. The fuse may be good but if no power is getting to it you get the same results as a bad fuse.
The gauges work its the inside lights,sunroof,air,seats and radio.
