05 Silverado Multiple Symptoms
I have a laundry list of problems that occur randomly and I think they are related.
1. turn key to start, nothing happens, not even dash lights, wait 10 minutes and it starts up fine, happened 3 times during summer 2. voltage meter: sometimes at 14, mostly past 19, needle has gone as far down as possible a few times, checked voltage at battery and alternator always at 14, battery light on dash will come on and display says "Service charging system" 3. speedometer: rarely works correctly, all others gauges work When the stepper motors go bad do the gauges work at all? 4. AC: blows cold then switch to HOT by itself, turn truck off and back on blows cold again 5. rear-view mirror: dimmed during day-light and will fluctuate back and forth in just a few seconds Any ideas? |

Could be link together. I had a new cluster installed under a service bulletin. It is a common problem. Do some searching around. It has been brought up plenty in the forum. 4. Another common problem. Make sure your A/C is serviced properly. If its not that its a problem with the actuators in the dash. Its been talked about alot in the forum. 5. thats a new one to me. good luck Hope this helps |
