My 06 with 124,000 miles just starred having an issue. I initially thought it was the junk gage cluster,gm used, going bad. My tach bounces, I will randomly lose other gages, fuel, oil pressure, temp, ect. When this happens, I also lose my AC. Another weird issue, while rolling up my passenger window it cuts in and out, it will go up, very brif pause and then continue, then do it again, sort of srudder. Anyone have any ideas?

Your 06 what? It certainly isn't an f-body so it would be helpful to know what model.
