FLUTTERING TEMP GAUGE I8N 2003 SATURN VUE
Well son, there are MANY reasons that might cause "fluttering" in your gauge. Mine started doing that, then I started getting a warning LIGHT for overheating. My solution for that was a fault in my fan. There are 2 speeds on my VUE'S electric fan. The one that required attention was speed/high (the speed/low was working). If your getting an intermittent short, watch both the temperature and fuel gauges to make sure it's not a real (both will do the "fluttering at the same time if it's faulty short) overheating problem. If you have an OCD-2 reader, plug it in under the driver's dashboard and go to function "live" read the engine temperature. If that's normal it will be between 120F-200F.
Faults may be relays in the under-hood fuse panel (there either good or bad, you can't see anything like other fuses) and there are the 30 amp or 10 amp fuses inside the same fuse block for that electric fan.. I've found that if I open the hood and start your car, after it warms up, there are tree things that could happen.
1: the low fan starts up, then start your A/C, the high fan speed comes on (normal, check your temp gauge).
2: After you warm it up, the low speed fan starts up, but with the A/C on, the high speed fan isn't coming on (bad high speed fuse or relay).
3: after warm up, the low speed fan doesn't come on, but starting the A/C the low speed fan comes on (bad sensor I think).
I've had a ghost in my VUE since I bought it, gone through 3 computers, CVT sensors, key won't turn without destroying the key. One time, I used the horn to get some deer off the road and the damned thing wouldn't shut off. While I was under the hood trying to get it to turn off, TWO cops stopped, they shined their flashlights on the fuse block and one on the diagram for me to pull the right fuse. I took it out, plugged it back in and it worked again! The shop didn't find a thing wrong with it, but the thing works still.s
