2002 Buick Rendezvous Q&A

2002 Buick Rendezvous Question: My fuel gage is being very erratic.

Says it's full, when I know it's not. Another time says it's empty, when I know it's not. It's usually saying one or the other. I keep track of my fuel by the mileage,trip meter. What could be the problem? -
Answer 1
either the fuel sender unit is bad or the connector under the back door on the drivers side. it is common for this connector to rot out over time. Roy -
Comment 1
Is this connector by the l.r door inside or under the vehicle? -
Answer 2
I had the same problem. they had to change the whole front dash panel of gauges. about $300 or so to do it.I think it was the computor system. had dealer repair. -
