started working on a ssr fuel gauge needle is pointed at the 6 o clock position at all times. looked in the verus no bi directional test for a gauge sweep. but looking in the data display under fuel level input it read 22% so that tells me the sending unit in the tank is fine. are these clusters hard to repair? if they are installing a new one isn't an issue. as I have programming capabilities
also had a 2000 grand prix the fuel level input read 58% rock the car sideways a little and it went up to 200% pegged the needle out to the stop on that gauge. tank need pulled to put a sending unit in? or do they have an access port?
GM had lots of trouble with potentiometer in level sensor. If you can test the line it would help.You can replace just potentiometer itself if that's the case

Hey Cheryl, glad to see you on the new forums!
I've never tried doing gauge repairs on these clusters, only replacement. Given GM's track record for gauge problems, I'd probably opt for a replacement assembly.
No access port for the 2000 Grand Prix that I know of If you're gonna do just a potentiometer, you might scope the motor with a current probe, just to check for any obvious pump problems.
been pretty busy with the mobile work lately! especially with gm's had a Yukon last week had a serial data bus issue with no windows, mirrors, locks, adjustable pedals. needed a new drivers door module. seems like a basic test snap on left out on the gauge sweep test on the ssr though!

Ahhhhh, but where would we be without the steady work that GM's provide?
No joke about the gauge sweep, I've been able to do that test as far back as 2001 on some trucks. Maybe try telling the scanner it's connected to a Silverado or a Sierra? I've had luck doing that with Isuzu's and Mazda's, looking for functions that should be there, bur aren't.
