Gas gauge bouncing during idle, not accurate at all and driver side heated seat not working...i only checked the fuse on that.

Hello, you didn't mention if the seats are power or not. If power, do you hear any clicking when you push switches? If not blown fuse for drivers seat. If not power seats than cable for locking mechanism broke or came off and won't unlock seat from current position. Your sending unit inside your tank is faulty, most likely. It is due to faulty or bad connections on sending unit which in probably attached to fuel pump inside tank. My gauge moves alot when I drive and I replaced my
pump/sending unit 5 times already. It's just the way they are making them. The only time I get an accurate reading is at a stop or smooth road.

check the fuses. they are under the back seat just pull up on the lower part of the back seat and it will come out. fuse box is on the drivers side. check to see if water is getting in that could be the cause.

Try looking at the fuses in the fuse box some of them might be blown and if they are then you probly have short somewhere in your car (replaceing the blown fuses might help)

mirrors you can adjust by hand(press left side or right side to move)
heated seats you can live without.
cigarette lighter ...no comment.
push one front corner down hard and let it bounce up,it should only bounce up then back to normal height.then do other side if either corner continues to bounce then you need to replace BOTH struts.

It might not be anything wrong with your fuel sending unit. Keep an eye on your other gauges. I own a 2004 Pontiac Bonneville GXP. All of my gauges have started acting erratically. It started with my Temp. gauge, moved on to my speedometer, and now my oil pressure , fuel level and batty volt gauges are affected too. Its a very common problem with GM vehicles.

check the fuse on the panel, the fuse panel are located in the driver side right by the panel,and check the wires under the seat.

I have a 2001 and just replaced the fuel pump assembly in the tank because the fuel gauge didn't work or worked irratic. After talking to the partsman it sounded like this was common. The contact for the sensor wears away and looses contact. You will see that the new fuel pump module has different type of metal wiper contact. As for the heated seats, I have an issue with driver side also and haven't had a chance to look into it yet.

premium gas is a waste of money. domestically produced and sold cars are actually calibrated for econo gas. well, based on what you told me and the type of vehicle, i'd invest in some well-needed maintainence (COMPLETE tune up with AC Delco platinum plugs, fuel filter, air filter, pcv, cap and rotor) don't skimp on cap quality either- told ya -they're problem-prone. BUT with the "check gauges" light coming on, my bet is you're experiencing the warning signs of imminent fuel pump failure. gas gauge been bouncing or not reading accurately?

ok`heres what you do .... you have the fuse box on the back seat take the seat of and then the box thats on the side of the battery take the top of and then go to the small fuses and check all of them there should be one or two that are burned that why the .... or it just need a little push downwards so that`s one solution check it out....

I have a 2003 chevy 2500HD extended cab that the right side window, seat heater, seat controls, door lock, will not work. all other windows and door locks work. I checked all fuses and they are good. what can it be.
