There are a number of things that can cause the heated seats and power seats not to function. You have confirmed the fuses are OK, now you need to confirm the ground circuit is good.
The G305 ground circuit is located either under the driver seat and carpet or at the left lower "a" pillar under the carpet retainer trim in the driver door opening.
The G305 ground circuit is tied to both the heated seat and power seat issue.

You may want to have the truck scanned for diagnostic codes. You can have this done at no charge at your local Auto Zone. It may narrow down the problem a bit more.
The reason I say that is the switch that controls the heated seats and power seats sends a signal to the Driver Door Module located in the drivers door. The DDM then sends a serial message to the seat control module and the seat module then performs the command. So if the message is not received by the seat module, hence, the seat does'nt work. So the problem could be with one of the other modules.

Check the ground and if it is OK, have a code scan performed and we can go from there.
Good luck.
Regards,

{: ) If you are referring to the IPC message screens going blank, and the gages and warning indicators seem to be working normally, the problem is not the fuse but an IPC internal circuit fault.. So better be ready for a new one. A replacement IPC will be that of later model versions. It will be programmed to your vehicle, and the mileage record will be reset to zero.

{: ) It will be helpful if you can elaborate more on this concern and also note down any other symptoms that you may notice. It's because there are many GM bulletins that may apply to your problem.
Anyway we can just round off some possible causes and fixes for the moment.
If only the DIC screens on your cluster are going dim or blank despite adjustments on the backlighting knob near the main headlamp switch, the problem is internal to the cluster, and it can be fixed by an electronic service center. The other option is to have it replaced and programmed.
If the DIC buttons doesn't seem to work, remove the DIC connector and check the black wire for a good ground connection. You may also try removing the IPC fuse at the underhood fuseblock for 20sec while the igntion is off. Then reinstall the fuse and turn ignition on, and recheck button functions.
Another option is to diagnose the DIC inputs and cluster operation using a GM scan tool. It can monitor better the signals from your DIC. The scan tool may also reveal some codes that can be relevant to solving the problem, like a wiring or a component issue.

Does a weak alternator cause DIC panel to be dim or out?


No. The cause of a dim or dark driver info display is a weak/broken solder connection, usually one or more resistors/rectifiers, on cluster circuit board. An electronics repair service that specializes in cluster repair can usually correct this issue and usually at a reasonable cost compared to replacement cost at you local GM dealership. Good luck.

2009 chevy tahoe RAP is not working. radio and dash cluster back light stays on when driver door is open.


{: ) If your vehicle is equipped with a DIC button, try to press on the button if the lights goes off. Or better yet, remove the connector of the DIC button. If the problem is eliminated, then you may need to replace the DIC button.
Another possible cause is when there are issues with the driver door and the body control module (BCM). The only door that can turn off the radio during RAP is the driver's door. It's possible the door is not giving the proper signals to the BCM. Or it could be the BCM is at fault, some stuck up internal relays or a software issue.
In this case, a scan tool can effectively monitor all these inputs, and eventually speed up diagnosis and make the necessary recommendations.
