I have a 2004 chevy Silverado 2500 HD and I got a odometer error message in my instrument cluster. Is this from the instrument recall from way back? Front left window switch works intermittently also.

Disconnecting the battery isn't going to change anything . You have a hard fault . The IPC calculates the mileage based on the vehicle speed signal circuit from the powertrain control module (PCM). The odometer will display 'error' if an internal IPC memory failure is detected. IPC- instrument panel cluster ! Is the odometer inoperative ?

2004 Chevy Silverado 2500 HD The gas tank takes forever to fill. It keeps thinking it is full. I know there are a lot of people out there with this issue. Is there a factory recall or is GM going to...

The gas tank on your truck doesn't decide when the gas pump shuts off. It sounds like you think it's not as full as it is. Make sure your looking at the gas gauge instead of the temp gauge.

My 2004 Chevy Silverado 2500HD has just begun having a sticky odometer. Only falls to 65 mph when off. Just started on the way home tonight. Any suggestions?

I would check the connection at the back of the instrument panel. And check the connector at the Vehicle Speed Sensor. The vehicle speed sensor should be located at the rear of the trans or transfer case. This is a two wire connector.
