I have a 2005 Tahoe and it's got two issues
1 the fuel gauge quit working
2 it shifts into 4 high but will not shift into 4 low and the service 4x4 message is being displayed on the dash
What are my remedies for these
Please if anyone can answer I would greatly appreciate it

 

Welcome from Florida. To fix the fuel gauge you will have to replace the sending unit in the gas tank. The best option is to replace the fuel pump assembly as the labor is the same and depending on how old the pump is, it could fail shortly.
