My tachometer works, but the temperature, fuel and speedometer don't work. I just put in a new battery.

Welcome to 2CarPros.

Did the problem just start since you replaced the battery or is it ongoing? What I would like you to do is put the cluster into self diagnostic mode. No special equipment is needed and the codes may be helpful.

Here are the directions:

Cluster Diagnostics/Calibration
Vehicle Instrument Panel, Gauges and Warning Indicators Testing and Inspection Component Tests and General Diagnostics Cluster Diagnostics/Calibration
CLUSTER DIAGNOSTICS/CALIBRATION
SELF DIAGNOSTIC TEST
To activate self diagnostic program:
1. With the ignition switch in the OFF position, depress the TRIP and RESET buttons.
2. While holding the TRIP and RESET button turn the ignition switch to the ON position.
3. Continue to hold the TRIP and RESET buttons until the word code appears in the odometer windows (about five seconds) then release the buttons. If a problem exists, the system will display diagnostic trouble codes. If no problem exists the code 999 (End Test) will momentarily appear.
