I just put my car back together and I was able to start it, and everything was fine. I just moved the vehicle out of the garage and parked it. Two days later I started it up to run some errands and my instrument panel reads power steering, Coolant gives three different temperatures, my speedometer and RPMs are not registering. Everything was fine when I first started it and moved it out of the garage. Can you help me with where the fuses for the speedometer and RPMs and what should I do about the power steering even though it's working.

If you're experiencing issues with your instrument panel, specifically the power steering warning, erratic coolant temperature readings, and the speedometer and RPM not registering, there may be a few potential causes. It's important to note that without specific information about your vehicle's make, model, and year, I can only provide general guidance. Here are a few suggestions to help you troubleshoot the problem:

Check fuses: Start by inspecting the fuse box in your vehicle. Look for any blown fuses related to the instrument panel, power steering, or other relevant components. Consult your vehicle's manual or the fuse box cover for the specific fuse locations and ratings. Replace any blown fuses with new ones of the appropriate rating.

Battery connections: Ensure that the battery connections are secure and free from corrosion. Loose or corroded battery terminals can cause electrical issues and affect the instrument panel functionality. Clean the terminals if necessary and tighten them securely.

Wiring and connectors: Examine the wiring harness and connectors related to the instrument panel, power steering, and engine sensors. Look for any visible damage, loose connections, or disconnected wires. Make sure all connections are properly secured. If you find any damaged wiring, it may need to be repaired or replaced.
