Fuel gauge, temperature gauge and speedometer not working in dash. New cluster was put in and still nothing. Took out backhand cleaned connections. Still not working? BCM?

Hello,

I would do a power and ground test to the cluster to start. Here is a guide and some wiring diagrams to help get you started:

and

If everything checks out here is the location of the BCM

Please run some tests and get back to us we are interested to see what it is.

Cheers, Ken

Thank you for the detailed diagrams. I purchased a manual for the car but it does not have the grounds listed. So thank you! I will take your advice and let you know what happens.
