Temp and Fuel Gauges and Heat/AC Fan all went out

[Humanpowered]

Hi All,

I have a 90 325i convertible and the temp gauge, fuel gauge and heat/ac controls all stopped working at the same time. I've searched and haven't found this issue posted elsewhere. I'm wondering if anyone has any idea what could have failed. I've checked fuses and ground and not the issue

possible temp and fuel gauge could be related to an issue with the cluster, heat and ac are gonna be something separate.
