BMW: fuses?, 1989 bmw 325is, bmw 325is

Question
i have a 1989 bmw 325is. the tack, the left turn signel(only on the gauge),and the mile per. gallon gauge is not working. i don't know if it is fuse or something els.

Answer
Travis,
 The problem is most likely in the cluster.  These instrument clusters are notorious for having issues like this.  I would remove the cluster, clean some of the contacts for the guages and lights, and that should have you set.  If not, you can purchase another used cluster on Ebay.

 Good luck,
 Josh
