Default Tach fuse keeps blowing

1989 Mustang #18 position fuse keeps blowing. Fuse is for tach instrument gauges ac clutch seat belt chimes etc.

I've unplugged the ac compressor seat belt etc still blows fuse as soon as switch is turned on. Only thing I've not unplugged it instrument cluster.

Any ides ?

Problem fixed...
Glove box light fell apart and the contact was grounding out against the metal frame of the dash blowing the fuse. I spent several hours tracking this one down

Thanks ! And yes it is

Only wish I'd found it before I tore my whole car apart
