Turn signals do not work in gauge cluster but work outside

[ParadiseXJ]

In the gauge cluster:
What happens? Lights don't come on at all? Light comes on and stays on?

On the outside:
All four corners work? In the front, do the parking lights AND the side markers blink? Just the P-light or just the side marker?

If the inside lights just go on and stay on, it's an indicator that one or more bulbs/sockets is non-functional.

If the outsides work on ALL four corners (front park AND sides) then the flasher is ruled out since it's doing it's job.

Try looking at the gauge cluster fuse and/or gauge cluster ground. If the inside lights are not working at all...the gauge cluster bulbs could be out, but both at the same time would point to a ground or fuse problem....IMHO.
