Climate Control light for 2000 Jetta

Hi there,
I am novie at thesethings.
No light is appearing to display my climate controls therefore cannot
see them at night. It is interesting to note the A/C and recyvle
button light work at times.

Assuming the problem is just a bulb, how do I change it? Is it too
difficult for someone like me?

Also, anyting else it might be (if I am wrong about the light)?

Cheers, and happy New Year all
