Does anyone know why i cannot see serial interfaces on a WIC 2T module inserted on a C2821 router.

Hi there,
If you do "show version", does the router list "2 Serial(sync/async) interfaces"?
Have you tried the WIC in another slot (or, if possible, another router)? If there is a hardware issue, it would be good to try this to rule out either the router or the WIC as being faulty.
Kind regards,
Graeme

No it doesn't display the serial interfaces.
The module has been tested okay on another box (2621), but no slot in this particular box (2821) can see it. Other modules (like vwic 2mft-E1) is currently producing in the box. See output below.

Please send "show diag".

All C2821 4 on-board slot is for HWIC, so it shouldn't be a problem which slot you put the WIC-2T card. Its different for other model though.
Can you post the complete output of "show diagnostics"?

Also, you can observe the output from these commands:
- show inventory
- show diag
HTH.
