2 radiators wont work!

[RstJAB]

There are 2 radiators in my flat that will not work, the boilers is firing / working fine and the other 4 radiators are fine (although they do whistle a bit). I have bled the 2 that don't seem to work and there is no air in them.

Does anyone have any other suggestions as to what I can do to try and fix this before my girlfriend moves out as it is so cold?

Thanks in advance

Turn all others off and then open 1 suspect one. If it heats up, open the other one. Could be an airlock which will be pushed out.
If they still do not work, suspect a blockage somewhere. By feeling the pipework to see if they get hot should point you in the right direction.
Could equally be Trvs stuck or rad valves blocked.
Do some detective work.

the pin is stuck in the rad valve

Whilst that sounds very painful, I'm not sure what you mean, please can you elaborate a bit for me
