hi i had the same problem on all the gauges they blocked and then you hit the dashboard with your hand on the top and they work then when you switch off they get stuck again. what i did i got the cluster out opened the glass or palstic infront firs ti put some silicone spray then some penetrating oil. be carefull no to leave oil on the dails as it will look stupid. till ow they are still working very well and they have been working for 3 months now. sometimes I think is is also when the air is cold maybe -0 degreesC
i realise that in the cluster there is humidity it might be because of that too.
