Air con issue

[Lukem10]

Anyone had issues if their air con clicking all the time when on?
I can hear what I think is the compressor clicking ever few seconds....it's not as cold either through the vents but was working fine a couple if days ago.

Just had a little look at it and play around.
If I start the air-con with the fan set to low (first 3-4 bars) then it's fine and it clicks in and starts working fine. I can then turn up the fan speed all the way to last but one before its full blast and works fine. As soon as I put the fan to full it starts clicking in and out every couple of seconds...like its too much for it to handle.

Anyone had anything similar?
