Yep, easy.
Torx screw holding door handle with mirror adjust/window switches in.
torx screw holding door opening silver handle.
four torx screws at bottom of doorcard.
little triangle interior mirror cover pulls off.
so does door trim by b pillar.
Door card itself is held on by poppers and butyl. ease it off starting from bottom. then slide it out of the lip at the window seal.
Most likely the handle linkage has shat itself.
If you want me to have a look, i'll have the parts to fix it- bring it to Chertsey on Saturday and i'll get it working for £30.
