If it is a blocked jet you can reach it by spreading the wiper cover sides gently apart (tryone side at a time) and pop it off. The double jet head is just pressed in like a ball and socket/cup. It doesnt look like it would stand up to too many strip downs.
If you strip it down make sure you give a good squirt out to clear the line while its open.

Of courese all this assumes its the same/similar as Q7
