Take everything out above and below is great advice, that is the way I did it. Then I found where the top two spring clips on the climate panel are and pushed each one in turn with a small thin screwdriver. Remember to put a spot of 3 on the shaft of the screwdriver once you have the spring clip depressed and watch the bead of oil get delivered to where you require it. You could just blast spray on the spring clip. Now rock each side back and fourth to work the oil in. Your ready to remove the unit as Audifan explained above.
Once removed clean the oil up with a rag. Job done. ?
