Boot Difficult to Close - Latch Motor?

[chrisc201]

Gents,

Done a fair bit of reading and can see it's a common fault but not what the order of fault resolution normally is....symptoms are;

- power close drops boot down then hear a motor whirring as the right hand side goes up about 1cm, then stops and boot hasn't latched
- right side of boot sits high regardless of manual / power close
- closing boot manually requires a decent slam to get it to actually catch
- power open only works when you give it a little head start and lift it about an inch, believe this is a seperate issue

So far I've cleaned and lubricated all the struts, hinges and locks then yesterday I pulled off the plastic panel that covers the latch (just above bumper in middle of car) to check the spring, no obvious issue and appears under tension.

From reading I gather there is a latch microswitch and latch motor that are both the potential issue, any advice on how to work out which is the issue and how to replace appreciated!!

Thanks,
Chris
