Dashboard clicks

Thought I'd have a go at getting the centre consol apart and try and find my clicking modules. It only does it when the outside temperature is hot and this year it's annoyed me one too many times!!
I got the side panels off and I could see a connector haging loose. Re connected it and hey presto....two clicks!! Finally got it up to three clicks - all the previous owners have done is unplug the noisey ones!!!
Finally got the consol out the way (No idea what I was doing. I'm used to the meccano kit that is a Mk2 Golf!!). Now I've got to wait for it to get hot again so I can track the click down!!
I end with guessing the modules are quite expensive and non repairable?
