what should be done while dash is off?

[Konstantin Bogach]

Hi listers.

I took dash off to get better access to instrument panel connectors. I
have not idea how people could disconnect those connectors without
removing whole dash! But anyway, it is 2 hours job if you do it 1st
time(but know what to do).
I do it cause speedo jumps plus-minus 10mph.   I have no idea what might
be the reason but I had time while I wait for new rear control arm to
come.  I am thinking about cleaning connectors and checking soldering in
the place shown on SJM site.
Can somebody add something else?

What useful can be done while dash is off. I could think about ambient
air sucker only. But I am not sure at all should I do anything or not.
How often they go bad? Can some maintainance be done to this pump/motor?

Any input will be appreciated.  I am deep in unknown and maybe hostile
(if it is easy to screw thing up) teritory.

Thank you.

wait to be tested. And all this wait just because protective boot on
rear control arm (new) was ripped! Sh#%^!)
