I get some cars with corroded contacts at the instrument cluster plug, that
long one with about ten contacts.  There can be all kind of dirt, oxidation
or the plug side not touching it strong enough.  I lift those little arms
inside the plug and clean the contact areas on the instrument's foil.
Suddenly all kind of lights work properly and some that never worked now
it's there.
This maybe one reason why there is no proper response.
