Klima
The Klima relay (Behind the plastic "wall" behind the Battery) will compare the
Tachometer signal with the speed signal from the back of the Air Conditioning
Compressor...and if there is too much difference No A/C.
So...Fixing your Tach signal May give you Air Conditioning again.
The OVP relay is in the same area behind the plastic wall.It's only job is to
protect the expensive "Brain" type components (EDS[engine computer],Cruise
Control,and Air Con CCA) .It will be a silver relay with at least one 10 amp
fuse underneath a red plastic cover on top of the relay.
Looks like this:
