190D A/C not working

1984 190D, recently bought with A/C non functional.
Compressor not kicking in.
Static pressure in A/C reads 90psi.
No voltage at pressure switch.
Removed KLIMA Relay, and bridged the #5 and #7 pins, and Compressor clutch locked and kicked in.
Cold here tonight, so could not feel cooling effect at vents...
Is this as simple and a bad Klima relay?.
