No, the tach doesn't work. But the a/c was working without the tach as soon as the new stuff was installed. My parts supplier tells me the tach does need to work in order for the a/c to kick in on this model.
I really do not need all the bells and whistles the Klima is supposed to offer. The pressure switch will protect the compressor. I have wired the aux fan directly into the compessor blue lead.
I do need a/c. Any ideas on which pins to jump to get the a/c clutch on. Then I can work backwards to wire in an ice cube relay that will kick in the clutch. Simpler is better!
