The relay in my control unit failed this summer, but since my unit was perfect otherwise I decided to replace the relay vs getting a rebuilt unit.
I know the stock relay is under rated for the 3 amps that the compressor will draw, but the first one lasted over 30 years, so this one should last until I'm 87 at least. LOL
Semi-retired, as of Feb 1, 2023.
The days of free technical advice are over.
Free consultations will no longer be available.
Will still be in the shop, isolated and exclusively working on project cars, developmental work and products, engines and transmissions.
Have fun with your 928's people!
As the wiring, connectors, the freeze switch, and the magnet for the clutch age, the current draw goes up, not down.
A slightly higher amperage relay than stock might be better?
Maybe, but it was a choice of $70 cdn for the relay from Germany or $550 cdn for a rebuilt unit from the US. I will report back next summer if it fails or not.

Wow.
Certainly the least of both evils!
