What amperage relay do I need?

[BSK]

The Hi setting on my ac fan wasn't working. I swapped the relay with the rear demister relay as they are the same part number. The Hi setting now works! Sweet.
So obviously I need a new relay. It is a 4 pin siemens relay, they are all through the car but no amp rating on any of them.
40amp is my guess as the fuse for the blower is 40A.
Anyone know how many amps this should be?

Part number is V23134-K52-X277
