Air blowing rear, but nothing in front vents. Final State Resistor

[rlteee]

I replaced my AC compressor and belt last week and yesterday my front vents are not working properly. The rear vents are blowing air both hot and AC cold, but the front has no air coming out. I checked the settings on idrive and its all correct. Based on forum research the culprit is most likely the final stage resistor. My question is which one do i get? I know the older models of the x5 use the one with a lot of spikes sticking out, but when i search for the e70 it shows two.

Which one do i get?
