Thank you for the suggestion, blue62. I will double check the fuses, relays and wires based on your feedback.
Based on the fact the instrument cluster is sending fluctuating signal (received by the climate control at B13 wire), I guess I should expand my search to include the instrument cluster system as well.

Yes make sure your ground point is good as well as the ground wire and it's connection point at terminal 31. It also looks like B13 has a connector where the wire changes color from yel/blu to orn/grn...so you need to check that connection as well as everything along that wire.
