WARNING: This page is about a different car, the 2011 Suzuki SX4. However, it is still accessible from the selected car via links, so may be relevant.
NOTE: Do not use blue relay for the substitute of white relay because internal durability of a blue relay is different from the durability of a white relay.
  1. Disconnect negative (-) cable from battery.
  2. Remove compressor relay (1) or condenser cooling fan relay (2) from main fuse box (3).
  3. Check that there is no continuity between terminal "c" and "d". If there is continuity, replace relay.
  4. Connect battery positive (+) terminal to terminal "b" of relay and battery negative (-) terminal to terminal "a" of relay, and then check continuity between terminal "c" and "d". If there is no continuity, replace relay.
