AIR CONDITIONING SYSTEM — Relays [Diagram showing Magnetic Clutch Relay with terminals 1-4 and Fan Relay No. 1 & Fan Relay No. 2] Fan Relay No. 3 [Diagram showing relay terminals 1-4 with coil] [Diagram showing Heater Relay terminals 1-5] [Two diagrams showing continuity testing points with numbered terminals] 2. INSPECT RELAY CONTINUITY (Magnetic Clutch Relay) (Fan Relay No.1) (Fan Relay No.2 ; 7M-GTE E/G and A/T Model) Terminals Condition | 1 | 2 | 3 | 4 Constant | [continuity symbol shown between terminals] Apply battery voltage to terminal 2 and 4 | [continuity symbol shown between terminals] (Fan Relay No.3 ; 7M-GTE E/G and A/T Model) Terminals Condition | 1 | 2 | 3 | 4 Constant | [continuity symbol shown] Apply battery voltage to terminal 1 and 2 | No continuity If continuity is not as specified, replace the relay. (Heater Relay) (a) Check that there is continuity between terminals 1 and 3. (b) Check that there is continuity between terminals 2 and 4. (c) Check that there is no continuity between terminals 4 and 5. If continuity is not as specified, replace the relay. 3. INSPECT RELAY OPERATION (Heater Relay) (a) Apply battery voltage to terminals 1 and 3. (b) Check that there is continuity between terminals 4 and 5. (c) Check that there is no continuity between terminals 2 and 4. If operation is not as specified, replace the relay.
