A/C Clutch Relay (Except 3.5RL)
WARNING: This page is about a different car, the 2004 Acura 3.5RL, 2003 Acura 3.5RL, 2003 Acura 3.2TL, and 2003 Acura 3.2CL. However, it is still accessible from the selected car via links, so may be relevant.
NOTE:
On MDX & RSX models, this type of relay test is also useful when checking Ignition Coil relay, Air Fuel Sensor relay, PGM-FI main relays 1 and/or 2, and Throttle Actuator Control Module relay (MDX only).
Relay is located in underhood fuse/relay box. Remove relay. Check continuity between terminals No. 1 and 2. See Figure . If continuity is present, replace relay. Using fused jumper wires, connect 12-volt battery power and ground to terminals No. 3 and 4. If continuity is not present between terminals No. 1 and 2, replace relay.
