HTR Sub1 Relay
NOTE:
HTR SUB1 relay may also be referred to as heater sub relay or heater relay.
- Remove HTR SUB1 relay from fuse/relay box located at driver's side front corner of engine compartment, just in front of strut tower. See Fig 1.
- Note terminals on HTR SUB1 relay. See Fig 1. To test HTR SUB1 relay continuity, using ohmmeter, check that continuity exists between terminals No. 1 and 2 on HTR SUB1 relay and that no continuity exists between terminals No. 3 and 5 on HTR SUB1 relay. If continuity and no continuity are as specified, go to next step. If continuity and no continuity are not as specified, replace HTR SUB1 relay.
- To test HTR SUB1 relay operation, apply battery voltage and ground to terminals No. 1 and 2 on HTR SUB1 relay. Using ohmmeter, check that continuity exists between terminals No. 3 and 5 on HTR SUB1 relay. Replace HTR SUB1 relay if continuity does not exist between terminals No. 3 and 5.
