Blower System: Diagnosis Kia Rio II рестайлинг

INSPECTION

Check for continuity between the terminals.

Scheme 22

Scheme 23

1. There should be continuity between No1 and No. 4 terminals when power and ground are connected to No. 2 and No. 3 terminals.
2. There should be no continuity between No. 1 and No. 4 terminals when power is disconnected.
3. If the blower motor voltage is not operated well, substitute with a known-good blower relay and check for proper operation.
4. If the problem is corrected, replace the blower relay.

Scheme 24

Scheme 25

Scheme 26

1. Measure terminal-to-terminal resistance of the blower resistor.
2. If measured resistance is not within specification, the blower resistor must be replaced. (After removing the resistor)

Scheme 27

1. Disconnect the negative (-) battery terminal.
2. Disconnect the blower resistor connector (A) at the connecting part blower unit.
3. Remove the blower resistor after loosening the mounting screws.
4. Installation is the reverse order of removal.
