How to fix dampers of air conditioner on suzuki grand vitara I only get hot air seems that the damper does not move
To fix air conditioner dampers on a Suzuki Grand Vitara that only blows hot air, follow these steps:
1. Check for DTCs (Diagnostic Trouble Codes):
- Connect a scan tool to the DLC (Data Link Connector) with the ignition off.
- Turn the ignition on and check for DTCs, specifically DTC B1512.
2. Check Mode Selector Operation:
- Start the A/C system.
- Turn the mode selector to "DEF" and then to "FOOT" position.
- Wait 1 minute and recheck for DTCs.
3. Inspect Actuator Linkage:
- Check for any obstructions in the actuator linkage.
- Ensure the actuator linkage moves smoothly.
4. Check Wiring to Actuator:
- With the ignition off, disconnect the connector from the air flow control actuator.
- Inspect the wiring, especially the GRY/RED and GRY/BLK terminals, for proper connection.
If there are faults or obstructions in the actuator or wiring, repair or replace the faulty components. This should restore proper damper function and allow cold air to flow.
