Questions and answers
Adjust throttle motor
The idle speed on a Suzuki SX4 should be controlled by the Idle Air Control Valve (IACV) rather than adjusting the idle screw on the throttle body, as the screw is factory set. Before using compressed air in the idle-air-bypass passages, the IACV should be removed to prevent damage to its delicate mechanism. If there is an issue with idle speed, checking the IACV function and referring to the SX4 service manual is recommended.

Possible issues with the heater in a Suzuki SX4 if the blower is working but the heater is not include:
1. Incorrect Temperature Output
- Temperature control cable broken or bent (non-A/C and manual A/C) → Check the temperature control cable.
- Temperature selector faulty (non-A/C and manual A/C) → Check the temperature selector.
- Incorrect installation of the temperature control cable (non-A/C and manual A/C) → Check and adjust the position as necessary.
- Temperature control door assembly broken → Repair the temperature control door assembly.
- Air ducts clogged → Repair air ducts.
- Heater core leaked or clogged → Replace the heater core.
- Heater hoses leaked or clogged → Replace heater hoses.
- Thermostat faulty → Check the thermostat.
- Temperature control actuator faulty (auto A/C) → Check the temperature control actuator.
- HVAC control module faulty (auto A/C) → Check the HVAC control module.
- Wiring or grounding faulty (auto A/C) → Repair as necessary.
2. Other Possible Causes
- Air flow control cable broken or bent → Check the air flow control cable.
Checking and addressing these components should help identify and resolve the heater issue.

دلایل بالا رفتن مصرف بنزین در مدل اتومات
increasing revs when changing gears
The Suzuki SX4 may have increasing revs when changing gears due to its drive-by-wire system and the difference in final drive ratios between the manual (4.41) and automatic (2.81) transmissions. This difference causes high cruising RPMs in the manual version and sluggishness in the automatic. Additionally, if the revs climb while going uphill, it may be due to the transmission downshifting or kicking out of overdrive. Other possible causes include low transmission fluid, abuse, or a faulty transmission design.
