The ECM in a Chevy Spark keeps an eye on the A/C compressor relay control circuit. If the control circuit gets grounded, the ECM will trigger code 68, and the A/C compressor won't work. Common reasons for this issue include wiring shorts to the A/C compressor relay and a faulty relay itself. The A/C compressor relay is vital for powering the compressor and clutch. If this relay malfunctions, the compressor won't receive power, making the A/C system unable to work correctly. A failing relay can lead to sporadic power supply to the compressor, causing inconsistent cold air production in the A/C system.
The Chevy Spark error code 68 indicates a malfunction where the pump motor is not operating as it should.
In fact, code 68 pertains to a stabilizer track system. Avoid searching online for information on stabilizer track systems using these codes. Refer to your manual for the accurate definition of each code. If you're unable to find the information you need, contact the certified technicians at John Hall's garage for assistance.
