Check the below: Found it while browsing various Chevrolet websites to find out any info I could about my new 2013 Sparl 2LT. Hope this helps.
On some 2013 Sparks, the air conditioning may only blow warm air or may get slightly cooler during acceleration. During diagnosis, the A/C pressures may be erratic and the low side may be as low as 0 psi to 30 inches of vacuum.
Inspect for metal contamination in the A/C system by removing the plug from the bottom of the receiver/drier and checking for debris in the filter assembly. Also check for debris or contamination in the thermal expansion valve (TXV). If contamination is found, perform repairs as outlined in the appropriate Service Information and verify repairs.
