Poor A/C Performance During Acceleration
(Supersedes 07-062, dated January 30, 2009, to update the information marked by asterisks)

*REVISION SUMMARY

Under WARRANTY CLAIM INFORMATION, the flat rate time was changed because the MVCI updates control modules more efficiently.*

SYMPTOM

The A/C cools poorly during hard acceleration under 20 mph. This symptom is usually noticed in stop-and-go traffic.

PROBABLE CAUSE

When accelerating at speeds below 20 mph with the accelerator pedal more than halfway down, the ECM/ PCM turns off the A/C compressor.

CORRECTIVE ACTION

Update the PGM-FI software with the HDS.

NOTE:
The software update minimizes the symptom, but it does not completely eliminate it. The customer can improve A/C performance by accelerating from speeds below 20 mph with the accelerator pedal less than halfway down.
