SERVICE INFORMATION
EDITOR'S NOTE: This article replaces "Poor A/C Cooling on Hard Acceleration," from the October 2002 issue.
Does the A/C cool poorly during hard acceleration? You might be dealing with a normal characteristic of the vehicle.
To kick up acceleration and passing performance, the ECM/PCM cuts off the A/C compressor when you accelerate at or near wide-open throttle. Since it's a normal characteristic, there's really no point in replacing parts; you won't change a thing.

When to See a Mechanic
Stop DIY work and contact a certified mechanic immediately if any of the following apply:
- • You smell fuel, burning insulation, or see smoke.
- • Brakes feel soft, pull hard to one side, or make grinding noises.
- • The engine overheats, stalls repeatedly, or misfires under load.
- • You are missing required tools, torque specs, or safe lifting equipment.
- • You are not confident in the next step or safety outcome.
