Minimum Compressor On Time

WARNING: This page is about a different car, the 1995 Cadillac Seville, 1995 Cadillac Eldorado, and 1995 Cadillac DeVille. However, it is still accessible from the selected car via links, so may be relevant.

When vehicle is operating at speeds greater than 20 MPH, minimum on time is limited to 2-6 seconds before the ACP will allow compressor clutch disengagement.

After minimum on time has expired, ACP will request PCM to disengage compressor clutch only if low-side temperature is less than 30°F (-1°C). When low-side temperature reaches 45-50°F (7-10°C), ACP cycles the compressor on again.
