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.
The PCM controls the compressor clutch based on inputs to PCM and ACP. When all inputs to PCM and ACP are within acceptable values, ACP signals the PCM to engage the compressor clutch. Once the A/C clutch is engaged, minimum compressor clutch on time is determined by either of following modes.
