The A/C in my 96 850 works fine (has had the evap & compressor previously replaced). BUT, I have a question on how often the A/C compressor should cycle on and off.

When I'm stopped in traffic or at a traffic light, the compressor runs continuously in 80+ degree weather. However, once I start moving and RPM's increase, the cycle times decrease. When on a highway in 80+ weather, the A/C is on 6 seconds, then off a couple seconds, then back on 6 seconds.

I should say that by the time I'm on the highway, my car is cold and the climate control has the fan very low. But is 6 second cycling too fast? What is the norm cycling time range for highway driving?

Thanks!
