When accelerating or climbing a hill, the climate control of my '93 960 changes from the dash vents to the floor vents until the vacuum rebuilds. I have searched and searched for a vacuum leak. Both black/white vacuum check valves on the firewall have been replaced. The cruise control works perfectly so that portion of the system is fine. The brake booster check valves is fine. The brakes do pulse a little, maybe the vacuum leak, maybe warped rotors. This was always a cinch to fix on the 740's. Does anyone have experience correcting this symptom on the 960? Thanks.
