Air Conditioner problems of the 2004 Volvo S60

2004 Volvo S60 2. 5t. Purchased the car used in sept 07. 6-5-08 panel displayed open rear door while driving 65mph on highway, my door was not opened. Car jerked as if there was power loss, ac went off, brake failure light on panel, power windows and locks did not work, temp 105 , then driver panel went black. Car jerked 3 times in mid traffic, I was scared to death for my life. Arrived at my exit, pulled over to a gas station, engine still running but sluggish, radio was still on, power door locks and windows did not work, ac off. Engine still running so I made it a couple of miles up the street to my home. Cut the car off and back on, all power returned, now check engine and air bag trouble on panel. Went to Volvo dealer next day 6-6-08 near my home, they can not see my car til next week Tuesday. Went to pepboys, battery and alternator are ok, can not access engine box, must go to dealer. Called Volvo for Tuesday 6-10-08 appointment. Car duplicated same problem Monday 6-9-08 on drive home from work on the highway temp 105 etc. Searched for complaints and recalls, my recalls were reported completed when I purchased the car, found all of this valuable info online, will see dealer tomorrow and take these related copies of complaints with me.
