Question about 1998 Volvo S70
This all happened within a couple of miles of driving home. First the air conditioner stopped blowing cold air. Then the battery light came on. Then there was some white smoke. Then the idling was high as I waited at a light. The final half mile home, the engine was jerky and the speedometer was stuck on 55 mph no matter what the actual speed, and the RPM was stuck on 3 (30,000?) no matter what speed.
You need to look under the hood, located the Broken/Missing Serpentine Belt. Repair the damage the belt did when it broke and put a new one in. The Alternator is not turning and that is causing No Power to get to the systems and more than likely, when it broke, it knocked some wires around.

SOURCE: High idle at starting
Sounds like you have a vacuum leak in the air intake side. Check all your small and large hoses around the throttle body. Also check your idle air valve....cylindrical device connected to the the air box at the front of the engine.

when you day the air goes on and off i assume you mean the compressor goes on and off. that is what moves th freon through the system. if you are getting cold air when the compressor is running then the problem is that the compressor is stopping and that would be because a pressure switch may be bad. it is possible that model has a thermal shut down too say if the compressor was low on lubricant and was overheating when it does run. but if it is a pressure switch that is failing and they do, it is an easy fix. if you follow the ac lines you will find the switch.it is small about the size of a sparkplug-attached to the ac line and will have a connector with two wires. if the car is running and ac is on but the compressor is not turning remove the connector and jump to two wires. the compressor will start running if the switch was bad and we are sure there is a good charge on the system. if you are getting cold air there should be a sufficient charge to close the switch. these switches can be removed without losing any freon. there is a valve below them that will shut off when the switch is removed. then all you have to do is get a new one and screw it into place,apply the connector and you are done. if that is the problem. hope this helps please let me know and good luck
