Sorry if this has been asked in the past, but the a/c and recirculate lights blink once in awhile when starting the 850 wagon. When this happens, the heater motor will not run. I spoke with the Volvo dealer and he leads me to believe it is the resistor pack connecting to the heater motor. My intuition tells me it is the heater motor that needs replacement. A shutdown and restart of the car eliminates the problem. One more thing, this problem occurs most often, (but not always) in hot weather.
Has anyone ever encountered a bad resistor pack in an 850? And where is the resistor pack located?
