You may notice a flashing AC light on your Volvo’s dashboard, but you’re not sure what it means. If this happens, you might have a faulty A/C unit. To fix it, first check the thermostat. If it’s set to a cold temperature, the A/C will begin blowing cold air. If it blows warm air, the problem could be the heater valve or the vacuum source.
Next, locate the relay and resistor inside the blower case. They’re located behind the glove box. The larger part of the cable should slide off the left-hand stop. To turn on the AC, push the A/C button in and release it for 5 seconds. The DTCs will appear sequentially and disappear when the ignition is turned off. If you’re not able to turn on the AC, you might have a faulty component or wiring.
Next, remove the black plastic faceplate that covers the climate control unit. This is a delicate part, so be careful. Use a putty knife with a blunt edge to lift it up. Then, remove the center section of the faceplate. This is located between the climate control unit and the switches. Afterwards, you should find the thermostat. It’s usually located near the switch.
