What to Do When Car Air Conditioning Buttons Don't Respond?
2 Answers
If the pressure is too low, it indicates a lack of refrigerant, which needs to be replenished. Insufficient refrigerant will affect the cooling performance of the air conditioning system. Check whether the blower of the air conditioning system is operating normally. If the blower malfunctions, it may result in no cold air coming out of the vents.
Last time I drove, the AC button didn't respond and I almost got heatstroke. Actually, this is quite common. Start by checking the simple things: open the hood, locate the AC fuse in the fuse box, pull it out and see if it's burnt black. If so, try replacing it with a new one. Then check if the AC button itself is stuck or has dust in it—use your fingernail or a small stick to gently pry it. If it still doesn't work, check if the battery terminals are loose or oxidized, clean them, and try again. Finally, after starting the engine, listen for any sound from the compressor. If there's no sound, the control module might be faulty. These small checks can be done by the roadside. If none of these steps improve the situation, take your car to a repair shop immediately—don't push through, as heatstroke or compromised driving safety could be serious. Remember to lubricate the buttons during regular maintenance to prevent issues.
