How to fix cigarette lighter in car?

If your car's cigarette lighter is not working, you can try the following steps to fix it:
Check the fuse: The first thing you should check is the fuse. Look in the owner's manual to find the fuse box location, and then find the cigarette lighter fuse. If the fuse is blown, replace it with a new one.
Check for debris: Sometimes debris or coins can get stuck in the cigarette lighter socket, preventing the lighter from working. Use a flashlight to check for any foreign objects inside the socket. If you find any debris, carefully remove it using pliers or a pair of tweezers.
Check the wiring: If the fuse and the socket are both okay, check the wiring. Look for any loose connections or broken wires. If you find any, repair or replace the wiring as necessary.
Check the lighter itself: If the fuse, socket, and wiring are all okay, the problem may be with the lighter itself. Try plugging the lighter into another vehicle's socket to see if it works. If it does, the problem is with your car's socket, and you may need to have it repaired or replaced. If the lighter doesn't work in another vehicle, it may be defective and need to be replaced.
If these steps don't solve the problem, it may be best to take your car to a professional mechanic or auto electrician to diagnose and fix the issue.
