Have any accessories been added to the ignition circuit? These may have pushed the current drain past the 15 amp fuse capacity. A multimeter across where the fuse fits can measure the current and give an idea of the drain caused by any accessories by switching them on and off. A heavier fuse may fix this condition. Otherwise there may be an intermittent short circuit somewhere that may be hard to trace and will likely still blow a heavier fuse.

Hello, I recently bought the car in online auction, they were using Vehicle Condition Report, so I could see the condition and I also noticed that I will need to make some updates, so there is my advice.
Based on the information you provided, it seems that your 2009 Volvo C30 is experiencing a recurrent issue of blowing fuse 26, which is related to the ignition switch. While I can offer some general advice, it's important to note that diagnosing electrical problems remotely can be challenging, and it's always recommended to consult with a qualified mechanic or auto electrician for an accurate assessment.

Blowing fuses can indicate an electrical short circuit or an overload in the circuit. Here are a few steps you can take to troubleshoot the issue:

Inspect the wiring: Check the wiring around the ignition switch for any signs of damage, such as exposed wires, frayed insulation, or loose connections. Pay attention to areas where the wiring may come into contact with metal surfaces or moving parts.

Check for aftermarket modifications: If any aftermarket accessories, such as audio systems or alarms, have been installed, ensure they are properly integrated and wired. Faulty installations or incompatible components can lead to electrical issues.

Test the ignition switch: The ignition switch itself could be faulty, causing the fuse to blow. A professional should perform a thorough inspection and, if necessary, test the ignition switch's functionality using specialized diagnostic equipment.
