What do you need to fix fan heater on peugeot 306?

To fix the fan heater on a Peugeot 306, you typically need a multimeter to diagnose electrical issues, basic hand tools (like screwdrivers and pliers) for disassembly, and possibly replacement parts such as fuses, relays, or the blower motor itself. Begin by checking the fuse and relay associated with the heater fan circuit. If those are intact, you may need to inspect the wiring and connections for any damage or corrosion. If the blower motor is faulty, replacing it would resolve the issue.
