Should I be worried about a burning smell from my Suzuki Swifts AC o r vents?

Occasionally, I notice a burning o r plastic-like smell coming from the air conditioning vents in my Suzuki Swift, especially when the AC has been on for a while in hot weather. This usually happens during peak summers in Pakistan. Could this be due to wiring issues, a clogged cabin filter, o r something more dangerous like an electrical short? Is it safe to continue using the car without getting it checked?

Yes, a burning smell from the AC o r vents can be a sign of an electrical issue and should not be ignored. It could indicate melting wires, a failing AC blower motor, o r debris caught in the ventilation system—any of which could be a fire risk if left unattended.

Common Causes in Pakistan:

Dust o r leaves trapped in the AC blower motor, especially in dusty areas.

Overloaded o r failing AC motor, drawing too much current.

Short-circuited wires o r connectors, especially in older models o r those with aftermarket accessories.

Clogged cabin air filter, overheating the system.

What to Do:

Immediately stop using the AC if the smell persists o r intensifies.

Get the blower motor and wiring inspected by a qualified technician.

Clean o r replace the cabin air filter regularly every 15,000–20,000 km.

Avoid using cheap electrical accessories that overload the system.

Ignoring the issue could result in electrical failure—or in rare cases, cabin fires.
