What causes Car AC Stopped Working?
These are the faults we most often find behind this symptom on cars driven in Hyderabad's heat and stop-go traffic:
- Blown AC fuse or relay — AC circuit gets no power
- AC compressor completely seized — compressor clutch locked
- AC pressure switch fault — system cuts off due to incorrect pressure reading
- Blower motor failure — no airflow even if AC is cooling
- Complete refrigerant loss — system has no gas to operate

Frequently asked questions
My car AC suddenly stopped working in Hyderabad summer — what happened?
Sudden total AC failure is usually an electrical issue: blown fuse, dead relay, or seized compressor clutch. Check the AC fuse in the fuse box first (your owner's manual shows location). If the fuse is fine, the compressor clutch may have seized — you'll hear no compressor engagement when you switch AC on. Metre Per Second diagnoses all AC electrical and mechanical failures same-day.
