Symptoms

Root Cause
Water ingress from the scuttle panel drips onto the blower motor, increasing resistance. This burns out the thermal fuse on the heater resistor pack.
How To Fix
Replace the heater resistor pack (located behind the glovebox, £20 part). Check the pollen filter is dry and clear scuttle drains. Cost: £20-50 DIY.

Other Faults on This Variant
Coolant Loss and Head Gasket Failure
SevereThe Z12XE and Z12XEP 1.2-litre petrol engine in the Corsa D is known for coolant loss. In many cases this escalates to head gasket failure if not caught early.
Oil Pressure Switch Leak
ModerateThe oil pressure switch frequently fails internally, leaking engine oil directly into the electrical wiring loom.
Timing Chain Tensioner Rattle
ModerateThe Z12XEP 1.2-litre engine develops a timing chain rattle on cold starts. The hydraulic tensioner weakens with age and the chain slaps until oil pressure builds — a warning sign that should not be ignored.
