Headlight Pod Failure
Symptoms
The pop-up headlights fail to raise, lower, or operate unevenly.
Cause
The 914's pop-up headlights are operated by vacuum actuators connected to the engine's intake manifold. Vacuum leaks in the hoses, failed check valves, or worn actuator diaphragms cause the system to malfunction.
Fix
Check all vacuum hoses for cracks and replace as needed.
Replace the check valve.
Rebuild or replace the vacuum actuators.
Complete headlight vacuum rebuild kits are available.
Cost: $100-$400.
