Professional Mechanic Tips

Field notes from Marcus Vale, ASE-Certified Master Technician
Wiring that flexes in the door hinge boot can fray; wiggle-test it if the light flickers over bumps.
On a Porsche 718 Boxster the door light that will not clear is nearly always a worn jamb switch in the latch — spray it clean first, replace if needed.
