Fix power door locks that lock by themselves
locks cycle, Ford Focus, TSB 05-10-21
Ford has issued a technical service bulletin (TSB) 05-10-21 address problems where Ford Focus door locks lock by themselves on 2003-05 Ford Focus vehicles. Automatic door locking is a feature built-in to these vehicles. However, if moisture or corrosion builds up in the door latch electrical connectors, the system may see the door as unlocked and may continue trying to lock it. The TSB advises you to disconnect the door latch connections and clean them with electrical contact cleaners. Find those types of cleaners here. To prevent the problem from reoccurring, pack the door latch connectors with dielectric silicone grease available at any auto parts store.
