Power door locks fail with use of keyless remote entry. When testing circuit amperage draw finds a 19 amp electrical spike on a 20 amp circuit. Suspect this to be to high for circuit protection. Fuse blows frequently. When doors are locked headlights and tail lights will flash momentarily which is normal. The circuit load is to high for a twenty amp fuse. Suggest GM to increase circuit protection amperage or decrease amperage draw. Dealer unable to locate problem.
