If one or more of the above problems are identified on this vehicle model, this may be associated with corrosion of the multi-function relay.
One possible reason for this may water ingress in the left tail lamp. In this case, the relay installed under the lamp should be examined and replaced if necessary.
Then check the sealing surfaces of the tail lamp and enhance the seal if required.
