Right then this is going to take some explaining so here goes.
The offside rear light warning symbol has been on the dash for a few months now but as all the lights worked i was not to bothered.
At the weekend the nearside warning lamp also failed and the left indicator bulb failed on the rear causing the indicators to go nuts as they do.
I waited a while and turned the ignition on again problem solved.
The problem with the crazy indicator has reappeared today so i went to change the bulb and discovered the block that connects the rear lamp cluster to the loom has a amelted terminal. All the plastic has melted around one of the holes.
Having discovered this i checked the offside to discover it has the same problem. when the connector block is wobbled the indicator on the rear fails.
Has anyone had this problem or know of any causes?
