The drivers door takes three or four blips to unlock (all other doors fine).
Had the door card off and gave it a good spray with WD40 and silicone spray and cleared a bit of the sound material from around the button area etc. but to no avail. So is this a mechanism replacement or could it be a supply/ECU (Engine Control Unit) issue? If it's a replacement is this doable with just the door card off as a one man job?
