Renault Repair Questions? Ask a Mechanic for Answers ASAP
Hello and Welcome to justanswer...
This could very well have caused such an issue / problem yes..
Water / rain can get into the fuse boxes on these models and cause different electrical problems / issues - or, it can get into the actual door panels and do the same.
It will be a case of accessing your fuse boxes and insoecting them very carefully for signs of water ingress - (and of course check the relavant fuses to see if they have blown - or just bad connections.. )
Obviously you need to deal with what you find...but if there is no such issues - then its going to be either remove the door panels ( inners ) to gain access to the inside to check for water ingress -and again deal with as you find or have a plug in diagnostic test done at a Renault garage or other, that has suitabel plug in equipment ( that plus on the vehilces obd diagnostic socket ) to trace the fault down..
This will find the fault/s whether its on one particualr lock / mechanism or on the control side / computer module side....
Its then a case of which way you want to approah it - its not easy to get the inner door panel off when the door wont open - but if it comes to that, one tip is to remove the rear banch seat first ..that gives you more access..
So those are the different causes & ways forward for you on this one to get it sorted out - - Im sorry there is not one-shot / easy solution - but I have given you the different ways that wil help you get to the bottom of this one for you...
