2005 Volvo S40 1.8SE - Nearside doors will not unlock - extaf

Hi folks,

my Volvo central locking has been a bit iffy on occasions but now neither of the neaarside doors will unlock and I can't use that side of the car. In the past such faults have fixed themselves and I have then been able to clean the terminals. But now, I can't get the doors open to fiddle with the terminal block. Any suggestions please?

Thanks Extaf
