No crank 528

[jetfixer]

My 1998 528 will not crank. My wife who normally drives the car says this has been an intermitant problem the past few days, she just persists and the car will eventually start. Till now, just no crank. It has a good new bat. with good volts. All acc. and electronics work fine radio etc.
I am told this could be a door relay or other relay. Where are these suspect relays.

Thanks in advance
