We have a 323 1.8 executive '97 with a very stange problem with the radio.
Quite often if the radio is on, when the car is turned off the radio remains on and the only way to stop it is by removing the fuse.
Other times the radio won't come on when the car starts, then will suddenly come on after about 15 minutes.

The radio itself has been checked out, and the ignition switch and wiring.
It has been suggested it may be a sticky auxilliary relay. I was going to replace this - but I don't know where to find this?

I was wondering if anybody had experienced any similar problems or knows where I might find this relay ?

Thanks very much,
