W140. Rear demister problem & Radio

[marklaxton]

Thanks for your help dieselman.

The rear demister on my S320 does not work. I have checked the fuse and this is OK. I heard that Merc use the rear demister as an aerial for the radio . My radio does not hold a strong signal which would lead me to believe the connection to the rear demister is somehow broken. Anyone any advice pleae ?

You need to remove the trim on the nearside C pillar to access the two spades that connect to the screen to see if you have 12 volts on it.

It is a common fault that the window causes cracking on the radio

The only cure is to replace the screen if it is open circuit
