EClass Windows horn and indicators playing up!

[gazzab]

I had a problem a few months ago when the key got stuck in the ignition on my wifes 2001 E320CDI. The guys on here diagnosed the problem and the car was fixed. Now I have a problem that has showed itself now and again (and before the key got stuck) but I wonder if it might relate to the key / ignition electrics....?
Now and again the windows wont operate, nor will the indicators or the horn.
The hazards work as do the lights and engine ! I THINK the aircon stops working as well. It will come back to life after 10 mins or if you turn the ignition off and back on again.

Anyone any ideas ?

thanks

Gary

Hello again, this must be a poor contact in one of the relay units in the front fuse boxes

Turn the indicators on while tapping the relays and fuses
