Poor radio reception

I noticed that switching on rear window heating causes interference, so that C18 probably needs to be replaced. Is it near the amp? What is the part number? Thanks

Not sure around the window trim somewhere, there may be two.
Check the earths on the rear screen as it sounds like one is bad and so it's earthing through the supressor and when you turn the screen on there is too much resistance for such current.

Hi snapdragon, thank you for your advice. I removed the trim above the window again. I only found one earth wire there, and it appeared to be OK. However, I tried if removing makes any difference to the radio when the rear window heater is on - it didn't. I couldn't see the suppressor(s) - I found a picture and I think I know how it looks like.

I'm still thinking is that amp working at all... one would think that removing the earth cable would make some difference to the radio.

Finally had a chance to look into this again. I was able to bend the top of the side trims around the rear window - couldn't see any earths there so I guess they must be near the bottom edge. To get access there means removing the parcel shelf... which I guess means removing the rear seats first?

Can anyone definitively confirm that the earths are close to the bottom edge of the window?

Thanks

Frosty morning today revealed that top 4 lines (area where the antennas are) do not warm up when rear window heater is on. Should they? Also left/passenger side section of 6th line from the bottom edge is dead.

I set my alarm to check mine in the morning.
Will try and get a photo.
