Title: Severe radio interference when heated window switched on
Post by: Darius on 08 December 2018, 14:36:51

My radio is normally fine - I listen to FM.

When I switch on the heated rear window I can no longer hear the radio because of all the interference.  I searched the forum for ideas and I have checked the connections to the heated rear window and they seem fine.  There are no breaks that I can see when I heat a misty window - all the horizontal elements heat up.  Were it a petrol car I would suspect suppression as being the problem but it is a diesel.  The interference doesn't seem to be related to engine revs.

Any ideas where I should look?  It's a 51 reg.

Assuming saloon, due to symptoms....

It will likely be the 0v connections to the bodywork. Check both HRW and the aerial amp 0v (earth) to bodywork

Thanks.  It is a saloon.  I'll have a look at the 0V (earth) connections and let you know the results.

I had the same on my last saloon, gave up drilled holes in roof and fitted a bee sting.

I was thinking about using a coat hanger but so many are plastic these days.
