Honda Car Forum

I have a 2008 Honda civic which has a poor radio reception when the rear defroster is turned on. From previous post I noted this is probably because of a bad grounding of antenna or defroster. Can anyone tell me where to find these grounding points? Thanks!

your problem may be related to a bad noise reduction condenser. there is one located behind the trim on the left "C" pillar. that condensor is similar in function to the old condensors in the distributors with breaker points that were used to absorb electrical interference from the ignition system.































you will have to check with a Honda dealer to see if the "Noise Reduction Condenser" is available separately or if it is a part of the harness. as for the location, it should be to the top of the C Pillar above the point where the defroster grid connector is. it has a two pin white connector but the condensor is probably shrink wrapped around the harness.































the ground is also behind the C pillar trim.































by the way, the car should be under warranty if you have less than 36,000 miles in the U.S. not sure what the warranties are elsewhere but the warranty applies to the car, not to the owner so even if purchased used the car may be under warranty. I'd check first before you go taking things apart because if it is under warranty the repairs will be at no cost to you.































hope that helps
