Radio just buzzes shortly after dealer replaced engine.

[JStin]

A few of months ago my local Dodge dealer had to replace the block in the wife's 2000 Grand Caravan (at their expense) due to a botched attempt to fix an oil leak. I've since had to replace an after market remote starter (worked fine going in, never worked again coming out) and had an EGR code, while removing the EGR I found one of the wires leading to it had been severely smashed, after repairing the wire the code went away. Now the radio buzzes extremely loud, can barely hear any audio, seems worse in front right channel, no button pushing or mode changes affects buzz in any way. This is the Infinity radio, cassette, cd. Is this a known problem with this system or can I expect another smashed wire somewhere? I give the dealer credit for fessing up but I think they stood back and threw the new block in from a few feet away...

Thanks for any help!

There should be a choke, I believe mounted on or near the engine, which keeps the electrical noise out of your speakers. That could be your issue. Maybe it's not there anymore?

Jeff--Did it buzz immediately after the engine swap or did it just show up recently? At any rate I would go over the engine compartment and firewall with a finetooth comb. Look for any broken wires and loose ones, particularly ground wires and straps. If it was anything to do with the antenna, it would work OK with a cassette or CD. You might have to get under it to see in back of the engine. I would think if a choke was missing, it would have been noisey the day you got the car back. Good hunting.

another thing that could be the cause is the ignition wires that are used. Most wires generate a frequency that can be picked up by the radio, but most wires has RF suppression so that you won't hear the static sound associated w/ the ignition system. Try checking your ignition wires and make sure there are no shorts, hot spots, or cracks whatsoever.
