Does anyone hear a thump or a thud when they are at idle. It kinda seems like it is coming from the passanger side firewall.

willwagner 12-28-2006, 11:13 PM Yeah, I noticed it last night. It has gotten cold here, and i had the defroster on and heard a thumping about every 30 or seconds, comming from the pas. side. I messed with things for a few minuets and found that when i turned OFF the defroster, the noise went away. Must be an air directing door of some type for the defroster. 68Nova 12-29-2006, 09:18 AM I get that noise as well when the heater is on. Mine has the ATC. My guess is that its the A/C compressor cutting in and out. Some compressors have a harsh engagement and I thinks thats what we are hearing. I could be wrong though........

Just another sound added to the list of seat popping and belt chirp. Now to get them all harmonized together... -Bryan gandgracing 12-30-2006, 12:20 PM Mine done same thing. Look at the a/c lines and they will be fozen up. I called the dealer about it and he said it was normal when defrost is being used. | ||
