you might want check the air filter, their was a message about snow that becomes packed into the air cleaner. if this has happend it could have damaged the filter. they make a deflector to install in the housing, and if you plow snow you should use a winter grill. this will prevent it from happening again.
ive got the compressor clunk when it engages, and have read into it some but not much talk about it other than the tsb.
my question is this hard on the truck to not fix, is it just the sound that is the problem or will it take out the tensioner or compressor if let be?
I don't think that it will hurt the drive belt, tensioner or compressor. I have not seen many a/c system failures. I think it's the freon flow through the accumulator when the compressor engages. Not sure on that though.
