Short post due to forum bug... Truck sits 3 or 4 days a week now, AC clutch makes harsh grinding noise when first engaging. Should I take it in to have it looked at or is this just because it's sitting?

My 5.9 does the same. Saw in another post someone mentioned it was because the compressor was at the lowest point in the A/C system.



Parts/Serviceis this a known issue?

 

I didn't see any know issues with the 2007. I did see a Tech tip from 2005 that says
"If the issue is a clunking noise when the compressor is first engaged on a 5.9L diesel engine, verify that the Powertrain Control Module (PCM) is at the latest software level."

Don't think that this applies to a 2007 but It cannot hurt to make sure the PCM is up to date...

 

Ok, thanks guys! I'll take 'er in for a lookie lou.

Any news on the "June Flash" everyone was talking about? I doubt it's out yet but thought I'd hijack my own thread.

I have not seen a June flash, but I have had a chance to hook up a truck to see.

 

Ok, thanks again!

Thanks David.

Mike, post up the dealer response if you take it in.
