Intermittant A/C operation.

[Rhino]

I did notice the buzzing pretty regularly when I first purchased the truck. It seems to have been less frequent as of late. Not sure if that's a good or bad thing. I just recently found out what it was by accident. I had completely forgotten about it until now. I may replace it just to be on the safe side.



With that said, it looks like I spoke too soon in regards to the steady temp in manual mode.
It does still seem intermittent. I did notice that under even very moderate acceleration (pulling away from a stoplight) it does warm a considerable amount. I believe the compressor clutch is PCM controlled if I recall correctly. When tuning the truck I can't see any possible reason why I would have messed with the enable TPS position, but it is a possibility. Tomorrow I'll hopefully be able to pull the tune back down and do a log for confirmation.

Barring any tune issues, is there any reason the system would warm up on acceleration?
