AC Cycling

[Sajan]

It's mid 80s F outside, I have the AC on auto at 74 F.

I noticed the AC cycles very frequently.
It goes from cold air to lukewarm air ...a lot. I can hear it come off and on ..like every 30 secs.
Is this normal for these trucks? Are there any diagnostics I can perform using techstream?

I had something like this in my 5 series back in 2020 and they ended up replacing the AC compressor under warranty I think

Not normal for my ‘17. How’s your refrigerant charge?

I had the same recently. Was the ac compressor. Or as I like to call it the “ac compre$$or” lol

My shop looked at the relay and switch, refrigerant charge, ac pulley, then compressor. Found metal bits on the outside (not inside). Iirc if there’s metal bits “inside” the fix is much more involved/expensive.
