96 k1500 A/C Short Cycle when cold

[imv8n]

Just bought this truck from a shop that said they replaced the A/C compressor. When I start the truck up the compressor will short cycle multiple times. After I drive it around I notice the short cycle will stop. I did check the Freon and its right in the middle of the green. Any suggestions on what else could cause this or is this normal?

depends on outside temperature, were you on a defrost mode when it happens

new compressor.. it may have original manufacture "debris". its usually a fluid challenging the freon.

 

I refilled two years in a row after a brand new one. runs excellent now.

full vacuum pull and refill. it gets expensive at a shop,

unless the shop knows it needs a flush for being new, they might let one in for free.

 

I knew to get the refill equipment on my own to DIY before it was put back together.
