Just had the compressor changed. Does anyone know if this much frost is normal on the accumulator?

I don't know but it looks like it is working good to me, must be nice and frosty inside?

Best to take it back to the shop and make sure they notate the discharge and suction side pressures on your ppwk. It will be your fault if something isn’t corrected now or documented there were issues. Buy a cheap digital thermometer to stick in the dash vents to cya too

Got my truck back today after having one of the upstream O2 sensors replaced.

Played with the AC and still wasn't as cold as it used to be so I went and got a can of freon with the gauge. It took just a little of it. Just a little colder.

I started playing with the climate control and noticed that if I would raise the temperature from 60 to 70 there was no change in the temperature. I then raised it to 80. No change all cold air. So I kept playing and playing and there seems to be a issue with temperature change. I would leave it on 75 with cold air still blowing out and then ten minutes later it would change to what felt like 75. If I changed the temperature radically and felt no change I would play with the position settings and it would eventually change the temperature to what I felt like the proper temperature would be.

Anyone know if this is a climate control head unit issue or a actuator issue? Tried the sparky's actuator reset with the fuse but no change.

You may have climate control issues. Your accumulator may freeze lightly if the blower is not on high. Fix your climate control and the test your a/c.

Probably an actuator but you need one of those tools we talked about in the other thread to know for sure and not be throwing money at it.

Press your shop on this. If they changed the comp and it’s still not working, take it back until it’s fixed. If they can’t fix it then you should not pay to have them swap new parts in that we’re not needed.

Work with them, but be persistent, the goal is to get the a/c working. They may have to eat the rest of the cost to fix the rest of it. If they won’t or can’t fix it call your credit card company and request a chargeback for failure to perform services paid for.

Accumulators can be/become clogged.

It is basically a particle filter. When the accumulators are not wrapped in rubber or foam, condensate and contaminants can clog the flow of cold air.

Those contaminants mixed with water make hydrochloric acids, and create internal corrosion. The blockages stop/slow the cooling process.
A tell tale sign is :
1) No cold air
2) Significant reduction in cold air
3) Rattling from the corroded parts
