AC question

[jsbihn]

Ok so I just picked up my truck from getting the AC fixed. Here is the run down
New compressor
New Dryer
New tube
new freon
New Belts
ac was flushed

I get in the truck and turn it on, and it blows cool
not cold... cool

So I am thinking it might be the air from the outside but it is a little cooler then that.
Then I drive it a little, it gets colder... but definitely not like it did before the compressor went out.

Ok, now I drive it around 50 for a few minutes and it starts to get colder. Definitely is working but it seems that ever time I slow down or something the AC doesnt blow fridgid like it did prior to the compressor going out.

I am wondering if there could be an air bubble in the system
does that stop it from cooling
Or could there be a leak or something?

Given it was night time out when I tested this and tomorrow I am driving it in the heat
I am just wondering what you guys might think is going on

Doesn't it have something to do with the fact that the Hummer runs an engine mounted fan instead of electric fans? Basically what happens is when you slow down or stop, the rate of airflow through the a/c system slows, so it doesn't cool as much.

I notice with mine that when I stop, the system wars up a little, but once I get moving it cools back down.

It will fluctuate a little due to the mechanical fan, as VM stated.

Grab a temp gun and see how cold, or warm, the air coming out is. I forget what a car A/C is supposed to be but Google can tell you real quick.

I noticed on mine sometimes it does the same thing and if I turn the temp all the way hot and then all the way cold it will get much colder. I thought the blend door was sticking but it will do it on both sides so maybe it needs to be calibrated or something.

I guess what I am really asking is why isnt it as cold as it was before the breakdown?

I mean is there something that could have been done or not done that is causing the AC not to be as cold as it used to be?

OK, here is the latest
- Today ... driving into work I noticed the AC cycles.
After driving for a long time, I noticed that the entire time it went from cold to cool and back to cold again...

Basically it will blow ice cold air , and then it will blow cool air.... then cycles again. You can actually feel and notice the temp change

I dont remember it doing that before the compressor broke.
So what do you think is going on ?
I would really appreciate any answers because I want to be able to take it back with knowledge so I dont get the "oh its suppose to do that" response
