I'm Awesome
I feel like I need to start this by saying the only knowledge I have on A/C systems is from what I've figured out along the way of fixing issues on my vehicles. I'm going to try to put as much info here that I can about this issue. Also, to preface this story, the A/C blew ice cold before the blend door replacement, just not through any single vent location very good.
2000 K2500 standard cab, 7.4. The issue is that after I pulled the dash and replaced all 3 HVAC doors, evap core, and heater core, My AC doesn't blow cold after recharging it to 2.0lbs using a Robinaire machine that my dad has. it blows cool, but not cold. Thermometer said 60 degrees. I had to replace the liquid line and condenser due to me stripping the threads on the originals trying to put them back together. Ignorantly, I didn't get a new orifice tube for the old condenser because I didn't notice the old condenser having one so I wasn't sure that's where it even went.
This is the condenser I bought from RockAuto. I see in the info, it says to replace the orifice tube if it isn't integrated. Would this definitely say if it was integrated? it doesn't say either way so I'm really hoping that it is integrated and I have another issue.
I did verify the compressor is kicking on when I have the AC button pressed (also while I have the temp knob on max cold). The button lights up. I pulled vacuum with the machine and let it sit for 10 minutes and I didn't see any leaks. The line from the compressor to the receiver drier is ICE cold, but the connection coming off of the receiver drier going to the evap core is room temp.
I guess my questions are:
1. Any way to know if that condenser I bought/installed has an integrated orifice tube without taking it back apart?
2. If it doesn't have an integrated orifice tube, would having one not installed make the AC blow warm? I will buy and install one if it needs one (if it's not integrated into the condenser), but I need to get to the bottom of this issue regardless.
3. If not having an orifice tube wouldn't make it blow warm, any ideas what else to check next? I'm kind of at a loss since the system has a charge of 2lbs and the compressor is kicking on. Maybe the receiver drier is clogged since it's connection with the evap core is warm?
