AC blowing cold but not ice cold?

[texasaggies16]

So I dont think my AC condenser is completely ruined? BUT I found it odd yesterday after a 1 hour drive of having my AC on LO and max blowing the truck just never felt COLD, it felt cool and comfortable but it never froze me like I feel like it use to be able to..

 

Could my system just be low on freon or something?

If it is low on a charge it means it has a leak, its a sealed system. Drop a thermometer in one of the vents and keep the rpm at 2k and see what it does.

Mine is the same, never gets freezing cold. 

Whats the temp it should be at proper working levels anyone know? I will measure mine as well.

Likely not low but has picked up moisture. Id start by recovering the charge pulling a vac and recharging tonfactory spec.

In Huston yesterday? Recycle closed? Windows solar tinted? You mean lowest percentage of cooling or lowest cooling setting? This a four door pickup? (large cabin).  Deck stacked against you? 

 

Close the air recirculation and drop the fan speed to 50% with the AC set to the coldest setting. Open the windows a few minutes to rid the cabin of the 'hot soak'. Give it a chance.

I thought mine was the same. Had to be a leak. Looked everywhere and did a test. No leak. Had it recharged and it was worse. Buddy that did the work, because I don't have the tools for ac. Said leave it on max with the seats on ac max also and let it cycle. So I did. Gets so cool in there my balls hurt, I love basketball shorts.
So it seems there is some type of black magic in there. I asked buddy wtf was that why. He said something about the transfer from a liquid state to a gas. So yes black magic gypsy stuff.
Hope that helps.[emoji38]

Yes Houston, heat index of 110 degrees.

5% tint on all windows, crew cab. 

 

Something doesn't feel right as even this morning with a temp of 80 degrees I couldn’t get the truck to freeze me out.

Recycle? Fan %? Length of time you expect it to turn you into ice-cream? Have you dropped a thermometer in the vent yet and measured the air temperature? Might be instructive to see how reality (actual vent temperature) and your expectations line up, eh? 

 

Take note of 1SLOW1500's comment of fan speed vs vent temp. His guy is on the money.

Let me know what yours measures out regardless!

Gave in and went ahead and dropped off @ dealer...

I dropped the truck off at the dealer about an hour ago, normally I would troubleshoot myself but with the heat coming up I just cant take a chance.

 

Yall pray for me and my wallet. Will update when they call me.

I'd wash out the condenser too. Just did mine the other day, removed the fan assembly and went to town with a hose on the back side of the radiator and condenser to flush out all the dirt clogging the fins.

 leaking condenser; 15 Sierra 75k miles. dealer wanted $1,500 to fix it. Told them to kick rocks. They called me back 5 minutes later and said $252. Not happy about the situation but to not lift a finger to mess with it sure is nice.

 

dont let these stealerships bully you, I had to get really loud on the first call ha.

Haha wow, 1500 to 252.. thats a quite discount. I wonder why they went that low.

[Ed S]

On a 95 degree day my vents measure about 60 degrees. Not that cold but never has been and freon is completely full. That is when my actuators are working properly. Seem to have to keep recalibrating the one for drivers side vents. For over 50k new these truck are pretty weak built and designed.

My service advisor said they adjusted labor codes? I got a brand new condenser and it all fixed in under 2 hours. Im sure i got some kind of "GM assistance", but I honestly didnt question that number LOL.

Agreed, I knew this problem existed but didnt think id get unlucky and it happen to me.. sure is frustrating when your just about to have it paid off.. I know this might influence my next purchase later down the road.

well really hot days 103 like we have had recently in texas. at idle about 55 degrees out of vent, driving down the road should be 45-50ish.
