Sounds like a load of BS, but I took my car to a dealer the other day for a AC recharge and they told me that it was blowing warm because the AC condensor has a blockage... I think its crap beacuse he told me that one line is hot and the other line is cold, does this sound right or like crap? It blows cool air and its all good ever since the recharge

 

If its all good and still blows cold then id say screw it.. when it stops getting cold though id go back and check it out..

 

Ya, they said something like it doesnt flow properly at higher rpm etc... sounds like they were just trying to sell a job.
