This heat is brutal, and I'm pretty sure my car's AC is on its last legs. It runs, but it barely keeps the cabin cool anymore, especially when I'm stuck in traffic. I'm trying to figure out if it's something simple like a recharge or a bigger issue. I've been reading up on the signs of weak cabin cooling to see if my symptoms match up, like weak airflow or warm air from the vents. Before I take it to a shop and get hit with a huge bill, I want to be prepared. Has anyone dealt with this before? Is it usually the compressor or something else?
