(Based on previous questions)
Background: I've been having trouble with the AC in my '04 Corolla. The compressor was replaced and subsequently the shop reported bad fuse contacts which they addressed. However, the AC didn't cool in a significant, consistent way even after the fuse issue was addressed.
My next step was to get a second opinion from another mechanic, I'll call him Mechanic #2. He asked me to open my glove box and pull out the AC filter to look at it. It was filthy. Since I will need to replace it anyway, I didn't bother putting it back in.
I feel as though the system has been performing markedly better since I pulled out the filter. Is this just my imagination? Or can pulling a dirty filter out make a significant difference in the cooling effects of the AC system?
Also -- is the filter something I can pick up at an auto parts store?
(Note, I'm not asking whether this is the whole solution to the problem -- obviously there's no way anyone could answer that!)
