Does anyone know what is causing my A/C to not blow really cold air during the day? At night it seems to be fine, is this normal? The a/c coolant levels are normal.

Also why is it that when I have the A/C on, it sucks up a lot of the bad smell and goes straight into my cabin? For example, if I were to drive behind an old truck or suv, I can smell all the smoke that's coming out of it. I have replaced the cabin air filter many times and I still get the same problem. Is it because I'm not using OEM cabin filter?

And is there any way to fix a clogged windshield water nozzle? It's only clogged on the driver side. I tried sticking a safety pin in the hole but it didn't do anything to help.

 

the cabin filter is designed to filter particulate matter down to only a certain size. so you probably won't get the soot from that old truck, but u can still smell it.

dunno about your ac, who checked the refrigerant pressure?
