My cultus 2007 non efi: AC throw is low although ac is chill. My AC was working fine with low throw suddenly burning smell of rubber type thing started to come from AC and i kept running for 5minutes more. Suddenly smoke(steam) as if somethng has gone extremely hot, comes out of vent. I immediately switched ofF ac. However, i felt air was still chill. Pls help me solve this, what can be the issue
