The check engine light is on all the time. I have replaced the gas cap, changed spark plugs, changed some hoses, fill coolant. The airconditioner/heater does not blow air out the drivers side vents. It has a loud knocking noise that I hear inside the passenger cabin. It kind of smells like something is burning after I filled the coolant.

Check engine light On

Go to Autozone its a free public service and have the computer scanned for code/s-you have a problem within the engine management system that caused the CEL to turn on-This is your starting point of diagnosis,finding out what's going on

I went to Auto Zone and got a diagnosis or code P1110 and P0455. However it wasn't for a 2000 Saab. The salesman suggested I go home and google the code. So here I am trying to figure this out. Meanwhile the car was supposed to have had a new radiator installed. I don't think that happened because I have had to add coolant twice within 3 days. Why did I agree to have this car? If anyone can help or give me advice it would be very much appreciated.
