I bought this car about 2 months ago and it runs well. However, 2 days ago I tried the A/C to see how well it worked. Now I cannot get the heater to work, it just blows out cold air. Also my engine seems to be heating up more than usual. Never to the point of over heating. I also notice that the temp goes down while I am at a light or parked in general.
It was suggested that I check my heater core, that it may be clogged or need replaced. Whats your opinion? If this is the issue where is it located at?
