Hoping someone can help. On the first hot day of rhe year I noticed that my air-conditioning has developed a split personality. The left vents are blowing cold air as expected but the right vents are blowing warm air. Max cool setting is not enough to cool the cabin.

What could be the cause and how big a job is it to fix?

Thanks in advance.
