My dash unit blows out very hot air no matter if it's turned to cold,or even off on 1991 Honda Accord

My dash unit blow out hot air even when it's turned off, or turned to cold air. It's always very hot. Is there anything I can do or check to see what the problem is? Can't afford a high garage bill...due to being a single disabled mother.

Any advice would be appreciate.

Thanks in advance.
