1983 320i BMW Hazard Button malfunction

Yesterday, I pushed in my Hazard Button on the dashboard in the middle of the heater system on my 1983 320i BMW. I cannot get the button to depress back in and stay off, it just keeps popping back out and staying on when the ignition is on and off!
I took out the fuse that indicated light for Hazard button and it made the Hazard button go off when the car is turned off, but when i turn the car on it returns to being on again! what is going on?

Replace the hazard button itself. Common problem on 1980's BMW's.

Probable part number: 61 31 1 364 525
