I was driving my 199 Pontiac Bonneville when he a/c blower turned off, then on again. When I got to my destination. I turned off the engine, no power to the car, but the blower was still running and wouldn't turn off. I had to pull the fuse under the engine for the a/c to turn it off. next day I put fuse back in but blower wont go on at all. What needs replacing?
