Hello, I was driving around today and all of the sudden it smelled like an electric fire and my fans starting blowing smoke, any idea what it could be?

 

what year and model

 

1986 244 dl

 

On a 240 there is a dropping resistor the reduces voltage for speed 1,2, 3. 4 th speed is full voltage - So if the fuse is good, and it does not work on any speed your fan motor is fried. (unless there is simply a melted connection) If it still works on speed 4 - your dropping resister melted.

It's a complex job - I would charge 6 hours to replace a fan motor, resister and switch. Hopefully those parts are still available.
