Question about Cars & Trucks
We put on the bypass pulley and now the fans are not running. Does anyone know what it could be?

I don't think you can bypass the compressor.
Chrysler would have to build a model without ac and as far as I know they all have ac.
When they do have an engine without ac they usually have an idler pulley to take the place of the compressor.
Re-routing the belt runs the risk of turning the alternator or water pump in the wrong direction.

On the 1999 Dakota with the 3.9liter, the fan shroud absolutely DOES NOT have to be removed. Very simple job. Simply use a breaker bar with a 15mm socket on the belt tesioner pulley nut. Using the breaker bar push (as though tightening) the pulley nut...the reaction will be that the tensioner removes tension from the pulley and the entire belt can be removed by easily slipping it toward the front of the vehicle...comes right off. The new belt can go back on in exactly the same manner. By the way the belt routing diagram IS CONVIENENTLY LOCATED between the hood latch and the radiator mounting for simple and quick refernce...one person job, I did removal and installation four times in less than 10 minutes. (why four times? The auto parts store was selling replacement belts that were too long and did not allow the belt tensioner to provide suffiecient tension...I had to try four different manufacturers before the tensioner was adequately tight with room to grow as the belt naturally stretches from use.). I found no stringing around the fan is required because of the way the belt is routed (it doglegs around the main engine pulley which is centered below the fanhousing and then the belt runs from there to the left side of the fan housing...avoiding the fan/fanhousing all-together (sure you can try to go past the fan/fan housing if you so desire...but you dont have to...and besides the space between the pulleys and the fan is ample to allow the belt to pass between with minimal interference or a simple rotation of the fan as you attempt this method. One hint that made my installs easy as pie...the last pulley you put it over should not be a bezeled and ridged pulley or you will needlessly make life difficult for yourself...the last pulley should be the water pump pulley which is a smooth bore and non-ridged pulley (makes you wonder how the belt even stays on it!)...making it easy as pie to slip it right over...as your last act of defiance to that mean old serpentine belt!

there should be a manual bypass to remove the clutch to the compressor otherwise measure the belt and go about 10 inches or shorter (just a hint to get the belt off use the tire iron wrench and push the tension pulley toward the cab of the car the thread is reversed)

I doubt anyone knows that off the top of their head. You could run a string through the path you want the belt to take and measure how much string it takes. This will give you an approximate length for the belt -- most parts stores could find one close to that size.

The easiest method to do this is to go to an auto parts store and buy a belt designed for a truck with no air conditioning. The belt will be the right size, and you just install it as normal, and bypass the compressor
