you dont fix serpentine belts. you replace them. open hood, although it is easier to reach the belt tensioner from under the car, you will need to route the belt from above. Take the tension off the belt tensioner (a breaker bar or rachet and the proper size socket with a pipe to give ya more leverage should work) and pull the belt while the tensioner is pulled away from the belt. to put new belt on, properly follow accesorie pulleys with new belt, leaving the tensioner pulley last once that far, take your breaker bar or rachet with proper size socket... and pull the tensioner away from the belt so that you can slip the belt over the tensioner, push the belt over pulley. release the tensioner and check to make sure the belt is seated properly on all pulleys.

The last Chrysler LeBaron was in 1995. Please check the year and ask a new question.
Chrysler has a belt and pulley kit to fix the problem. it removes the smooth surfaced pulleys and replaces them with grooved pulleys. the new belt is grooved on both sides
Either the belt is worn out or the tensioner is defective.

You need to make sure that the pulleys are all running in a straight line.
At a dealer... 60 for the belt, about 100 to put it on
The tension pulley that is on it has no grooves, it is a engineering mistake that never was recalled or improved; there was an aftermarket one that had grooves on it, more expensive and probably more difficult to get the belt on. I am going through the same problem on a Chrysler 3.0. Try using some belt dressing on the inside of the belt. I heard that the Goodyear Gator Belt is the best serpentine belt, though I have not tried it.
you fix it
Go to your local Chrysler dealer parts department and ask them if they can print a picture of it for you. Their catalog will show the belt routing when they look up the drive belt. i just did one ,i went to the local auto parts store and asked for a copy of their belt book diagram. 9 times out of 10 they are free and a great way to fix it yourself.
Disconnect the battery.Remover the serpentine belt.Unbolt the belt tensioner from the bracket.
Fit a new belt tensioner
Spray hairspray on the belt if it is making the noise or replace the belt or the pulley if its making the noise.
