Looking for the location of the fuse box on a 1998 ford windstar to replace a left turn fuse

If you have right turn signals that work it will not be a fuse as 1 fuse controls the whole circuit.

I would start by checking the bulbs and then the turn signal stalk itself.

There are 2 fuse boxes / fuse panels in nearly every Ford product: one directly above the driver's left foot (when the driver is actually sitting in the driver's seat). The other is inside the engine compartment, on the right side - contains high current fuses.
There is extensive coverage of fuses and the circuits each one protects Owners Manual.
See "Related Questions" below for sources of free online Owners Manuals for 1996+ Ford & Mercury products.
Checking & Changing A Fuse Inside the fusebox cover is a small white plastic tool for pulling fuses out.
Inspect the center section of the fuse to determine if it has 'blown' - it will be obvious if the metal strip has melted.
Insert a replacement fuse of the same color / amperage protection by simply pressing it into the fuse-slot.
Checking a fuse Generally, if a fuse is 'blown' you can tell by looking at the fuse. Look at the wire looking thing in the top on the fuse. It'll look kind of broken or burned or just otherwise messed up. If you're not sure what a good fuse looks like, go to an auto store and look at a new fuse. Then look at your fuses and compare appearances.
Getting the engine compartment Power Distribution box cover off There are actually two separate covers. One is for the circuit breakers and one for the fuses. There's a tab in the center that you squeeze together and it pops off. In the cover you'll find spare fuses and a puller. If you still need to get the breaker cover off, there's a tab on the corner marked "lift". With the other cover removed, you can then unsnap the tab and wiggle it out.

Answer Go to the dealer service dept and ask them to photocopy the diagram out of their service manual for you. They should do this for you with no problem.

Answer Under the dash just to the left of the steering column.
Underneath the drivers side kick-board / panel underneath the steering column.
One fuse box is located under the hood by the battery. Another is under the left side of the dash. Carl
Not real sure for this model but I think there is a fuse box by the battery under the hood and another one under the left side of the dash. Carl
power fuses are next to battery in a black looking contaner there is a lid that has to be removed. the regular fuses are located underneaath the dashboard on the drivers side above your left foot... if you are sitting in the van
there are two fuse boxes, one is in the engine compartmente near de battery, the other one is under de driver side near the steering column.
It depends on the fuse. Most of the fuses in use today are small plug-in plastic devices. Simply grab them with needle nose pliers or a fusepuller and pull them straight out. They are color coded as to ampacity. There are two fuse blocks in the Windstar. One is in the engine room by the battery. The other is under the left side of the dash. Enjoy.... Carl

Click on the link below Click on Owner Guides The owners manual ( which includes the fuse box diagram ) can be viewed on-line The interior fuse panel is located under the dash panel on the left side wall near the driver side of the vehicle. it is enclosed with a black plastic cover. The power distribution unit fuse panel is a black plastic box located in the engine area near the battery, the battery should be disconnected before replacing fuses in the power distribution unit according to the owner's manual. The fuse box is located on the drivers side about half way up from the floor, it is mounted on the side and is made of black plastic roughly 4 inches wide and 6 inches high. The cover just snaps on and off.
