Our 1996 taurus had the battery replaced and both switches on the steering colum. The fuses wre also checked. The head lights work but not the turn signals or brake lights (bulbs were replaced) the power windows dont work and the radio.
Re: no turn signals no power windows or brake lights
Which switches on the steering column? Hope the switches were replaced with the battery disconnected. That alone could be the problem. Who did the switch replacement? If it was a business, you need to return to them and demand they do the work properly.
The turn signals and the emergency flasher are controled by one electronic flasher unit at the far left under the dash on the driver's side. It has a three wire connector and is attached to a mounting bracket with one screw.

I would check your brake light swich located under dash just fallow your brake pedle with a test light see if you have power going to it slitely press brake pedle see if other side of switch has power (key on car not running) if not try ajusting it by pulling on it or unscewing it if all checks out ok replace turn signal switch disconnect battery remove center part of steerring remove center bolt with steerring puller pull steering wheel with locking plate puller pull locking plate remove turn signal handle emergency button three scews holding turn signal under dash fallow steering colum disconect wires on right side (passenger side) tape a long wire to end of connector pull turn signal without pulling tape wire all the way out so you can tape it to new turn signal wire connector to be able to pull wires back down steerring colume (you might have to losen steerring colume and bracket two scews under dash four on steering colume)
General motors run the brake lights circuit throught the turn signal switch . Now if the fuse are all good for the brake lights and turn signal circuit . I would be looking at replacing the turn signal switch as they are known to short internaly. I am not sure on your model of car if you can just remove the steering colum housing around the switch or if you have to remove the air bag and pull the steering wheel to reach the turn signal switch . there is a turn signal flasher and a brake light switch also but if either of these were bad it would not effect the operation of the other
Sounds like a short in the steering colume, maybe the turn signal switch, or a wire that the insulation got wore thru in the colume. Unhook break light switch and try the turn signals and hazards again and see what happens, maybe you can isolate it that way. Also if you havent done it already chk.the sockets in tailight housing for corrosion and bear wires, or anything, even ground wires.
if the fuse is good then the multifunction switch is bad. this is the switch in the steering colum. this switch comes with the signal arm that comes out the side of steering colum as a complete assembley. the top and bottom covers of the steering colum must be removed to change switch.
Brake light switch, located on upper brake pedal should be checked, that is most likely your brake light issue, but U say tail lights aren't working, but running lights do, tail lights and running lights I would consider to be the same, so can u clarify that for me? Let me know how the u do w/ brake light switch, and if u have issue w/ tail lights?
i would check fuses for turn signal if ok check for battery power on both sides of fuse if you have battery power check the turn signal switch in the steering colum the brake lights run through the switch as well
