The signal light switch is part of the multifunction switch on the steering column.
The diagnostic port on a 94 Ford Taurus is located under the hood near the firewall usually on the driver's side. Ford started producing the Taurus in 1985.
the SHO model it came standard in 90-95 so the 89's dont have one. the 94-95 have hard button ones that dont break as easily
I had a 94 & 96 taurus and you had to take the ash tray out to get to it.
Probably a issue with the multifunction swith (headlamp switch). You'll need to test the switch.
My '94 3.8 uses 5W-30 according to the owners manual
The fuel pump is in the fuel tank.
Contact an auto wrecker or dealer for transmission applications. Ford made many changes to these transmissions.
Under the hood at the firewall passenger side.
most of the time its in the trunk on the side ....
i don't know about the Taurus but a thunderbird suspension will match up
My ford truck key fits and starts my taurus! But that might be because the switch is worn, but you might want to try a couple different ford keys before tearing off the steering column. there were answers for hard way also, here is one way that might work although it doesnt sound very easy to me: http://www.ford-forums.com/ford-taurus/4345-how-replace-ignition-switch.html
