This may be your problem.

FORD: 1994-96 THUNDERBIRD LINCOLN-MERCURY: 1994-96 COUGAR ISSUE: Steering efforts at low speeds may intermittently increase to the heavier for highway setting on some vehicles. This is due to electrical "noise" from the Vehicle Speed Sensor (VSS) being picked up by the Electronic Variable Orifice (EVO) module. The EVO module then interprets this as an increase in vehicle speed and reduces the steering assistance to the heavier for highway level.
ACTION: Replace the EVO module with a new module that has improved filtering for electrical noise. Refer to the following Service Procedure for details.
SERVICE PROCEDURE Replace EVO module (F6SZ-3F712-BB). Locations are as follows:

  • On 1994-95 vehicles, the EVO module is located under the package tray in the trunk.
  • On 1996 vehicles, the EVO is located under the heater blower case on the passenger side.
Refer to Section 11-02 of the appropriate year Thunderbird/Cougar Service Manual for additional diagnosis and repair information.

WARRANTY STATUS: Eligible Under The Provisions Of Bumper To Bumper Warranty Coverage
OPERATION DESCRIPTION TIME 960402A Replace Electronic Variable Orifice (EVO) Module - 1994-95 Thunderbird/Cougar 0.5 Hr. 960402B Replace Electronic Variable Orifice (EVO) Module - 1996 Thunderbird/Cougar 0.3 Hr.

1996 Ford Thunderbird LX V8 Automatic Transmission shudder

Check rear emergency brakes if you have 4 wheel discs. When soot and brake lining fall to bottom of assembly they jam and shudder until wheels start rolling fast enough to scatter debris.

Also if posi equipped there is a needed rear-end additive to help clutch plates work. Perhaps clean rear-end lube and additive is needed.

your rack and pinion steering assembly broke. If you know how to replace it, it needs a new one. Or take it to a shop. I hope this helps.

When the car is steered fully to either left or right it seems that the brake engages. the car just stops rolling.

You have a problem with the 4 wheel drive power transfer case clutch, get the fluid changed in it, that should help.

I have 1996 ford thunderbird lx 4.6 liter v8 engine and how do i remove power booster brake from the firewall!

Pull the vacuum hose off the booster. Disconnect the brake lines from the master cylinder. Remove the master cylinder. Remove the windshield wiper motor if it's in the way. Inside the car, disconnect the stoplight switch connector. Slide the stop lamp switch off the brake pedal just far enough for the outer arm to clear the pin. If you have cruise control, remove the speed amplifier. Remove the booster attaching bolts/nuts. Slide the booster pushrod, bushing and the nylon washer off the brake pedal pin. In the engine compartment, pull the booster forward and rotate it until it is free. Good luck!

Brake lights and turn signals won't work on a 1996 ford thunderbird

Check the fuse, then the relay in the power distribution box. Probably one of the two.

Steering problems

This is a symptom of a problem in your steering box. If you have checked your power steering fluid and it is ok, and you havent had trouble otherwise, you should look first to your gear box and then to your tie rod. Ahain, its likely the steering gear box.

Fading brakes on 1989 T-bird

Sounds like all your basic brakes functions are covered. I ran into this intermittant problem before, it turned out to be the brake proportioning's that block type valve with the electrical connector in the center. The steel brake lines from the master connect to it. The valve regulates the pressure between the front and back brakes. The valve maybe malfuctioning internally.

Steering is not smooth

If the steering wheel is turned without the engine running the power steering system gets air in the system causing jerky feel. It'll take a few days of driving it to work the air out of the lines again.
