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.
