A/C or Heater Blower Problem

They are plug and play units...passenger side of interior...usually behind a kick plate or bolted to the general area around the heater box

my heater isnt working. i replaced the blower motor but i had my brother in law check it and there is only like 4 volts going to the resistor where the blower hooks in. he says there should 12 volts going to it. is there something else causing the blower not to work?

That car has an independant rear suspension that has either been mis adjusted or something is broken. These rears have to be aligned just like the front suspension.

Removal

1. Remove the glove compartment liner to gain access to the heater blower motor and blower motor wheel assembly mounting screws.
   

1. Use a small screwdriver to remove clip retaining hydraulic damper strut.
   

1. Remove four screws and remove the heater blower motor assembly and blower motor wheel assembly from the heater blower motor housing.
   

Installation

1. Using a new seal, position the heater blower motor and blower motor wheel assembly to the heater blower motor housing with the flat side of the flange near the heater blower motor switch resistor (18591). Install the four retaining screws.
   

1. Tape the heater blower motor power lead to the air inlet duct to keep the wire away from the blower outlet during installation.
   

1. Install the heater blower motor and blower motor wheel assembly in the vehicle.
   

1. Install the glove compartment liner.
   

Provided the hose bib for the heater hose is still sticking out of the firewall the hose slips over the bib and then a hose clamp is tightened over the hose. But it's possible that the bib is broken off and then heater core is going to need to be changed

If it is slow,on all speeds,then the blower motor is most likely the problem,replace it.

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.
