No Blower in Floor Mode A customer arrives with a 1983 to 1995 Full Size Ford, Lincoln, or Mercury automobile with automatic temperature control. If the complaint is no blower operation when the floor mode is selected, the vehicle may have a problem with the thermal blower lockout switch also referred to as the CELO (cold engine lock out switch). The thermal blower lock out switch is located in the heater core intake hose. The two wire switch has a thermal element with a small set of contacts, the contacts are open when the coolant is below 120°F and closed when the coolant is above 120°F. The thermal blower lock out switch also contains a vacuum switch, which applies vacuum to the outside/recirculate valve when the system is in the floor position. When the engine coolant is below 120 degrees and the selector is set to floor position, the thermal blower lock out prevents blower from turning on and closes off the outside air during engine warm-up. When the coolant temperature is above 120 degrees, and the selector is set to the floor position, the thermal blower lock out switch allows the blower to operate and opens the outside air door. In order to diagnose this problem, test the thermal blower lockout switch with the engine at normal operating temperature (above 120°F). Unplug the wire harness connector from the thermal blower lockout switch. Using a 15-amp fused wire, jumper the harness terminals to test the switch. If the blower comes on, the thermal blower lock out switch is faulty. If the blower doesn't come on, look for an open between the control head selector and thermal blower lock out switch. In some cases the blower may continually run even when the engine temperature is below 120 degrees. Unplug the thermal blower lock out switch and if the blower motor turns off, the thermal blower lock out switch is faulty. If the motor continues to run, look for a short to power between the control head selector and thermal blower lock out switch
behind the blower motor. to take off the blower motor its on the passenger side under the glove box but above the floor. unclamp the casing where the floor light is. then theres the blower just unsrew the three srews. unhook the hose, unclamp it then then take it out
The heater blower motor is on the interior passenger side. It is kind of a round shaped housing facing the floor.
Remove the front floor kick-up panel.Remove the cover from the I/P electrical center.Remove the BLO MOT (blower motor) MaxiFuse No. 49 from the I/P electrical center.Remove the right side instrument panel lower insulator panel.Disconnect the blower motor resistor electrical connector from the blower motor.Disconnect the blower motor cooling tube from the HVAC module.Remove the three blower motor retaining screws.Remove the blower motor with fan from the HVAC module.
air flow is toward floor. blower is below filter. blower pulls air thru filter.
It's on the passenger side of the car.Behind the glovebox,you will have to take the glovebox off the dash.then you will have to lay on the floor on your back,looking upward by the firewall you will see the blower motor.look behind the blower motor you will see a wire harness conected to the blower motor.Thats the resistor,after you un hook it from the blower motor you will have to take the blower motor out.It's held in by three screws,once you have taken the blower motor out,follow the wire harness that you've taken off the blower motor.you will then see the resistor with much effort its easy to get out,it's held in with two screws,you will only take one screw out to get the resistor out.
The blower might need replacing. Normal cause is a failed blower resistor, caused by a blower fan that is failing.The resistor and fan are located above the passenger side floor behind the glove box.

Blower Resistor is located near the passenger side floor. There is a black cover over the blower housing. Remove the cover and you should see it. You may need to pull the carpet back to get access to the resistor. Also be sure to have a
The blower resistor is located under the dash, near the floor, on the passenger side of the vehicle. I had to replace the resistor about a year ago. It is not an easy place to work in. You have to remove the blower unit in order to get at the resistor. Not fun, but rewarding when you actually do it yourself.
On the outer side of the blower housing there is a small square tab, about 1/2 inch by 1/2 inch in size. Pull that tab down towards the floor board and turn the blower moter about and inch and it will release itself from the housing
