My 95 Ford Thunderbird sounds like it has a bad bearing in the interior fan on the passenger side. How can I access to lubricate or replace?

Codes are set when a sensor detects something outside the normal range of readings. code 41 on a Ford eec_iv basically indicates the o2 sensor (front sensor, passenger side) is seeing a lean condition. Things that can cause a lean condition? Vacuum leak (bad hose, intake gasket, etc) Bad or dirty/clogged fuel injector egr valve not seating A bad sensor could cause this, but far more likely is the vehicle has an actual lean condition . (the sensor is actually working detecting the lean condition) this is just a short list of the few most common items that can cause a lean condition.

Noise usually indicates worn part. Lubricating it can help, but it won't solve the problem. Once a bearing starts to wear, it develops a flat spot on the bearing. If the wear is significant, rotating the tires individually off the ground will sometimes be enough to indicate if it's the wheel bearing ( you can hear/feel it at only one tire ) or a differential bearing ( you can hear/feel it on both sides of the same axel )

A bearing in the transmission or the transfer case will sound central to the vehicle...much easier to identify if a passenger in the vehicle can try to pinpoint the sound while the vehicle is being driven by someone else.

bearing come out on the side they went in.
bearings r 2 pieces, the bearing and its race.
bearing is held in by some bolt arrangement so removing that allows bearing to come out.
race is press fit and requires a removing tool or access to the rear of bearing, a hammer and something to go between hammer and rear edge of bearing - then tap around edge to move it out.

If it is only one side, it is probably the motor. If it is both sides, it is likely an electrical issue to the switch, or a bad switch.

Turn your A/C off, the compressor can make noise if bearings are dry or system is low on compressor oil.
Remove your serpentine belt. Turn pulleys by hand to check for roughness. Bearings in those pulleys routinely go bad.
You may get computer warnings with the following test, but with serpentine belt removed, run engine for 2 or 3 minutes. Do this on a warm engine after serpentine belt is removed. The warm oil will not mask the problem like cold thick oil can. Noise generated means problem is internal.
If this is a stick shift transmission sometimes the clutch bearing can make noise and is a sign that bearing is bad.

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

you can access the fan under the passeger side of the dash, also acess is formt eh firewall on the passenger side, pick your poison there, its hard to get to

Should be in the power distrubution box near the battery. Also, there is a fan control module mounted on the right radiator support towards the top engine side

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.

PART NUMBER PART NAME F6SZ-3F712-BB Electronic Variable Orifice Module OTHER APPLICABLE ARTICLES: NONE
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.

no as a matter of fact it is real simple nowadays...just remove the broken glass and go to the auto parts store and they have another one in a kit that glues right back on to the mirror... good-luck ray
