I just picked up a 95 thunderbird lx with a 4.6 and a few things are wrong with it, it has 227k and it has a hesitation under heavy acceleration from a dead stop but above 2k rpm it has no hesitation. Also the heater blower motor dosen't turn on at any setting. And the power mirrors, dome lights, and the center consle lights don't work. I have a car show/cruise that starts in about 6 hours and would like to fix everything that I can.

coil pack, spark plugs, spark plug leads would be a few of the 1st things to check

Well the two circuits are not connected.
Are you getting power and a ground from the horn pad at the horn relay ?

sounds like low idle control sensor ! when car acting up could sstop by parts house get them to plug computer in and see if any codes have been stored even though the engine light not on at this time

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

this list gos from most to least likely 1 Inspect Throttle Position Sensor Faulty or Incorrectly Connected Throttle Position Sensor.
2 Inspect Mass Air Flow Sensor Damaged, Loose, or Faulty Mass Air Flow Sensor or Circuit.
3 Inspect Choke Thermostat Stuck or Improperly Functioning Choke Thermostat.
4 Inspect Air Cleaner Tempature Sensor Damaged or Faulty Air Cleaner Tempature Sensor.
5 Inspect Fuel Filter Clogged or Dirty Fuel Filter.
6 Inspect PCV Valve Plugged or Damaged PCV Valve.
7 Inspect Carburetor Worn, Faulty or Damaged Carburetor.
8 Inspect Fuel Injector Dirty or Worn Fuel Injectors.
9 Inspect Hose (PCV)at Clogged or Collapsed PCV Hoses.
10 Inspect Fuel Pump Faulty Fuel Pump.
11 Inspect Fuel Pump Low Fuel Pressure.

this is a long list i know but this is every thing that would cause this but it go's from most to least hope this helps

Change the 95 wiring harness to the 96

you have a vacum under the hood pluged into the wrong spot

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.

Your crank sensor may be really dirty and can't get a good signal from the reluctor near the balancer. Check the wiring harness to it as well. You may need a new crank sensor.
