1990 Ford Thunderbird Problems

What owners report

Owners of this model year most often describe two kinds of problems: electrical faults tied to the ignition switch and wiring, which in several complaints led to underhood or dash fires, and braking trouble involving the ABS system, where the pedal goes hard and stopping distance grows. A smaller but consistent group of complaints covers the automatic shoulder belts and unexpected high-idle or surge events. Reports span a wide mileage range, from low-mileage vehicles to ones well past 100,000 miles.

1. 1
   Electrical system

   Ignition switch and wiring electrical faults

   • 28 complaints (20%)
   • median 87,000 mi at 16.0 yrs old (3 state mileage, few)
   • 18 mention a crash, fire or injury
   • filed 1995–2006

   Complaints describe the engine continuing to run after the key is turned off, the battery draining, and sometimes smoke or flames from the dash or underhood harness area. Several owners link the damage to the ignition switch or the wiring fed by it, and a few report the vehicle was parked when the fire started. Some owners say they were told their vehicle was not covered by the ignition switch recall because of its VIN, or that the needed part was unavailable. Complaints are spread across the model's life with no clear mileage pattern in the sample; several fires were reported with the vehicle parked.

   Recall 96V071000

   What to check: Ask whether the ignition switch recall work (campaign 96V071000) was completed for this VIN, and have the wiring under the dash and at the ignition switch inspected for heat damage or chafing.

   2 excerpts from owner complaints in NHTSA records

   “1. Just suddenly started occurring. 2. Re: campaign id # 96v071000, I have an ignition problem with my 1990 Ford Thunderbird but was told by Ford my VIN does not apply to recall. Although no fire, I believe there is some sort of short circuit in my ignition switch. The automatic seat-belt will, at unpredictable times, not move into position when ignition switch is turned and at the same time the engine will turn over normally but will not start. Every time seat belt doesn't work, engine will not start. 3. …”

   NHTSA complaint #10142652, filed 2005-11, 74,000 miles

   “Vehicle parked in driveway 4 days. It caught fire. Fire dept distinguished the flames. Indication of fire origin was in the ignition switch fixed wires. Contacted Ford. Indicated recall was sent out. Been having problems with vehicle skipping & missing. Took to service dept & informed head gaskets had blown & water leaked into cylinder. No technical service bulletin for Thunderbird about head gaskets.”

   Seat belts

   Automatic seat belt and buckle problems

   • 19 complaints (14%)
   • typically at 6.5 yrs old
   • 1 mention a crash, fire or injury
   • filed 1995–2003

   Complaints describe the motorized shoulder belt failing to move into position, jamming in one position, or running continuously, and buckle or retractor problems where the belt will not latch or locks too tightly. Some owners connect belt failures with the car not starting or with the electrical system, and one describes a belt track motor repeatedly jamming against the driver. No clear mileage pattern in the sample; reports span the 1990s across many vehicle ages.

   What to check: With the door closed and ignition on, watch the shoulder belt travel through its full cycle on both sides, and test that each buckle latches and releases cleanly before buying.

   “Electrical short under the dash fire, wiring harness , vehicle was parked for a period of 40 min. Tt the consumer does not know what started the fire. The insurance was investigating the cause of the fire. The authomatic seat belt harness on the drivers side malfunctioned.”

   NHTSA complaint #973232, filed 1995-10

   “The front seatbelts do not latch properly. The buckle sticks and will not latch. Please describe. Tt the red release button sticks in the release position, this occurs with both and the driver and passengerside seat belts.”

   Brakes

   ABS pedal goes hard, longer stopping distance

   • 27 complaints (19%)
   • median 93,664 mi at 13.9 yrs old (1 states mileage, few)
   • 1 mention a crash, fire or injury
   • filed 1995–2004

   Owners describe the anti-lock and brake warning lights coming on and the brake pedal becoming hard, with the vehicle taking much longer to stop or not stopping as expected. Some complaints mention repeated replacement of rotors, pads and calipers, and others mention the master cylinder or the ABS relay and accumulator being replaced without solving the problem. Dealers are described as replacing components, and in some cases telling owners the warning light means the system is about to fail. Reported from roughly 80,000 miles upward and also on lower-mileage cars; no single season or condition dominates the sample.

   What to check: Have the brake hydraulic and ABS system checked by a shop familiar with the early Teves-style anti-lock setup, and ask for records of master cylinder, accumulator or relay replacement; confirm the pedal stays firm and the ABS light behaves normally on a test drive.

   “You know my husband and his friend had no idea ont his car that the brakes went out, until they were getting off the interstate, and it was too late. Wrecked into a semi-truck, that guy is lucky- so is my husband and his friend. I think this sghould be an issue of concern. Thanks.”

   NHTSA complaint #740925, filed 2001-02

   “Modual first failed sep 00. Car lost power steering and brakes at 60 MPH. Car was parked from sep 00 to 26 july 01 while Ford got part. New moduel was installed 26 july 01 and failed 8 aug 01 again at 60 MPH without power steering or brakes. Ford dealer is now looking for a new one. Part was listed at $100.00 at time of sep 00 failure. Modual obtained in jul 01 that failed in aug 01 cost $306.00”

   Vehicle speed control

   High idle or surge when shifting

   • 14 complaints (10%)
   • median 104,500 mi at 16.2 yrs old (2 state mileage, few)
   • 5 mention a crash, fire or injury
   • filed 1995–2006

   Complaints describe the engine revving up or the car surging when shifted from park into gear or while parking, sometimes leading to contact with another vehicle or object. A few owners report a sticking throttle or a pedal that would not respond, and some mention the brakes not holding the car during the event. Dealers are described as not finding the problem in some cases. Reported from low mileage (under 15,000 miles up to about 155,000), in parking and low-speed maneuvering situations rather than highway driving.

   What to check: Ask about the throttle linkage and idle control history, and during a test drive check that the engine returns to a normal idle when shifted between park, reverse and drive.

   “Car was backed out of garage. While in reverse, the engine began racing wide open, went across 2 driveways and hit another vehicle. Brakes would not stop it and would not go out of reverse. The only way to stop it was impact and turning the ignition off. This all took place in about 3 seconds.”

   NHTSA complaint #10108133, filed 2005-01, 54,000 miles

   “Brake pedal would not go down when brakes were applied. Also, throttle was stuck all the way to the floor. Dealer not aware of the problem. Occurred during very in cold temperatures. Problem still exists. Provide further information.”

   Exterior lighting

   Headlights flicker or cut out

   • 8 complaints (6%)
   • typically at 9.2 yrs old
   • 1 mention a crash, fire or injury
   • filed 1995–2000

   Owners report headlights blinking on and off while driving, especially at night or at highway speed, and in some cases the lights going out entirely. Several complaints point to the multi-function switch or the wiring harness behind it, with dealers replacing that switch in some cases. Reported at a mix of mileages throughout the 1990s; several owners noted it happened at night while driving.

   What to check: Check the headlights, turn signals and wipers with the multi-function stalk in several positions, and ask whether the stalk switch has been replaced.

   An excerpt from owner complaints in NHTSA records

   “Headlights blink on and off, especially on the highway, dealer had replaced multi-purpose function switch; manufacturer was contacted, and they had fixed the problem for her.”

   NHTSA complaint #821124, filed 1998-02

Buying note. Because electrical and brake problems dominate the reports for this year, it is worth having the ignition switch and wiring inspected and confirming the ignition switch recall status before purchase, and treating a firm brake pedal or an illuminated ABS light as a reason to walk away until diagnosed. Records showing recent brake hydraulic work and functioning seat belts make an otherwise old car much easier to live with.
