I have a 2005 ford expedition, I removed and reinstalled the driver side seat. now the fasten seat belt warning is not working and the warning light on dashboard stays lite after it blinks 5 times.

check and test seat belt circuit some times debris can damage wiring under and at side of seat --seat belt clip lock can go faulty

Belinda, could be a bad wire,plug,seat belt switch/sensor. Have a good tech. diagnose and estimate repair. Check the attached links,instruction and guides, Good luck

The seat belt warning chime is controlled by the central timer module ! You can't just disconnect fuses , other things may stop working !
Safety Belt Warning Indicator Lamp and Chime
The safety belt indicator and chime feature is controlled by the CTM. The driver safety belt switch is hardwired to the CTM. If at any time during the first 60 seconds after the ignition switch is placed in position II, if the driver safety belt is sensed as being unfastened, the CTM will process the input, and in turn, output a signal to the CTM through a hardwired circuit. In turn the CTM will output a visual warning to the instrument cluster. If at any time during the first six seconds after the ignition switch is place in position II and the safety belt is not fastened, the safety belt warning chime will sound.
When the seat belt is connected the warning still chimes ? Could have code stored in the CTM .

Check Connections and/or Switch

The check engine light gets power from the same circuit and fuse as the seat belt and some of the other warning lights.
And the ground comes from the computer.
So if the other warning lights work, and the bulb for the check engine light is not burned out, the problem is in the wiring or in the computer.

Probably no need to see an expensive mechanic. My seat belt warning light came on a few days ago when there were four people in the car and the rear seat belts weren't fastened (I thought that was why it lit up). However, the light came on and stayed on when I was the only person in the car. Logically, it suggested a bad connection somewhere, so I checked the connector under the passenger seat and made sure it was properly fastened together. I then sprayed a small amount of WD40 into the female clasps of both front seat belt connectors, clipped and unclipped the belts a few times and the light is now fine. Try it - it worked for my 2003 Escape.

sound like a relay / turn off anything that makes noise and in the quite listen for a clicking noise when you push the button. Could be located under the hood on the drivers side or under the seats

these have a seat belt light that flashes and the bell goes off to remind you to put on your seat belt.

yes, the seat has to come out , you may possibly hae to pull the seat frame apart. make sre the vehicle is not equiped with seatbelt pre-tensioner.

From the F-150 Forums, since I just bought one and this worked!

This is straight from my 2009 f150 owners guide

Preperation
1. the parking brake is set
2. truck in park
3. ignition switch is in off position
4. both seat belts are unbuckled

Disable Belt-Minder
1. turn the ignition switch to the on position, DO NOT START THE ENGINE.
2. wait until the safety belt warning light turns off. (approximately 1 minute).
* step 3 must be completed within 50 secs after the safety belt warning light turns off.
3. buckle then unbuckle the seat belt nine times, ending in the seat belt unbuckled.
* after step 3 the restraint warning light, (airbag light) will turn on for three (3) seconds.
4. within approximately seven (7) seconds of the light turning off, buckle then unbuckle the safety belt.
* the restraint system warning light will flash four, (4) times per second for 3 seconds for confirmation

you can do this for the passenger side also!!!


*NOTE
in step 3. after three times buckling and unbuckling the restraint warning light lit up in my truck. SO I WENT TO THE NEXT STEP, (STEP 4). waited 3 seconds and i buckled and unbuckled.

in the buckle /unbuckle procedure do it some what slowly and watch for the light. it may not take 9 times.
