Question about 2002 Ford F150 Regular Cab

2 Answers

2002 ford f-150 xlt extended cab - there is a beeping sound after I start the truck and it is not the seat belt sound. It stops after it has warmed up for about 4 min and will not come on again unless I have been driving for 30 minutes. I can't figure out what it is for and I don't have a owner's manual. I have have the this truck for 6 years and it has never done this before. Do you know what is causing this problem?

This is either going to be your anti theft system or your airbag system. If you have backed into anything hard or someone may have hit the truck in a parking lot it iwll be your Airbag. Your can deneergize the air bag system and if the beeping continues on next start up it is the antitheft.

I had this same problem. it will beep five times wait five seconds and beep again. it will do this five times. i thought it may have been my turn on/off airbag switch because the ight would not turn on. so i took that circuit board but that would have to be taken to a ford dealer so i just put it back in and dealt with it. this past week i went to florida for 7 days and my truck sat at home without being started for 7 days. now the beeping has stopped! but now the air bag light has come on. im not sure what to do about this. but at least its not beeping anymore.

You will need to determine if you are lacking spark or fuel when the engine is warmed up and fails to start. It could be the coil, ignition module, a relay, or various other components.

The 2002 Ford Ranger XLT airbag light blinks

The airbag is there, what's most likely wrong is the key switch may be going bad. Take your Ranger to a reputable mechanic and ask them to check it...unless you have an OBD II or a multimeter.

Westin nerf bars

Send them back and get the extended cab bars. if you have doors behind the passenger and driver seat it is the extended cab. If you don't want to do that, if you know a welder, they can weld them on for you.
