    took it to the dealership, they read codes,cleared codes and reset them and couldn't find anything wrong. The warning lights/messages have stopped for some reason.
    Am wondering now if it's weather related

    it could be if there is a corroded ground wire and it gets wet it could cause a plethora of codes that mean nothing

Ford Freestar Message Center not visible. Need help resetting tire warning light.


You can't reset the tire pressure warning light (TPMS), when the pressure is adjusted or the sensor replaced (if the warning is false) the light will go out, there is no reset. Check the air pressure in all the tires, they should be about 34 PSI all around.

ESP/BAS, ABS, TCS, indicator lights came on at same time


Usually a bad wheel speed sensor. But when warning lights come on, there are always trouble codes stored in the computer. Get the codes read and then you'll know where to start your diagnosis.

2008 GMC Sierra 1500 50,644 miles check engine light is on stabilli track warning light is on traction control warning light is on engine runs rough and wont idle transmission shifts hard


This problem seems to be the ECM (computer) to have so many things acting up at the same time. Did it all start at the same time? Its possible that you can reset the ECM by removing the hot and ground cables, wait about 15 minutes and then replace them, may fix the problem, may only temporarily fix the problem if the ecm is bad or something is setting a code to cause this. It sounds as if it is running in limp mode. Have it tested at the nearest parts store. They should be able to decipher the problem.

Ignition warning light


If you have had no known problems such as unexplained battery drain, or power window cross opening (close passenger window from passenger seat and have driver's window open, etc.), your computer may need to be reset. Disconnect your negative battery terminal, take a half hour break (minimum) and reconnect the terminal. (Immediately) Drive car for minimum of 10 miles, preferably on open road (I have done this 10 mile drive three times to get a bad transmission shift back into line, after having the 2/3 servo replaced). Once the computer has gone through all its paces, the warning light systems, cruise switches and power windows should all function as designed. My cruise control had previously had to be turned on with the "Coast" button. Now it works again--as designed.

I have multiple warning lights rotating on and off, to include a flashing ABS light recently. All my guages read properly and my brakes a firm. I'm also experiencing an intermittent "chug" while going down...


hows the cars running voltage? a bad alternator or a bad body ground strap will do things like this. let me know what you find on the voltage and well go from there

Air Bag Light, Brake Light, & ABS Light came on in the dashboard.


Check and see if your alternator is charging
Low voltage will cause those lights to come on, as the computer is shutting down.

To check your alternator you will need a volt meter... WITH the engine running you should have about 14 volts coming out. IF NOT you need to replace the Alternator!

WARNING LIGHTS KEEP COMING ON!!!!


Sounds like the main computer has gone bad on you. You can try to have it re-flashed, it might fix the problem.
