It is very possible that your vehicle is afflicked with the leaky windshield disease. The lower driverside corner of the windshield leaks and drips into the back of the FUSEBOX the problems usually start with running board lights staying on , radio going off when starting to drive , to no gauges working or the starter turning while the vehicle is off, this may take out the 300 dollar gem module piggybacked to it. Best thing to do is use rubber floor mats after a decent rain you will see water right under the fusebox would be on the driverside floorboard. If this is the case , find a used one on Ebay, dealer cost is 174 dollars from the dealer and another 300 for the gem module if needed 50/50 chance, then put some plastic over the back of these components or better have the windshield replaced perhaps resealed.

2003 ford expedition starts after couple trys then runs great just having probles starting


The light is supposed to be on when the alternator is not charging the battery, IE not producing more power than the battery already has.
You may have to try to catch the system when the light is on to test output.
Do you know what fuel pressure is before and after cranking ? You could be loosing fuel pressure back into the tank, or it could be something electrical.

1998 Expedition: 2000 Ford Expedition I smell antifreeze with heate...


If you smell antifreeze it may be 3 possibilities: 1. you may have a leaking hose/hose connector , or water pump. 2. your heater core is bad and needs replaced. Unless you know what you are doing I would highly suggest taking to dealer for heater core replacement. The dash and steering colum has to be removed to get to the heater core. This is not an easy job believe me (about-900-1200 job). If you have your heater core replaced then also replace the climate control door. This is good preventative maintenance and also a a dollar saver. I would have a pressure check run on your radiator as a first thought. All you may have is a bad hose and that can easily be replaced.

1998 ford expedition: engine ovr heat light comes on- soon after heater goes from hot air to cold. Pull over cycle key all lights go to normal soon after heater goes to working. replaced radiator- fan...


Have you tried replacing the overflow tank cap. These don't hold pressure as it should which will cause the temp to rise. EX: the cap rating is 15psi, and the cap has a defect which only allows the cap to hold 10-12psi. That water has to be pressurized by the cap for the water not to flow out. Also, does the temp gauge reach a high level or just the temp light comes on. This will give a better idea of the problem. If the gauge is normal but the light is on, sounds like a temperature switch is bad.

Key for my 1998 expedition has stopped working.


the chip in the key is bad. you can try reprogramming it. If you reprogram it you have to reprogram all keys at the same time. Typically when it quits working the chip is bad unless there have been some other electrical problems.

When I turn off my ignition, my heater fan will keep running


I just started experiencing the same problem. Yes, typically after rainy days, I can never get the interior lights to go out after the ignition key has been removed. The car acts as if there is a door open. Now, my latest problem is with the heater fan. Of course, putting the control in the "off" position will turn it off but you can turn it on and off with no ignition key installed. I'm also having problems with my heater core too so it's been a pain in the but!!

I believe this problem has also caused my battery to die which is why I'm on this site in the first place!! I can't get into the car with the keys and the dead battery won't allow me to unlock the car!! When it rains it pours!!!
