Question QUESTION: My 1998 Expedition runs great with over 250K. However, in the summer months when it gets above 85 degrees, it wont start. The THEFT light on the instrument panel blinks & I have to leave the doors open & let it cool sometimes up to 1 hour before it stops blinking & starts. I've had mechanics come look at it & of course, it's never that hot on that day & it starts right up. Any ideas? Maybe I should disengage the theft, but how? Thanks.
ANSWER: hey there, unfortunatly the anitheft cannot be disabled bery easily. do you have more than one key that you are trying to start this truck up with. if you use a wrong key or an unprogrammed key, the vehicle immobilzer thinks the truck is being stolen, so it will lock you out for a bit. let me know

QUESTION: I only have one key and it works fine as long as its not very hot. It only happens when its hot. From August to May I have no problem at all. If I park in the shade, I can usually start it, but not all parking lots have shade. I do use a sun shade & try to keep the windows cracked, that sometimes helps, but if the forecast is for rain & I leave the windows up & it doesn't rain, which happens alot here, then I'm stuck waiting for it to cool down on the inside of the vehicle. BTW...Thanks for getting back to me so quick.
Answer hey there. this is a very odd problem, and i have never heard of a complaint like this, i really dont think that heat would, r should affect anything in the security system, the only advid=se i can really give you is to take it to a ford dealer and have them scan the theft module for codes, if there is an oddball short or open circuit somewhere then it will throw out a code for the part that is faulty, the system does really not consist of that much so it cant really be to serious, sorry i cant be of much help but this is a problem that i would have to physically trace myself in person
thanks for asking
