I have a 2004 ford freestar after I turn the car off the headlight and interior light come on for about 30 seconds. Tired a few options is there any fix for this is it the alarm or the lighting module

Pull the fuse for your interior lights and check the back hatch it can cause this also

could you have a rodent in the system trying to get out

run the fault codes
could be a low coolant level sensor so check coolant level at the tank or radiator cap

does the car turn over still?? if not id say you need to replace the alternator and the battery, that will take care of your prob... but if it still turns over your problem is something totally different.. need clarification if vehicle still turns over.. hope this helps

I have the same Question .....WHERE is the front blower relay located? Not the resistor or the speed controller.....but the front blower relay!

this is in fact, part of your factory alarm... called PATS (passive anti theft system)

The actual "horn" should be coming from the rear right side of the cabin or behind the dash

This horn is built into the "computer" and there is little you can do at this point other than going to the dealer.

The dealer should be able to reprogram the modules in question to eliminate the "horn"

We stopped guessing about causes back in '96 when cars stored trouble codes. Get the codes read and post them. Then we can help

lighting control module if it has one.

Your car has a battery saver feature that shuts off interior lights if left on for over 30 minutes.

TRY THIS IN A GARAGE OR AT NIGHT..WITH THE INTERIOR LIGHTS ON..IF YOU PUSH THE SWITCH AND THE LIGHTS DIM IT IS THE REGULATOR..BECAUSE THE POWER IS GETTING DELIVERED..IF YOU PUSH THE SWITCH AND THE LIGHTS DONT DIM IT IS THE SWITCH ..DOUBLE CHECK ME ON THAT ..BUT THAT SHOULD BE CORRECT....
