If you are talking about the blower fan resistor, this regulates the speed of the fan and can keep it off completely. You would go to the blower fan and backtrack the wires to a place on the Firewall where a part is held on by 2 bolts and has 1 wire from the blower fan on it. There may be clearance problems with heater hoses and metal tubes in this area. The part is the size of a pack of cigarettes and is mostly hidden inside the duct structure. This is all under the hood work. Look online for the blower motor resistor for your make and model. You may find a video.

If light is on alternator is not charging recheck your steps for connections

Sounds like your multifunction control switch needs replaced. Its location is on your steering colum.

> idles up and down when sitting idle and the head lights and interior lights dim in and out Probably not a vacuum leak; this can be caused by an AC (also on 'defrost') cycling and with changing engine loading, it is normal for some variation in engine speed although a defective 'idle air control' will allow a fair change in RPM. The visible exhaust is likely purging the system from moisture (condensation) and not a sign of trouble.

There are no Ford V-8 Engines that have timing belts. The engine will have a timing chain.

6 freeze plugs

sounds like surpentine belt. go to autozone and buy some belt dressing and spray belt. but before you buy the soray first have serpentine belt checked for cracks and stretching. if cracked then buy new serpentine belt and replace old belt

At the risk of going to the offensive, sometimes it's the simplest thing - you ARE putting it in neutral, at a stop, engine running, with the brake pedal pressed, when trying to shift out of 4wd, yes? 2) Check for blown fuse for 4x4 shift module 3)This sounds dumm, but worked on my wife 99. I took it to a school parking lot, put it in reverse, floored it and pulled on the lever and it popped out of 4x4 4) The shift motor is bad. Replace it. Hope this helps.

Google search your car 1999 ford expedition owners manual and download it for free from ford then go to roadside emergencies the fuse box / power distribution box diagrams are there

What you have is one of two things. You have a sparkplug that is bad and or a cop (coil on plug) that is bad. A good way to figure this out is to go to autozone and have them do a code check. Sometimes a " check engine" light will come on and sometimes it wont. My check engine light never came on. It was missing but after aceleration or high rpm the miss would go away. I changed both the cop and spark plug and problem fixed. By the way coil on plugs are expensive. I ordered mine on the internet and saved over 75%. Best wishes and hope this solves your problem.

In order for this question to be answered, there are various questions to be answered. What kind of problem? Blower not blowing the heat out? Blowing air but it's not heated? It could be a number of reasons for this question, actually need more specific diagnostics of the problem, otherwise the list could be anything from.....Check the hoses going into the firewall, if they're not warm/hot check to see if the correct amount of coolant is in the radiator/reservoir system, bad thermostat, blower motor, blower motor fuse/relay bad, bad air diverter (moves the flapper inside the air box from cold air to warm air or outside air to recirculating air) heater core plugged, leaking heater core (again there would be insufficient coolant in the system).

Why? Resistor or fuse? If fuse, Owner's manual for fuse box location and fuse number. no Owner's manual? ManualsLib Makes it easy to find manuals http://www.manualslib.com/

Look on the engine block it will be right underneath cylinder 1 right below the head

If that was my symptom, I would remove the starter and have it tested at one of the chain auto parts stores. They do it free and will likely have a replacement unit on hand. This sounds like a motor with shorted windings; this would cause poor motor speed and a possible failure of the starter bendix to engage. Description: What is starter bendix Yahoo Answers

This sounds more like a faulty alternator. Sometimes an alternator can still produce adequate voltage and amperage to keep everything running, but they are governed by a voltage regulator. If the regulator goes bad, the alternator may have little of no output, or it will not limit itself properly causing gauge problems, and various light on the dash to not work or sporadically come on. I'd take the vehicle to have the alternator tested at least. Don't settle for one of the part store tests, they won't give you all the information you will need. A properly working alternator should charge anywhere between 13-14.6 volts and depending on the vehicle 90-150 amps. I hope this helps in some way

white and orange are your positive wires. You can buy some pigtails like this at a local car audio shop. No wire cutting involved, they snap right onto your factory connectors and aftermarket speaker terminals. Worth every penny.

No, they work or don't. They are for fuel, not spark. I have reset many of them, but I don't think I ever replaced one.

well let's see is it only one side or both sides ? this could be a blown fuse/s there could be blown out bulbs on one side or both or the brake light pedal switch has shorted out or a ground wire for the lights has come off this has a lighting control module in it if you change anything that's it but check other things listed first before you spend$$$ do not change the computer this has nothing to do with the lights go to the lighting control module and unplug it clean the connector put some conductive grease on it and plug it back in corrosion on the contacts can be stopping the electrical current transfer through the plug to the unit DO NOT CHANGE THE ECM/COMPUTER THIS IS NOT INVOLED IN THE LIGHTS /SIGNALS/BRAKE LIGHTS THIS IS ENGINE MANAGEMENT ONLY POST BACK WITH RESULTS AND WE WILL TAKE IT FROM THERE IF THE PROBLEM PERSIST STEPHEN

Check fuse box. you may have a short some where. Especially if fuse is gone and a new one also goes.
