20 Most Recent 2003 Ford Expedition Questions & Answers

If replacing the blower motor resistor (under the passenger side dash, mounted on the front blower motor assembly) does not fix the problem, then the other likely candidates are listed below. (in your case, since both the front and the rear blower motors are not working, it is most likely #1 or #2, but it could still be #3. Hope its #1 or #2, which are both inexpensive to replace: 1. Blower Motor fuse. The blower motor fuse is located in the ENGINE COMPARTMENT fuse box (not in the inside the vehicle dash panel fuse box). It is the 40 amp (Orange) fuse located in the 4th position from the metal clip side. To open the box lift the plastic tab on the box end away from the box, until the lid lifts up. It is hinged on the other end. The 40amp Orange Blower Motor fuse is sandwiched between 3 RED 50 amp fuses on one side, and a 30amp and siver-metal-cased, and 20 amp fuse on the other side, in the central column of the fuse box. This is the most common failure of the system. You can pull the fuse with a pair of pliers, and inspect it. If blown, the metal u-turn shaped wire ribbon in the fuse will clearly have a burned break in it. Or you can test it with the continuity setting of a volt meter. A good picture is available at the URL below. https://i.ytimg.com/vi/joAmtVZL_ck/maxresdefault.jpg 2. Blower Motor Relay. (Located under the dash, on the driver's side, to the RIGHT of the driver's steering wheel). It is in a block of 3 or 4 relays, see the owners manual for which one, or swap in a new relay to each of the 4 positions one at a time. All four relays use the same standard Ford relay component.) DO THIS STEP ONLY AFTER CHECKING THAT the FUSE IS GOOD (in step 1). 3. Blower Motor electronic speed control unit is bad. (under the dash on the passenger side behind the glove box. To get at this you must remove the glove box rear backplate (6 screws, 2 on the latch, 2 others on the top, 2 at the bottom on each edge. The one at the bottom console edge is hard to find, but its there.) Then unbolt and replace with a new electronic controller unit. Expensive from dealer, I would get one at a junk yard, self pull if comfortable with DIY, and otherwise pay more for it to be removed by the yard, or a yard puller hire-able employee.) Unbolt the controller, and unplug it, plug in and bolt in new one. ONLY ATTEMPT #3 if you have checked BOTH #1 and #2 first. #1 is by far the most common #2, next most common, the controller least common (but the do fail sometimes.)

"The hot water check valve line runs into the firewall..it goes to the port closet to the passenger side. The main vacuum hose from the engine runs across to the canister behind the battery. There are two check valves in the main line. 1st check valve is close to the engine and its just a straight valve and the other check valve is close by the computer and has a tee built in it. The tee part runs down to the only and last port running into the firewall and there you have. Air and heat coming out the vents or defrost when you command" Someone else did the hard work for me. Good luck.

Could it be the pedal extension malfunction....The button where you can bring the gas pedal closer? Just guessing

Said safety switch would normally be positioned in the edge of the body seam where the gate can close it. Sounds like it just needs adjusted out closer to the gate. If no adjustment, put a washer of some kind under it. Washer can be anything as long as the switch body is touching metal to complete the circuit when you push it back in.

Yes - there is a solution here.

The problem here is that you must leave continuous power to the radio. Any interruption causes the countdown or wait period to start all over again. The secret is to ensure the key is turned in the ignition to accessories point I or the first point on the ignition that activates power to the radio.

If the key is not turned in the ignition as outlined, the radio will automatically shut off after one hour which is a power saving feature (which is great) but it also has a side effect in this case of shutting off the radio before the time limit has been reached!!

Obviously - as you must leave the key turned in the ignition during the wait period (which may be up to 4 hours) please ensure the vehicle is parked in a safe location and well away from any opportunistic thief.!!

Hope it helps or for anyone reading this in a similar situation - this information applies to many vehicles and radio types as many manufacturers have a similar security feature - not just Ford.

Thanks for using FixYa,

If you're finding it difficult to service/repair your car, get one of those online manuals. You'll not have to wait for others to answer, or rely on mechanics and all. Plus i know a website that has very good manuals online, without expiry i.e. for lifetime. www.reliable-store.com
