What makes the heater work in 2003 Ford Expedition?
I am not sure what you are asking about, but I am pretty sure all heaters work from the heat of the engine. The water flows through and cools the engine off, then is cooled off with the fans in the front (by the grill). The air then flows through this water (the fan doesn't cool it off completely, just a little but below the temperature of the engine. The air then goes through the radiator and into the car. I am pretty sure that is how it works.

What could be causing the heater on a 1998 XLT ford expedition to bloe cold air out the front dashboard but the rear heater works fine?
I am having the same problem. The dealer wants to charge 100.00 to fix the one post which isn't horrible but I would rather have metal parts so that it doesn't happen again. D…o you know what the site is for the aftermarket kit?
Answer . \ndid the heater core start leaking? anyway you should have no problem with the air if you bypass the heater core.
Answer . It is on the passenger side behind most of the dash. Most, if not all, the dash has to come out to acccess to it. It is a major job. Good luck.

Check you heater blower motor.. This sounds more like the common blend door problem on this model. The plastic door is driven by a DC motor that is geared too strong for the …application. Over time the motor will overstress the door and break the connector. The same plenum box is used on the F150 and you can find information on the problem by searching for that model also. There is a video available on YouTube showing how to diagnose and repair the system. It is an expensive repair at the dealer, but you can repair it yourself with minimal skills. You can follow links on my bio page for pictures and additional information on how to diagnose and repair the problem.
sounds like GEM mod. is bad
Fram is only the name brand of the filter.... As long the year, model, engine size, matches it should fit.... Doesn't matter who make it...
Like on any other vehicle. You bypass heater core by disconnecting hoses going into the heater core and hooking them together. This is a temporary fix. If not fix by the winte…r you won't have any heat / defrost to help keep you warm and windows clear.. Caution *** . Never open, service or drain the radiator or cooling system when hot; serious burns can occur from the steam and hot coolant. Also when draining engine coolant, keep in mind that cats and dogs are attracted to ethylene glycol antifreeze and could drink ant that is left in an uncovered container or in puddles on the ground. This will prove fatal in sufficient quantities. Always drain coolant into a sealable container. Coolant should be reused unless it is contaminated or is several years old. . Heater Core. 1. Disconnect the battery ground cable. 2. Drain and recycle the engine coolant.. 3. Remove the instrumental panel.. 4. If equipped with the 5.4L 4V engine, remove the junction block splash shield.. 5. If equipped with the 5.4L 4V engine, remove the bolts and disconnect the cable ends from the starter relay.. 6. If equipped with the 5.4L 4V engine, remove the junction block bracket.. 7. Disconnect the heater core hose couplings.. 8. Remove the retaining screw and remove the A/C plenum demister adapter.. 9. Disconnect the vacuum line from the A/C plenum demister adapter.. 10. Remove the heater core bracket.. 11. Remove the 13 plenum chamber top retaining screws.. 12. Remove the plenum chamber top.. 13. Remove the blend door assembly from the case.. 14. Remove the heater core.. 15. The installation is the reverse of the removal.
what does it mean when this appear on the message board " timing 99:59:59: "?
The Heater core is difficult to replace on the F150 since it is buried in the plenum box. Getting to the core involves removing the steering wheel, steering column, complete d…ash panel, evacuating the AC, draining the radiator, and finally removing the heater box. Once you have the box out(8-12hrs), the core is simple to replace. You want to be sure that the core is the problem before you undertake this process. If there is a strong smell of antifreeze in the cab or a puddle of coolant on the floor, the diagnosis is easy. Check that the radiator is full, not the overflow tank, the radiator. On a cold engine you can remove the radiator cap and check the level. It should be full. If there is air in the system it will affect cab heating and engine cooling. Another good check is to feel the two heater hoses going into the firewall from a cold start. The hoses should warm up at about the same rate and get uncomfortably hot-close to radiator temperature. If the core appears to be OK, the next concern is with the blend door that diverts air through the heater core. This is a common failure on the F150. We have a video posted on our web site that shows how to diagnose and repair the system. Please follow my user name back to my bio page to find a cut-and-paste link to the web site. You are only a few clicks away from solving the problems.
Well â¦. These are the two answers I got from other websites.. Regarding; if I bypass the heater core will the rear heater still work. 1. It depends if they have the op…tional rear heat/air. If so they have 2.. 2. My 94 E-150 5.8L with optional rear seat Heat & A/C had a separate unit under the chassis - just about where the 2nd row started.. I figure I would share them.. Happy New Yearsâ¦ Al
Override button ? What is it supposed to override ? A little more detail please
What could be causing the heater on 2002 ford expedition to blow cold in the rear but the front heater works fine?
Blend Door Problem Your problem sounds like the common blend door problem on the Ford Expeditions, and Ford Explorer. The door is on a vertical axis and when it breaks…, it can swing back and forth randomly giving heat or AC or nothing. The difference on acceleration is the force placed on the door swinging it one direction. You can check the operation by fully opening the glove box, removing the actuator motor on top of the plenum box and examining the blend door axle (the actuator is under the unit on top of the hump behind the flexible black plastic cover. It is on top of the unit, behind the glove box in the 2002 F-350 though). Pictures of the common fail signature are available on the Related Links below. There are several "free" fixes that mostly are worth what you pay for them. The solution on the web site is solid and proven over hundreds of vehicles and will resolve the problem once and for all.
First have the radiator flushed in case their is trash that is causing blockage in the water system which is about $70.00. Next if that is checked and all is good the blend do…or could be broke and not switching from hot to cold when the temp select is adjusted common problem on these guys and you can get a stainless steel replacement for the plastic factory at heatertreaters.com $129.00. And if that needs to be done the dash must come out to replace the door. Heater Core could be busted. Ford has a fix now that the water system needs a restricting piece in the line for the heater core so the pressure does not bust the heater cores. to replace the heater core or blend door is about $700.00. Heater cores $40.00. I know this because I just done this to my 98 xp.
Check the fuses ( # 37 ) is a 20 amp fuse for the cargo area power point ( # 39 ) is a 20 amp fuse for the power points in the front and rear of the console ( or in the dash… if you happen to have the bench seat )
its under the passenger side of the dashboard
U might need new headlights
If the heater is not working in your Eddie Bauer edition Ford Expedition, your heater core is probably junk and needs to be replaced.
