SOURCE: I have 99 ford F250.The

do you have a source of vacuum? normal problem occurs on the vaccum line from the engine to the vacuum switch of the car. unplug the vacuum hoses from the rear of the switch and feel if there is hose that is sucking your finger. if there is none, then trace the line towards the engine firewall out to the engine compartment. it could be broken that is why it is stuck in defrost mode.

i hope i was able to help.
pls rate me..
tnx..drcool

SOURCE: radiator leak 99 Ford Expedition back drivers side

You are likely leaking coolant from a heater line or hose,check the hose that comes from the water pump{smaller of the two] and see if it has a leak in it or if there is just a loose hose clamp.If you can't find a leak in the hoses or any steel tubes then you need to take it to a radiater shop and have it pressure tested to see if you have a leak in the intake manifold gasket or maybe even the head gasket,good luck.

SOURCE: where is the egr valve on a 99 Ford expedition

The EGR valve is in a very difficult spot to work on. If the EGR is bad it will set off the check engine light and make the vehicle run rough or stall at idle. It really doesn't make it run rough while driving or accelerating. What are the conditions when the car runs rough?

2001 ford expedition has is missing


At one time there was a problem with a Radiator hose clamp on the engine side. The clamps were improperly installed and a small amount of Antifreeze would run onto the coilpak, short and crack it, and then short out a sparkplug wire. If the "Check Engine Light" is not on yet the clamp is a good place to start. Then look for water staining on the electric parts.

Both Autozone and Oreillys do courtesy scans for free. Even if the problem light is not on, you may catch something on a scan. If no luck with the scan, try using a spray bottle of water around the intake manifold gasket and vacuum lines. Do this with the engine running. Any gaps will draw in water and affect the engine speed. This will indicate loose manifold bolts, bad gaskets, and bad vacuum lines.

My 99 ford expedition 5.4 is running bad and it sputtering and shaking while driving?


you probably got a bad coil. The 99 5.4 has individual coils one could be misfiring, but you will have to hook it up to a computer.

Egr


if its a low flow code replace the DPFE sensor. If you do a resistance check of it it will prabably be out of specs. Also make sure the two hoses are hooked up and arnt cracked. Also blow thru each one to make sure the tubes going into the exhaust arnt clogged. Also make sure the grn hose going to the egr valve is plugged in. Also apply vacuum to the egr valve to make sure it holds vacuum. If it doesnt then the vlave is bad.

2003 ford expedition locker malfunction


Lack of power because of the vacuum leak wher the line is disconnected from. Start the engine and with hood raised, listen for the vacuum hiss fron it sucking air in and hook the loose line to that fitting where you hear the leak.
