Most likely not
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

Try changing the #3 cylinder spark plug wire or all wires as you probabley have to buy them in a set.

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?
