I'm not sure what you mean by skips, it could be a cylinder missfire, it could be a bad coil or ignition wire

Hello: Yes you can do that but you will have to use 1/2 inch rope and go around the pulleys in the same manner the original belt went but skip the a/c pulley/ pull the rope tight mark it, the take it to a aftermarket parts store an measure it, subtract one inch and see if they have a belt that length, it may require more than one trip to get one that will work. There is not a listing for a belt to by pass the a/c compressor.

if it hasnt been ran for 2 years, i would drain the gas. put some 90 octane gas into it with some fuel injector cleaner if it still dont start, check the fuel pressure by disconnecting the quick connector from the fuel rail should have 35-40 lbs of pressure if it is way low or none fuel pump is bad

Always

TRY THIS REPROGRAMMING PROCEDURE. SWITCH THE IGNITION OFF TO ON 8 TIMES WITHIN 10 SECONDS. DOORS SHOULD LOCK THEN UNLOCK. PRESS ANY BUTTON ON THE FIRST REMOTE TRANSMITTER. DOORS SHOULD LOCK THEN UNLOCK. IF YOU HAVE ANOTHER CAR REMOTE REPROGRAM IT THE SAME WAY. WHEN DONE SWITCH IGNITION SWITCH OFF.

If you have a manual system, you have a resistor. If electronic, you have a blower motor speed controller. Please rate if this helps.

here is info:

Control System Outputs-Manual A/C
Blower Motor Switch Resistor
The heater blower motor switch resistor has the following features:

• The assembly is located on the evaporator housing in the engine compartment.
• Three resistance elements are mounted on the resistor board to provide four blower motor speeds.
• Depending on the heater blower motor switch position, series resistance is added or bypassed in the blower motor circuit to decrease or increase blower motor speed.
• An overheating protective device (thermal limiter) will open the resistor coil circuit when the temperature reaches 121°C (250°F) interrupting the blower motor operation in all speeds except HI.
• The thermal limiter cannot be reset and is not serviceable.

Control System Outputs-EATC
Blower Motor Speed Control
The blower speed control is located on the evaporator housing in the engine compartment.

• The function of the blower motor speed control is to convert low power signals from the electronic automatic temperature control module to a high current, variable ground feed for the blower motor (18527).
• The blower motor speed is infinitely variable and is controlled by the electronic automatic temperature control module software.
• A delay function provides a gradual increase or decrease in blower motor speed under all conditions.

It should be underneath the back and you should have a tool to crank it down to the ground, take off the cable and your done.

This is a very common problem with many of the mid 2000 Ford truck and SUV overhead consoles. The console is very prone to internal failure. If the dome lights work but the compass unit does not then it is a faulty computer unit. I offer a reasonable repair service with a lifetime guarantee, check it out: www.autoclockrepair.com
There is a bunch of useful info there. Drop me an email if you have questions, thanks!

they are right ,the immobilisor shuts its off ,including the fuel pump,try teh spare key and if no joy give both keys to the dealer to be reprogrammed ,if it starts with the spare key the chip could have fallen out of the key somewhere ,but it is a dealer only job

The Code 37 is a problem with the passengers Airbag. This is a repair for an expert because you do not want it to deploy while you work on it. You may though be able to switch off that side of the safety bag and have the warning light go out.

For the engine speed up there should be no connection. Both Autozone and Oreillys will do a free scan on your vehicle to diagnose your engine problems. If you get a defect Code from them you can follow their advice or use the reply function to contact us for more help.

I hope you find my Solution helpful. There was a TSB 04-26-12 about connections for the Airbag circuit, Published 12-31-04. It may jog the memory of the Dealer and help them repair you car.

You need to "hold the fan" (with gloves on) while loosening the four bolts behind the fan blades...the blade and pulley will then pull off exposing the water pump bolts...:)

Since your lights don't dim when you turn the key, the starter isn't getting power at all. There is a large cable that runs from the battery to the starter, it should have battery voltage at all times. If it does, then check the smaller wire at the top of the solenoid, it should have battery voltage only when you turn the key to start. If that wire doesn't have voltage when you turn the key to start, look under the dash on the steering column. There should be a thick wire (about 12 gauge) that is red with a light blue stripe. This is the start wire. Test it for voltage when you turn the key to start. If you don't get voltage there, replace the ignition switch. If you do get voltage there, try starting it in neutral. The gear selector switch interrupts the starter circuit if the car is in gear so you can't grind the starter in gear or start it in gear. If this switch gets a bad spot on the contact, it can keep it from starting. It will only allow the starter to work in park and neutral. If it starts in neutral, then you need to replace the gear selector switch. If you get voltage at the ignition wire under the dash and it won't start in neutral, then you need to trace out the wire from the starter because it has a break in it and will have to be replaced.

probally not but might need new cap

search for car speakers on ebay, or go to www.crutchfield.com both places have grids where you can find the size of any speaker in any car.

You have low oil pressure. It can be nothing more than the oil pressure sending unit is leaking or defective or a bad filter. Remove the filter and install a Motorcraft, Purolator, or Wix filter. If that does not solve the problem, I would check the wiring and if it is ok, replace the oil pressure sending unit before looking for anything else. If that does not cure the low oil pressure then your oil pump may be weak or the oil pump inlet screen is clogged. Your car is 11 years old and if it has been neglected then that is a possibility. Do not drive the car with low oil pressure or you will destroy this engine.
