SOURCE: ENGINE COOLANT FAN NOT CUTTING IN

On my 2001 Focus Zetec 2.0L, the radiator fan only worked with the air conditioning turned on (as in no low speed - engine would overheat while idling or in traffic, but was fine as long as the A/C was on). The fix was to replace the radiator fan resistor assembly located in the fan shroud between the fans.

SOURCE: crown victoria window motor replacement

remove the door panel. be very careful and make sure you get all the screws out. Should be maybe 2 on the bottom half of the door, and 2 on the top half. one is right by the handle, which is the one i forgot the first time i took my door pannel off. carefully pull the panel upward, and outward at the same time. Once the panel is off, disconnect the controls, and remove the light from the panel. Remove the plastic cover very carefully, it will tear, just keeps noise, and air, and the elements out.
There will be 3 screws, they are torx bolts, once you pull those 3 out. They are located middle of the door towards the right side. The motor will drop down a little bit. disconnect the wires for the motor, and wiggle the motor off of the regulator. the crown vics have a decent size hole to get into the door panel, you can also remove the speaker if that would help you do it. other than that, it just lining up the new motor into the car, pushing it into the regulator, and putting the 3 bolts in, make sure they are snug, and not cross threaded. put everything back together, and your set.

SOURCE: Here's a wierd cooling fan issue

Thats not too weird as the car would kick on the fans at full speed when it detects a problem with the sensor. Your ECU is not reading the sensor properly and needs to be checked by Ford. I hope this helps you.

You'll find said sensor on the lower radiator tank. Just look for a wire connected to a sensor screwed into the lower tank and that's it.

Trouble code p1299


Your PCM is going into fail-safe cooling mode. If temps really are normal then you may have a bad CHT (cylinder head temperature) sensor. Disconnect battery (negative wire) for one minute to get rid of code then road test your car to see how soon the P code comes back.

Temperature gauge cold then back to normal


You have to make sure the thermostat is working properly and is the correct one. Idle the vehicle for about 20 minutes and then feel the upper radiator hose. It should be hot to the touch. Drive the vehicle and when the temp gauge falls to 'cold' stop and feel it again. If it is much cooler to the touch than before the thermostat is defective or wrong.

1988 crown victoria 5.0liter engine, idles rough and dies when slowing down or stopped. sparkplugs have a black coating on them.what could be causing this problem


Usually when there is a black, ashy coating on the spark plugs, this indicated that the engine is running rich. This can be caused by a few things, including a faulty coolant temperature sensor that may be indicating a cold engine when it's in fact warm. A bad oxygen sensor can also cause some engine enrichening as well. These are just a couple of things you may want to check.

Please let me know if you need any further assistance. :)
