90000 Miles on the Timing Belt. Do not let this go! A timing belt failure can cause internal engine problems.

Should cost around 200 or so, depending upon your local labor rates.

Good Luck!

SOURCE: Air condition is not cooling my car is Honda Civic 2003

Realize that auto AC is basically a refrigerator in a weird layout. It's designed to move heat from one place (the inside of your car) to some other place (the outdoors). While a complete discussion of every specific model and component is well outside the scope of this article, this should give you a start on figuring out what the problem might be and either fixing it yourself or talking intelligently to someone you can pay to fix it.Become familiar with the major components to auto air conditioning:
the compressor, which compresses and circulates the refrigerant in the system the refrigerant, (on modern cars, usually a substance called R-134a older cars have r-12 freon which is becoming increasingly more expensive and hard to find, and also requires a license to handle) which carries the heat the condenser, which changes the phase of the refrigerant and expels heat removed from the car the expansion valve (or orifice tube in some vehicles), which is somewhat of a nozzle and functions to similtaneously drop the pressure of the refrigerant liquid, meter its flow, and atomize it
the evaporator, which transfers heat to the refrigerant from the air blown across it, cooling your car
the receiver/dryer, which functions as a filter for the refrigerant/oil, removing moisture and other contaminants Understand the air conditioning process: The compressor puts the refrigerant under pressure and sends it to the condensing coils. In your car, these coils are generally in front of the radiator. Compressing a gas makes it quite hot. In the condenser, this added heat and the heat the refrigerant picked up in the evaporator is expelled to the air flowing across it from outside the car. When the refrigerant is cooled to its saturation temperature, it will change phase from a gas back into a liquid (this gives off a bundle of heat known as the "latent heat of vaporization"). The liquid then passes through the expansion valve to the evaporator, the coils inside of your car, where it loses pressure that was added to it in the compressor. This causes some of the liquid to change to a low-pressure gas as it cools the remaining liquid. This two-phase mixture enters the evaporator, and the liquid portion of the refrigerant absorbs the heat from the air across the coil and evaporates. Your car's blower circulates air across the cold evaporator and into the interior. The refrigerant goes back through the cycle again and again. Check to see if all the R-134a leaks out (meaning there's nothing in the loop to carry away heat). Leaks are easy to spot but not easy to fix without pulling things apart. Most auto-supply stores carry a fluorescent dye that can be added to the system to check for leaks, and it will have instructions for use on the can. If there's a bad enough leak, the system will have no pressure in it at all. Find one of the valve-stem-looking things and CAREFULLY (eye protection recommended) poke a pen in there to try to valve off pressure, and if there IS none, that's the problem. Make sure the compressor is turning. Start the car, turn on the AC and look under the hood. The AC compressor is generally a pumplike thing off to one side with large rubber and steel hoses going to it. It will not have a filler cap on it, but will often have one or two things that look like the valve stems on a bike tire. The pulley on the front of the compressor exists as an outer pulley and an inner hub which turns when an electric clutch is engaged. If the AC is on and the blower is on, but the center of the pulley is not turning, then the compressor's clutch is not engaging. This could be a bad fuse, a wiring problem, a broken AC switch in your dash, or the system could be low on refrigerant (most systems have a low-pressure safety cutout that will disable the compressor if there isn't enough refrigerant in the system). Look for other things that can go wrong: bad switches, bad fuses, broken wires, broken fan belt (preventing the pump from turning), or seal failure inside the compressor. Feel for any cooling at all. If the system cools, but not much, it could just be low pressure, and you can top up the refrigerant. Most auto-supply stores will have a kit to refill a system, and it will come with instructions. Do not overfill! Adding more than the recommended amount of refrigerant will NOT improve performance but actually will decrease performance. In fact, the more expensive automated equipment found at nicer shops actually monitors cooling performance real-time as it adds refrigerant, and when the performance begins to decrease it removes refrigerant until the performance peaks again.

SOURCE: 2003 honda civic how to remove door panel

Step one Look at the inside door handle. Behind it you should see a little cover, You pop that off and there will be 2 phillips head screws behind it. remove them.

Pop out the door handle, and unplug the power lock plug,

Youll also have to take the door lock rod, by spinning the plastic door handle 90 degrees until u can wiggle it out.

next remove the sail panel( The little triangle shaped piece in the corner of the door on the top, ( may have a tweeter in it) ( it just pops out)

Next take a screwdriver (flat head) and pry off the cover of the door handle, there will be
2 phillips head screw behind it ( remove screws)

Unplug power window connector (big green plug)

Now just start gently pry the door panel off with a screw driver, see if u can peek behind the panel and see where the panel clips are, and pry near those areas

2003 honda civic cuts out when wet weather or car wash


Could be two different problems.
The ignition system could be shorting out and shut the engine off when wet, and the serpentine belt could be slipping when wet which would cause the alternator not to charge.
The battery light should come on if the engine dies.

I have a 03 honda civicand the air conditioner wont work? it doesnt need recharged and the light comes on when i push the button but i get no cold air? any ideas?


I have the same problem right now, and from what I can figure, it looks like an intermittent thermal protector switch on top of the AC compressor. My 2003 Civic air conditioning works fine for 20 minutes or so and then stops working. If this switch is faulty, the compressor clutch won't engage and you won`t get cold air. I will get it replaced soon, but it seems like the access is not easy.

Change oil filter honda civic 2003


buy new oil filter, oil, and a new drain plug and gasket. the used plug is prone to leakage. remove drain plug and drain in a big enough pan for all the oil. oil filter is located on rear of engine. easier to remove from the bottom of the car. put oil on the seal of the new filter and hand tighten. replace oil plug with new gasket and plug and tighten to 33 foot pound. add oil that is required and start car. when oil light goes out shut car off and check oil add oil as needed.
