2003 Honda Accord has been dead all winter and now wont start with new battery

Yes, with the battery being disconnected that long, you need a mobile auto electrician with a pro grade scan tool computer to diagnose all the issues and do the programming of modules that are lost..

Car won't start and alarm is going off

This is an anti-theft measure. Usually, there is a code to input in the radio/display to disable it. If you can't find it in your owner's manual, you'll need to contact a dealer to get the code.

There are some folks who sell the codes online. Beware of scams with that.

Hello, I have accord 2003 2.4l with 99,000 mileage

Oil Viscosity In addition to meeting the SH or SJ classification of the American Petroleum Institute, your oil should be of a viscosity suitable for the outside temperature in which you'll be driving. Oil must be thin enough to get between the close tolerances of the moving parts it must lubricate. Once there, it must be thick enough to separate them with a slippery oil film. If the oil is too thin it won't separate the parts, if it's too thick it can't squeeze between them in the first place either way, excess friction and wear takes place. To complicate matters, cold-morning starts require thin oil to reduce engine resistance, while high-speed driving requires thick oil, which can lubricate vital engine parts at temperatures up to 250°F (121°C). According to the Society of Automotive Engineers' viscosity classification system, an oil with a high viscosity number (e.g., 40) will be thicker than one with a lower number (e.g., l0W). The "W" in l0W indicates that the oil is desirable for use in winter driving. Using special additives, multiple-viscosity oils are available to combine easy starting at cold temperatures with engine protection at turnpike speeds. For example, 10W-40 oil will have the viscosity of l0W oil when the engine is cold and that of 40 oil when the engine is warm. The use of such oil will decrease engine resistance and improve your gas mileage during short trips in which the oil doesn't have a chance to warm up. Some of the more popular multiple-viscosity oils are 5W-30, 10W-30, 10W-40, 15W-40, 20W-40, 20W-50, and 5W-50. Consult your owner's manual or a reputable oil dealer for the recommended viscosity range for your vehicle and the outside temperature in which it operates.

Ive 07 accord and only driver side window is

Thinking is just guessing , Testing needs to be done ! Your best bet would be to take it to a qualified repair shop. You have no idea of the electronics involved . Looking at a wiring diagram i see door multiplex control module ,C.A.N. - B communication line . Do you know what these are ? Related Terms. A controllerareanetwork (CAN) is a serial bus network of microcontrollers that connects devices, sensors and actuators in a system or sub-system for real-time control applications. There is no addressing scheme used in controllerareanetworks, as in the sense of conventional addressing in networks (such as Ethernet). When you push a button for one of the other windows the door module computer sends a message on the can bus to the other door module ,which ,if on line will open that window . Hooking up a factory honda scanner to see where the message is getting lost at , checking for DTC'S - diagnostic trouble codes . is what needs to be done to find the problem . Resetting ,there is nothing to reset .

2003 Honda Accord A/C problem. My 2003 Honda A/C

Hi first this I would do is call Honda corporate in New Jersey's and tell them what is going on and you have spent all that money with the dealership to have it fixed to only be told that they can not figure it out , I used to work for a Honda dealer 15 years ago and I can tell you that the dealership can call corporate Honda in Jersey and get their tech-support on the phone to help them with any problem they are having with a Honda, corporate in Jersey will not tell you they can figure it out they will figure it out. They are the maker of the car you are having problems with and you have given the dealership your hard earned money to have you car fixed. Really please call Honda corporate on the phone and tell them what's going on and how much you gave the dealership to fix it. When you call make sure you ask for tech support, they are really good guys , Really let me know how you make out.

Hi i have a 98

NEVER swap rear tires... the radial tires are not made/designed to be driven one way and then driven the other... they WILL delaminate and come apart.. when you rotate tires, you rotate front and rear on the same side....(old bias-ply tires were rotated around a vehicle) ... if you did not have both sides of the rear brakes fitted with new pads and ..at least had the rotors turned.. do that. look closely at the inside of your wheels and make sure there has been no contact.... once you have made sure both sides are good.. reply back to me on here.. thanks... please mark as helpful.. thanks

I have seen issues like this on other Honda's and the problem turned out to be the ignition starter switch. Do this, jumper power directly to the starter solenoid trigger wire and see if the engine cranks.

03 honda accord v6 shifting problems

Sounds like it could be the ECU (electronic control unit); easy to change. I have bought used ones a lot cheaper than new ones and work fine. Your year may be located under the glove box to the right behind panel (my older car was passenger side under the mat). They are easy to change out regardless of location.
