2003 Honda Civic Owner Comments

problem #5

The air conditioner on my 2003 Honda Civic si stopped working suddenly after a loud breaking sound came out of the car. I took it to the Honda dealership and the diagnosis is that the compressor exploded and caused metal shaving to go into the entire air conditioner system. The dealership has told me that the air conditioner system will need to be totally replaced. The estimate for the work is $2600.

My air condition just died, its not a fuse, might be electrical, my mechanic says even after 7yrs it should not have died. Driving around in 95 degree weather, lots of rain with no defrost either. Wipers work, need help to fix this problem -expensive if its a sensor?do not know the problem at all.

2003 Honda Civic ex. No heat in winter. Overheats in summer. Coolant overflows through reservoir. Several others with this same problem. Its not the water pump, radiator, thermostat, or lines. Honda must fix this problem.

Air conditioning condenser is too low to the ground and fully exposed to stones, sand and road debris that kicks up from the highway. My condenser originally had black paint on it but it now is dented, leaks and looks sandblasted and is blocked full of road salt causing the defrost function and the air conditioning to fail and freon 134A to be exhausted into the atmosphere causing environmental damage because of this poor unprotected design. Recommend the manufacturer be compelled to make available some form of protective measure to prevent this premature failure of the windshield defrost function and air conditioning system.

In August of 2006 my vehicle overheated for the first time. I promptly took it in and they fixed an "air hose leak". after that my car overheated every few weeks without warning and after coolant had been found leaked into the engine a new thermostat was installed. It overheated a month later and the whole engine needed to be replaced.
