#2707 of 5207 AC button doesn't turn ON - 1995 Honda Civic DX
Jan 26, 2004 (9:05 am)
I own a 1995 honda civic DX. A month back my car skidded and turned 180 degrees and went out of the road. Nothing is damaged or hit by anything. Onething I notice is front bumper slightly moved it's position. My car is working fine apart from AC button not turning on. I took it to Michel's tires plus and they checked all the fuses and said everything is fine. They doubt on relay. I do not think either it is relay or fuses. I suspect some wiring connections might have got loose. I have very poor knowledge of auto engine. Anybody faced this before or suggest me where to take it to for diagnosis ???
Thanks for your suggestions.
#2708 of 5207 Knocking at less than 40 mph on '96 Civic LX
Jan 26, 2004 (10:25 am)
Hey everyone. My 1996 civic LX just started knocking when the car goes less than 40 mph. At first I thought it was an issue with my brakes because I was usually braking when I noticed that the car was knocking. Since then, I have heard this knocking when the car was sitting at idle. At highway speeds and on most roads where the speed limit is 35 mph, the knocking goes away. From inside the cabin, it sounds like the knocking is coming from the front wheel on the driver's side.
Does anyone have any ideas where this knocking could be coming from? Thanks for the suggestions.

One guess is that your Freon escaped possibly due from impact of accident. If you have no Freon the AC will not run. Take your vehicle to an AC repair shop. The AC will not light if no pressure in system.

Even if Freon is gone, the ac button should turn ON. Shouldn't it ? I understand if it is the case that AC button is ON and not getting the AC. It's like you turning on the light switch and bulb is not glowing.
Thanks for your reply.
#2711 of 5207 2004 Honda Civic Coupe EX 5-spd---NEED HELP!

Okay people. My new Civic is nearing 3K miles and I'm wondering about the oil. Manual says 5000. I drive my car quite a bit on the freeways (somtimes a lot faster than I should!). I'm getting antsy about the oil. Also, my gas mileage has been absolutely miserable (hovering 28mpg avg). I'm supposed to be getting 33/37. I tried for two tanks driving less agressively and didn't notice a difference. I switched from Chevron 89oct to Texaco 89oct. Again, no noticeable difference.
My questions are:
1)WHEN will my gas mileage improve? It HAS been very cold here lately (Richmond, VA).
2)WHEN should I change my oil??? I would think with all the metal filings from the engine changing at 3K would be better especially since I've driven my Civic pretty heartily.
Other than that, I'm loving my car. I HAVE noticed that parallel parking in this car is more difficult than any other car I've had even though it isn't much larger. I think it has to do with the high trunk lid. Has anybody else noticed this??? :-/
*sigh* Can't beat it though...I love my car.

A few things on MPG, the highway mileage is figured at 50 MPH not higher speeds. This lowers your fuel mileage. Also don't use a higher octane fuel, use 87, anything else is a waste of money and can get less mileage.
Also mileage will be lower since car is not broken in yet. Lastly, when its cold mileage is lower beacause of fuel formulations changed for winter for less pollution and especially if you warm your car up (0 mpg idling).
More freeway mileage even at higher speeds is better than city driving with regards to oil. 5000 miles is fine, however if you are uncomfortable then just change it. The idea of shavings is so old school from I don't know where. If you change it yourself, its pretty doubtful you'll see any. I would then worry... good luck
#2713 of 5207 A/c Regata
Jan 28, 2004 (5:39 am)
Regata, Snarks is correct, the A/c will not turn on if there is no pressure. Freon is mixed in with the lubricating oil and the system is designed to prevent self destruction. There is a pressure switch that will diasble the a/c compressor clutch from engaging when the freon is low. I don't know if the '95 were R-12 or R-134, if it is R-134, you can do a quick check for $10. Go to wall mart, find the discount section, last time i looked they had 16 oz bottles of freon R-134 and oil on sale there for $10. Charge up the system the a/c should work for a minute or so, before eveything has escaped. You may actually see where the gas is escaping. My guess would be that you need a new a/c radiator, I think it is called evaporator core, or condenser. Although I am pretty sure the condenser is on the cold side.

The refrigerant in Hondas since 1994 is R-134A, not R-12 (Freon). The service ports are different, so R-12 can't be introduced anyway, and trying to mix both will damage the car's AC system and any refrigerant recovery equipment used to service the system.
R-134 molecules are about 1/6 the size of R-12, and it's leakage rate is greater. On a car that old, it's likely that the system has lost it's charge.
If refrigerant pressure is less than 33 psi due to leakage or higher than 340 psi due to cooling blockage, the dual pressure switch on the condenser line opens the circuit to the AC control unit and stops the air conditioner to protect the compressor.
Time to take it in to a qualified shop and have the system checked.

I have a 2003 Civic EX 5 speed, which I purchased 9/03. My MPG's started out at 33, and gradually made it up to almost 40 at about 5,000 miles. With winter's arrival, and the oxygenated (winter) gas, my mileage has dropped down to 34-35 mpg. Mostly all highway, 75-80mph.
You don't need to use 89 octane gas. I'd recommend going with 87. High octane gas is useless, unless your engine is designed to use it. The Civic is designed to run on 87 octane. You might actually be harming your mileage by using the higher octane.
The oil change interval for the Civic is every 10k miles, or 5k miles for "severe service". I'm being a little more conservative - I'm going with changes every 4,500 miles.

Changing your oil and filter is cheap maintenance. You are going to read many different opinions on this board about this subject. The price of an oil and filter change at my Honda Dealer in Northern New Jersey is $23.00. We change the oil and filter on both our 2003 4 cylinder Accord, and our 2004 4 cylinder Civic every 3,000 miles. If we perform this service four times a year on each vehicle, the total cost is $184.00 for both vehicles. The oil is VERY clean on the "dip stick" of both engines, so as such, we know that we do not have any "sludge build up" in the crankcase of these units. We also burn 93 octane fuel in both vehicles, with an upper cylinder lubricant for the valve stems and piston rings. This is also a "personal choice"! We like the insurance of a little more octane when we "load the engine"! We also "warm - up" our engines in the morning to "normal operating temperature" before we drive the vehicles. These are the choices that we have made for the Hondas that we have owned or leased. Other people on this board have a different opinion on this subject, and that is "ok"! You now have heard another point of view. You make your own decision. -----Just my opinion. ---Greg
