Question about 2003 Honda Civic

2 Answers

My air conditioning doesn't seem to be working. It just blows warm air. I've checked the coolant, that seems fine and there's been no overheating. I previously had a Camry and it seems to me there was a little hose near the firewall that somehow became disconnected. Any ideas what might be the problem? My car has 92k. Maybe a recharge? Thanks, Traci

Hi Traci. Like Keith said, a freon leak can cause the problem. If you have corrected this, there are a few other options to looks at.
-Is the A/C compressor clutch engaging? (If not, the A/C clutch, the A/C clutch relay, low pressure switch, or the A/C dashboard switch could be faulty.)
-If the A/C compressor is engaging, you need a pressure gauge set to determine if the compressor is building pressure. Also, there is an expansion valve that can fail as well. This is the part that regulates freon flow and keeps the high pressure and low pressure sides separated.

I hope this helps. Unfortunately A/C systems have more than just a few parts.

With the vehicle cool, remove the radiator cap, and manually pump the lower radiator hose until all the air is out of the system. That is how you get the air out of the system. If it is still overheating from there then you should check the fan to make sure that it is working correctly.

It is probably the problem. To make shure that need to change the gaskets, one of the symptoms use to be thet the temp rises when you are running at speed 50+ average, where is supposed that the car gets a lot of air due by the speed and nobody thinks that will be overheated.

The air conditioning,the blower fan everything stopped working, on 2002 Nissan Sentra. Does anyone have any suggestions?


One suggestion. Have you checked the fuses ?

I would check the AC or blower fuse to start with. If you have the drivers manual it will show you where the fuse box is. Typically there are at least two boxes to check. One in the Engine compartment and one in the passenger cabin.

Look inside the lid of the fuse box to see which fuse may apply to the AC circuits or the blower and check to see if they are blow. the metal link between the two posts that plug in. If the link is missing you need to replace the fuse with one of the same rating. Make sure you know where you took the fuse out from and put it back in the same slot if its good. Check all the main fuses if possible to see if any have blown and replace if they have.
