Air conditioning performance? 94-97 Accord (trying to figure out if I need R134a fill)
I have a 97 Accord with about 180K miles. I had my air conditioning
refilled with R134a two years ago. I almost always run the AC even in cooler weather. So perhaps its ready for another refil. I recently headed on a road trip through the Southwest. Its 110 degrees here in Las Vegas. The air coming out is only slightly cool and the interior temp is warm and and ranges from slightly uncomfortable to barely adequate. When the temp cools down to 95 degrees in the evening, the air from the AC gets quite a bit colder and the interior becomes pleasant. As a reference, my friend's 2003 Jetta blows cold even at 110. I am not sure if this problem is due to a fundamental weekness in the AC in Gen-4 accords, or if I need a refrigerant refil. I honestly don't remember how my AC performed in these temperatures in years past. Places around here in vegas want $130 just to even look at it (although it includes the refil). So I am looking for hear from Gen-4 accord owners who can verify the performance of the AC, before I go spend any money on this. |

It is most likely that your refrigerant charge is low, but that is only a
guess. A number of other factors can cause your unit to function poorly. You can get a charge kit, and try to top up your unit yourself. It is an easy job, and you can get a kit with can tapper, hose, gauge, and a can of refrigerant for about $20. IF a can or so of 134A returns your performance, it may last for a couple of months, or even more, before you have to pay someone to find the leak and fix it. And, then, it may not be that at all. |

Get the recharge kit or just the gauge from Wal Mart or elsewhere and read
the instructions. Check the pressure with the car running, air full on recycle and make sure the clutch is engaged. Gauge reading is color coded and idiot proof unless you are color blind....... > wrote in message oups.com... >I have a 97 Accord with about 180K miles.

Air conditioning performance? 94-97 Accord (trying to figure out if I need R134a fill)
Don, I brought it in to a trusted mechanic and he actually found that
at high temperatures, the AC fan didn't spin which was causing my engine coolant temp to rise in heavy traffic and to inhibit the cooling capacity of the AC. I had the fan replaced and things seem much better. Although, I am still not sure if it also needs a refrigerant refil. At high oudoor temperatures, the AC still seems to strain to keep the car cool enough. So I bought a small thermometer to attach to the AC vents. At 104 degrees outside, and with maximum blowing speed, I get only about 50 degrees sitting at idle or driving slowly in traffic. It does indeed cool down to 43 degrees when I am driving on the freeway (which makes the interior nice and comfortable). It goes back up to 50 degrees when again at idle. Would a refrigerant refil help keep the AC cooler at idle? Thanks again for your help. Don wrote: > On 2 Jul 2006 17:39:31 -0700, wrote: > > >I have a 97 Accord with about 180K miles.
