Replying to: bobw3 (Oct 12, 2009 6:03 am) I've found that letting the windows down for 30 seconds gives the A/C all the headstart it needs to cool the car off, on even the hottest (100-105F) days. Have you checked outlet temps with an A/C thermometer? With the recirc on, you should be able to get a deltaT (outside temp minus outlet temp) of at least 40 degrees--if it's not, then the system is not "functioning as designed." One thing that's been noted ad nauseam on fitfreak.net is that the condenser on these cars hangs unprotected behind the open lower section of the bumper, where it can easily be damaged by road debris. A brief visual inspection should make such damage obvious, though. |

FIT AC Solution I have a 2007 Honda FIT 75K miles and live and work in Riverside County, Ca (Inland Empire). It really gets hot here in the summer but no humidity. At about 70K miles it started blowing hot air when I would come to a stop. Here’s how I fixed this. First, we all know Hondas have weak AC’s compared to domestic vehicles. I have owned four, all have had weak ACs. BUT, here's an important way to improve the FIT and probably all other car’s AC performance. The AC condenser on the FIT is unprotected and sets very low to the ground. It picks up all the rocks and junk off the roads, especially freeways. This severely clogs/blocks the condenser channels and bends the fins of the condenser. Then, air is restricted and does not remove the heat off the condenser. So, if you have any miles at all on your FIT check your condenser. You'll notice the damage already. Your AC performance is being adversally affected by this. Spend several hours straightening out the fins as best you can and cleaning out all the small rocks, etc from the condenser channels using a thin firm wire or wiper blade steel strip. Then, spray water thru the condenser to remove all particles. Next measure the condenser, cut a piece of aluminum window screen to the measurements and paint it black. Do not use the fiberglass type screen. The aluminum type is firmer and will stop stones B4 they get to the condenser. Make sure you fasten the screen down, especially the bottom. Next, put a high grade heat reflecting limo tint on the rear window and rear door glasses. I have had a lighter tint on my front door windows for 2 years. So far the cops have not bothered me. Finally, put the same high grade limo tint from the rear on to the TOP of your windshield on the inside. Some state laws allow 12" but check your state laws for legality. In all cases, I think a certain amount is legal. Always place a fold out type sun blocker up aginst the insie of the windshield when parked. When 1st starting out, crack the rear windows to exhaust the hot air rapidally. I did all these things to my FIT and it really helped improve the AC efficiency. It is now very confortable, even when the temp iis >100 degrees. This should for you as well. Good luck. rr |
