1999 Honda Acura AC Blowing Hot Air
Juan’s question:
My 99 Honda Acura’s AC isn’t blowing very cool. Especially in the afternoon when it gets hot outside. What should I try first to fix it?
Answer:
Odds are you’re just low on refrigerant. All Honda products leak a small amount of refrigerant as they age (toyotas may go eight years before needing refrigerant added, but many Honda products will need it added every couple of years or so.) Have the AC system evacuated out, then have the factory load of refrigerant added back in. You can’t just top them up like people used to, because the 134A gas that cars use today is very particular about exact refrigerant levels to work correctly. I’ll bet you’re just low on refrigerant and that will fix it.
Answer: Those alarm systems check for electrical loads going on and off (like the door opening which triggers the door switch and makes the alarm howl.) SO, anything causing an electrical drain can make the car alarm go off. First, have your battery checked, because a weak battery can cause it, I see that a LOT. And in those Acuras, it’s rather common for the driver’s side door switch to cause the alarm to go off, as they wear more with time than the other doors. All that opening and closing of the driver’s door can wear the switch so that it turns itself on just enough to trigger the alarm. Good Luck hunting down the culprit.
