We recommend taking the vehicle in for a proper diagnosis, as it may be something as simple as having a fuse or relay replaced. During normal operation, the compressor does turn on and off depending on outdoor temperature and the cooling load at the time. The other possibility is that an electrical connector or sensor was unplugged during the maintenance which could also cause your AC to stop working. I have a 98 buick lesabre custom and i change my compressor and everything and vacuum the lines out put freon in and it still blows hot air. I had filled up about 6 months ago and it was blowing cold up until yesterday out the blue. There is a door in your vents that controls whether the ventilation air blows over the heater or the air conditioning coils and it sounds like yours is stuck on the “heat” setting. I’ve noticed it happens more often when it’s really hot outside. I have a 2003 F 150 in my AC is not real hot but it barely blows cool enough to keep me from breaking out in a sweat if I didn’t have tent I’d be baking. Hopefully one of those components have failed causing your fan not to run. Please advise. Hello, seems I have same situation here in my Mitsubishi Pajero 2009. I am out of ideas as to why. Thanks for your question about Civic’s air conditioning. Please contact our technical support line at 888-863-0426 so that we can get a little better understanding of the vehicle’s condition and be able to make any appropriate recommendations. We recommend having the actuator re-checked. I bought a can of Freon to recharge the A/C, the gage was showing around 50 pounds on the low side which is suppose to be the correct psi for my car according to what I have read. If this actuator has failed it may be causing the problem you’re having. The other possibility is that your system is overfilled with refrigerant. I have topped off the oil though my oil level was never low to begin with. When I started car on Friday afternoon, I found it’s fan was “on” condition and it was blowing “hot air”. The other possibility is that the leak is in the evaporator which is under your dash. When car stops it goes back to hot. After the Red Angel has been added you should recharge the A/C system to its proper level. Hello BDP, The moisture in the air condenses as it is cooled and if the evaporator is too cold it will freeze on the evaporator. Now the light stays off when I push the ac button. We recommend having the Freon level checked, if it is not low then you are probably going to need a new compressor. When it’s 65- 80 degrees my a/c works great, ice cold! I have a 2000 Honda and it was not blowing any cold air. The problem you are describing sounds like a problem with your dual climate control unit. Thanks for your question about your Ford Mondeo Ghia. I turn the a/c on and off several times also but also warm air coming out. We recommend using the Red Angel A/C Refrigerant Stop Leak to stop the loss of refrigerant and return the system to blowing cool at all times of the day. You may want to have it checked by an A/C specialist. Make sure to enough airflow at the place where you’re drying it off. Based on your description, the most common diagnosis is a bad temperature door actuator if it does have dual zone A/C. You would only change the compressor if the pressure rise from the low side to the high side isn’t large enough and you would only change the evaporator if it was clogged or had a leak. i added freon , will be cold for a while next day will blow hot air? usually after a day or 2 of doing this the air will work up to a month and begin the process over again. The other possibility is a blocked or broken cooling fan. i have a 2000 hyundai elantra the ac blows cold only somtimes but more times then not it blows warm air and when it dose the car runs very rough i have tried the do it yourself recharge cans and it only woeks for a few days what could be the issue. I have a 2007 Hyundai Santa Fe, the air-con started making an intermittent oscillating noise when running. Hi, And I hear what sounds like a clicking so I get home park and pop the hood, now that im parked its blowing hot air and I hear the click. Can you advise me? It blows like normal just not cold. this could be caused by debris blocking the condenser or a failed cooling fan or cooling fan relay. I have a 2001 honda civic dx. Having the actuator replaced should solve this problem. This could be an indication that your AC compressor is going bad and putting an extra strain on the motor while it is running. Thank you!! I have a 1995 Saturn.sl2and we add freon yesterday and afterward it spilled out antifreeze and the Ac is still not cooling of it hot air wat can it be. The windows and cabin of your vehicle act a lot like a greenhouse when it’s left in direct sunlight. If it seems low, we recommend adding a can of the Red Angel A/C Stop Leak & Conditioner, found here on our website: http://store.gobdp.com/a-c-stop-leak-aerosol-00222/. Sometimes it does when my car is moving but when im idle it does not blow cold air. And also if I step on it, it starts to blow air for a couple of seconds and then gets cool again. It sounds like your HVAC and vent controls are kind of going haywire. You can check for both of these problems by measuring the high side pressure in your system. Its as if the compressor only work after the car is driving for a few minutes. I started to notice the temp gauge would sometimes move even with not having my thermostat replaced and my air would work, and some days the temp gauge wouldnt move at all and my air would not work. That would cause your system to reach the high pressure cut off on hot days after a few km of driving shutting the compressor off to keep the system from damaging itself. Thanks for your question about your Forester. AND THEN IT JUST DROPS TO 60 DEGREES ALL OF A SUDDEN. Remember not to be too harsh with the cleaning. I can’t afford a huge repair bill. My 2011 VW Golf’s A/C blows hot air when the ambient temp is ~100F. Drove it around for awhile and worked fine. A quick visual inspection of the condenser through your grill can help you tell if it’s blocked. If your high pressure is too low, then you may need a new compressor again. Could this be a pressure switch that’s gone bad ? Different vehicles have different fail safes so we cannot say for sure if a broken fan will keep the compressor from coming on. I was trying to find someone with a similar issue and the few people that seemed to have an issue similar to mine said they took their car in and because it only happens after a few hours of operation, most places told them they couldn’t identify any problems.
