I have a 2010 Toyota rav4 2.5 litter Sport model with 64K miles on it. The car worked well in the last 2 years but this year it didn't blow the cold air as it should. The only thing I can make the AC works is to reset the ECU by removing the negative cable from the car's battery for a couple of minutes then reconnected back to the battery. The compressor, fuses, and relays related to the AC in my car are working perfectly. Now if I want my AC working in my car, I have to do this in order to have the AC working. What's wrong? Thanks.
I had everything changed my compressor condenser new radiator valves and when charging it has ti much pressure on low side and it only cools when driving when idling it blows warm any suggestions

Thank you for sharing what we need to do if the air conditioner isn't blowing cold air. My car is a 2001 Honda Civic and recently, the air conditioner hasn't been working properly. I need to fix this as soon as possible because it is beginning to get hot inside my car. This six step process has been very helpful and I will definitely try this. If that is not the problem, I will have to call a professional to help me out! -Chris
