I have a 2008 Honda Accord that is not blowing out cold air. I first tried doing some research and purchasing a canister of R134a. I had an existing hose and gauge from my dad from recharging the AC on another car successfully. I turned on my car, turned AC to MAX, verified the compressor turns on, shook the can, connected the canister to the hose with the valve up, and then connected the hose to the low pressure valve on my car. After connecting the recharge kit to the car I see that the gauge says 0 PSI. I turn the valve and turn the can and get no change. I tried 3 canisters and got the same result. I tried purchasing a new hose and gauge and the result is the same but when I connect it I see 100 PSI. After driving the car for an hour and trying again the same gauge has the needle in the middle between 0-100 PSI. I can verify that the compressor turns on by hearing it turn on after pressing the AC button on and off. I can verify the self-sealing canister is letting out gas by hearing the pressure after having the valve up, the hose disconnected from the low pressure valve on the car, and then twisting off the canister.
I decided to setup an appointment with the local Honda dealership but it is going to be about 2 weeks. I am wondering if there is something else to try or how I can verify if the problem is located somewhere else. I am thinking about trying to purchase a can of A/C Pro and see if I have a different result, or possibly purchasing a vacuum pump and manifold gauge set for further troubleshooting.
Any advice is appreciated, thanks.
