With my 07 Odyssey, the AC will work fine (with nice cold air coming out) when the car is first started and will work for maybe 5 minutes or so. Then just warm air comes out of the vents. When the air turns warm, the compressor does not go on when the AC is on. Same thing happens whether the blower fan is on high or low.
I called repair shops, and they want about $100 to test it and said it may just need more 134a refrigerant. But if that was the case, wouldn’t the loss of cold air been more gradual and permanent? Now it works fine for the first few minutes with nice cold air, and then quits working for the rest of the ride.
I was worried it was the compressor going out, and one shop said that would be about $900 to repair.
If it could be lack of refrigerant causing the problem, I’ll probably try to do a DIY recharge to see if that solves it before spending a minimum of $100 on repairs.
Thanks for any advice you may have!
