Honda Odyssey EX-L: Problem: 2007 Honda Odyssey; AC blowing

Resolved Question:

2007 Honda Odyssey; AC blowing warm air.
Air will blow cold for at startup then stop; Compressor will start and stop a few seconds later after car has been running.
What was tried:
Tried to add freon; only to get a aprox 95psi high reading
Van was turned off and re started to get a 30-35 psi low reading; it took aprox 18oz of freon; low reading to 80 psi, but the compressor kicked in and out through the process.
Van continued to operate to the description above even after adding the freon.
Can a parts store (Auto Zone) get any reading form a plug in analyzer? What is your suggestion?

Hello welcome to just answer I'm Master Tech and will be able to assist you today.


ok first of all the system is WAY over charged,the first step is to have this evacuated and then correctly charged with a professional a/c machine then continue the diagnoses.


now before you added the freon was this a virgin freon or the stuff they sell over the counter and has oil and sealer in it ?

I did not see your answer until now because is had to leave for a trip... I bought a $10 relay and replace the main; no cold air; I then took the relay that was removed from the main relay and swaped it with the compressor relay; no cold air. I also called a friend and he said the freon pressure seemed high. Just as you said. I have to get it corrected.
