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

Resolved Question:

Problem:
2007 Honda Odyssey; AC blowing warm air.
Description:
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?

MASTER TECH :

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

MASTER TECH :

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.

MASTER TECH :

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 see you came back this morning .
Did you have any more questions or have some results for me ?
Customer: replied 5 years ago.

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.
