Ask Your Own Honda Question
Customer reply replied 2 years ago
Yes, I filled myself
Mechanic for Honda: Tim Mohr, ASE Master Tech replied 2 years ago
what were the high and low side pressures? After you filled it? how much did you put in?
Ask Your Own Honda Question
Customer reply replied 2 years ago
I didn't check the high side. The low side started at 25 and i filled to 55
Mechanic for Honda: Tim Mohr, ASE Master Tech replied 2 years ago
55 is too high, it should be 35 when idling and the a/c on, you need to drain the freon and put the exact amount in it, how much did you put in it?

Customer reply replied 2 years ago
i put in about 6-8 oz
Mechanic for Honda: Tim Mohr, ASE Master Tech replied 2 years ago
the problem with filling these with the do it yourself kits, is you have no way of knowing how much is in the system all ready, it is obviously over full now, so you will need to evacuate the system, and put the correct amount in, in this vehicle, it hold 17 ounces, no more, no less, Tim

I evacuated the system and added about 8 oz. The fan starts when I turn the ac on. But, I don't think the clutch engages. Also, when I hit max ac, the ac doesn't bo more air
Mechanic for Honda: Tim Mohr, ASE Master Tech replied 2 years ago
when did you evacuate it, today??? can you start from the beginning including why you charged it to begin with?

My daughter's car (not the one in question) had an o ring leak. I fixed hers and added freon to the CRV. It worked fine for about an hour. Then, it was blowing hot air. So today, i pushed in the valve to let all the pressure out. Added about 8 oz of freon. Now the fan starts when I turn the ac on. But, I don't think the clutch is engaging. Didn't hear a loud sound when the ac stopped working.

ok, we need to see if you have power at the compressor, when the a/c is on, do you have a test light or a volt meter?
Ask Your Own Honda Question
Customer reply replied 2 years ago
yes
Mechanic for Honda: Tim Mohr, ASE Master Tech replied 2 years ago
ok, can you see if there is power at the compressor when the a/c is on?
Ask Your Own Honda Question
Customer reply replied 2 years ago

Mechanic for Honda: Tim Mohr, ASE Master Tech replied 2 years ago
with the voltmeter, probe the wire at the compressor, and turn the a/c on, and see if it has 12 volts,Tim

Your answers were clear and the diagrams were perfect. Dealer wanted $87 for an hour of labor and even I did it in 15 minutes.

EdUSA

HONDA PLATINUM was great. I really appreciate his help. I was ready to trade my new Honda until he told me to wait until I got 3,000 miles on it and my gas mileage would get much better.

SummerUSA

I took the Power Steering O-Ring service bulletin linked from JustAnswer to my Acura dealer, and not only did they no-charge the o-ring, they also replaced the power steering pump at no cost.

Gary RStevenson Ranch, CA
