Hello,
I've watched some UTUBE videos, but no experience recharging A/C on any car.
The sticker indicates to use R-134a Part #12345922 or equivalent 2LBS, 0 OZS
AND
Synthetic Oil Part #12345923 or A/C system will be damaged.

Can I use "AC PRO Refrigerant" and does it already include the required Synthetic Oil?

Any special tools required?

Thank you very much.

Always add to the low side. Also you do not want to overfill the system. So you should get the gauge to determine if the system is low.

But with that said are you getting any cold air at all?  AC Pro is not going to solve a major leak only minor ones.

If you are getting some cold air a top off may work for a while and possibly seal a small leak.

But if no cold air at all this would most likely be a temporary fix.

If this car is a keeper you may want to just bite bullet and get someone who knows what they are doing or you will cause more damage. The good thing is you are running R134a and there are many places that can fix your system and find the leak.

System was getting warmer and then A/C OFF, "refrigerant low" diagnostic message popped up.
A/C will not go back on.
Thanks,

In a modern system it's not normal to have to add freon.
You have a leak. It should be worked on by a mechanic.
You don't have to add oil right now. If you want to give it a little shot of 134 it will get you working again but not for too long.

I would say Brian's correct on this one. Sounds like a leak that AC Pro is not going to fix or at least not fix for very long. If system is off you are low enough to kick in the low pressure sensor and have turned off the compressor.

You could give it a shot but if in 2-3 weeks its back to not working, then a repair would be needed. I suspect this will be the case.

It's also possible that the power to the compressor needs to be turned back on through programming of the ECU. In other words simply adding freon may not restore the function.
The other problem is you can over charge it and create another problem.

How do you turn on the compressor in order to recharge?
Thank you,
Matt

Jumper wire across the terminals in the plug of the low pressure cutoff switch usually works fine.
