Does the AC compressor kick on and off rather frequently?
Have you connected that hose with the kit to the low side pressure port yet?
There are 2 ac ports, the low and the high side. the hose from the kit will only attach to the low side because the sizes are different. Do you know where the low pressure port is?
Connect the hose to it and start it up and hold the RPM at high idle for a bit and tell me what the pressure stabilizes at.
I thought you had already bought the AC pro kit??No?
The R134a is the correct one to use. Attach the hose from the kit to the low port, start the engine turn the ac on max then after a few seconds the gauge is supposed to drop to the correct level on the chart. somewhere around 35-40 psi. if its higher, add some charge to it until it goes to the proper pressure.
I strive for a 5 star positive rating. It's the only way i get credit. You can still ask me questions for free after the rating.
The AC pro kit comes with the R134a..
If you run into any problems you can check this video first.

Usually it only shows that high when the compressor clutch is NOT engaged. Are you SURE the clutch is engaged, not just the pulley spinning, but the center part... thats the clutch.
Watch that video if you get a chance and you can see what it looks like when its engaged.
Are you for sure the clutch is engaged?
Just by looking at the FRONT of the compressor. When its not engaged the center is not turning and when it is engaged, the center of the compressor is turning.
It sounds like a bad compressor but you need a set of gauges so you can read the high side pressure and low at the same time.
You can get a compressor for around $200 and labor is about the same.
Sorry bud, but we sure gave it a good try!
Afraid not. Getting a high and low pressure reading at the same time is the only way.....
Before you go buying a compressor you NEED to have a shop diagnose it for you. It HAS to be done with a set of gauges, NO other way to do it. Sure there can be other causes but, again, you need those pressure readings.
A tech can diagnose it in less than 1 hour.
it takes 1.3 hours labor to replace compressor
