If the compressor is working, the system is completely clean, and there are no clogges or leaks, then why wouldn't 134 go in.

This is my final problem for my A/C. I'm counting on you guys to save the day once again.

You have to have the vehicle running with the AC running on high and put the refill into the low pressure side IIRC. Only thing I can think of otherwise is, is the hose or whatever you are using working right?

Lifelongtoy

It might be the hose, didn't think about that. But ya, got the A/C is on high on the low side.

I was thinking that it might be something with the pressure switch. Maybe somehow it is not functioning

is it an old can? i had the same problem, went and bought a new can and presto

Intrepid

I don't know what you are using, but did you puncture the top on the recharge can?

Sometimes it takes a couple minutes for those cans to empty themselves. Hold it upside down, and every 5 seconds turn it on its side then back.

did you remove the old valve core before you put the 134 adaptor on? and are you sure you are putting it in the low side?

Lifelongtoy

THAT OLD CORE HAS TO COME OUT!!!! Ohhh man. So if the core is still in after screwing the new adapter on, nothing will go in?

but yea its on the low side.

turn it upside down or put the can in warm water. also you can feel the can gets light when its empty.

i hope thats sarcasm. but if not, yes you must remove the old cores before the adpater is screwed on
