Default AC Help

I had a new compressor installed and my AC worked great for a month, then it stopped blowing cold.

I tried to recharge it with an over the counter can and it won't charge. Any thoughts on what is going on?

You try to recharge it, but what are the system pressures at currently?

You should get your hands on a manifold and check the pressures as suggested, it will make it easier to tell whats going on. Just shoving a can in likely won't solve the problem and if you leaked out enough freon in the last month to trigger the low pressure switch you have a real problem that needs to be solved.

Is the compressor activating when you push the a/c button? does the high speed fan kick in when you push the A/C button? does it activate the compressor if you run 12v direct to the compressor clutch? have you tried bypassing the low pressure switch and seeing if the compressor kicks in?

Is the AC compressor engaging when you activate the AC button?

You need to know that before proceeding any further.

Default AC low side adapter

I have two low side adapters that are 90 degrees. They screw onto the compressor port OK, but when I swing the compressor back up to it’s original position the adapter hits the alternator/compressor mounting ears. Did you run a longer or shorter belt to do this? Did you have to modify the mount or the mounting tubular nut rod ends??What brand adapter did you buy,and how is it oriented? I would like to get this mod behind me. Thanks in advance.
