A/C Compressor Clutch Wont Engage

What should I check next?

I Fixed the clutch gap at the compressor. measures at .022".

But the clutch doesnt engage. No voltage at the clutch switch or the high pressure switch.

If I jump the low pressure switch, the clutch comes on. OK.. Bad LPS. Installed a new LPS, and the clutch still only comes on with a jumper on the LPS side.

What do I check now to get my A/C Working again?

Correct. Put some in until the compressor kicks on.

You can get the can that has a gauge on it. Check it and if it needs some put some in, if it needs some check for a leak

Freon is a fluorescent green if the leak is big enough it will be obvious so look look for that color. Most parts stores sell a light to aid in finding a leak, worst case scenario you take it to a shop to have them find it
