'99 TJ A/C Question

So I have done some reading and searching and about to buy a manual or take it somewhere but before I do I thought I would see if some on here could give me a hand.

My A/C on my new rig doesn't work and I want it to. The compressor is not engaging when I turn on the a/c. I have briefly hard wired the clutch and the clutch and compressor do function. I have bypassed the low pressure switch with a wire but still nothing. The relay is working and I have swapped the relay with another one....nothing.

Now the high pressure switch is not showing 12 volts and appears to be grounded...seems a little odd.

What else should I check?

Thanks

I wish I could help, my move was to take it to a shop and fork out $1200 for a new system
But my nipples are hard every time I turn it on now

Is the system fully charged with R134?

I would have loved to learn to do it on my own, but in this Southern humidity it was easier to let them have the Jeep for 3 hours and be done

Hey nick, the control panel commonly goes out on the tj air controls I believe. Just replaced mine (along with every other part) that might help

Sounds like you are low on 134, the compressor is wired not to kick in when low of 134, get system rechared then see what you got, don't bypass the compressor clutch again it will damage the system.
