ZJ A/C System Re-install

I had completely removed all of the under hood components to the A/C system on my 1995 ZJ several years back and of course didn't save any of it. Figured that if I ever wanted to put it back on I should be able to get all new parts anyways. Well now I am putting the A/C system back on and found a few parts I couldn't buy new. I think I'm down to only missing one piece though, I can buy a new sensor that screws into the accumulator/ dryer, but the one I am having trouble finding is the sensor that is in one of the lines near the compressor right in front of the intake manifold. I'm not sure if its the high or low sensor, the Chilton manual is usless for the A/C system.

Welcome to the forum.

Why not get that missing part from a junk yard?

The evaporator is a common failure point. Why not suffer like the rest of us and replace that part to attain a working system?

Maybe contact JeepAir and see if they can help?

Thanks for the welcome.

That is what I'll have to do if I can't find it new. Wanted to replace it with new if I could so that everything is new and should last a while.

I hope the evaporator is still good in mine. I'm putting it all back together now so I should have a working system. How difficult is that to get to?

Replacing the evaporator is the most difficult job to perform on the Jeep.

It would surprise the heck out of me if yours is still good.

Connect a vacuum pump to one end of the evaporator and plug the other to see if it leaks.

Don't waste your time w/ the system and a bad evaporator.

This topic shows my evaporator replacement. That topic is also applicable to your vehicle.

It's the high pressure cut-out switch. Available on RockAuto under:
Jeep:95:Grand Cherokee:5.2:Electrical-Switch & Relay:Refrigerant Pressure Switch

Several options from $8.71 to $23.79. Looks like you need to know if you have the round or oval connector.

Edit: the evaporator in my 93 is still original and doing fine.

Thanks didn't see that one down that far. I only saw the ones under the A/C clutch switch.
