A/C help

I'm on the road and my AC just died.
I don't hear the compressor cycling.
Fuse and relay are good.
Low pressure reads 150, in the red on cheap gauge.
Any ideas?

Any recent AC work done?

Check the voltage to the compressor clutch to see if there is 12V.
Could be as simple as the Low pressure or High pressure switch has gone bad.
Remove the connector and jumper one at a time to determine IF either are bad.

It looks like my low pressure switch is bad.
Is the low and high the same (same part number)?
Rockauto doesn't list separate ones.

The Four Seasons 20922 is the low pressure switch. Low off @27/Low on @41

Thanks; I ordered a Mopar one.
Part number 5096126AB

I was also seeing part number 4897613AB?

According to Mopar that part fits the 98-01 Grand Cherokee with a 4.0L and 4.7L.
