Does a 2002 jeep grand cherokee have a low pressure ac switch


Yes.
It should be one of the ports on the compressor or the lines to the condenser. The low side port is smaller than the high side.

How do i find low pressure ac side


The low pressure side is between the evaporator core (in the dash) and the compressor. It is the big tube. This is the side that you charge when servicing the system.

1999 Jeep Grand Cherokee. AC problem. Fan and inside controls have power but compressor clutch not engaging. I am thinking that there may be a relay that is out. Any suggestions for troubleshooting...


The compressor clutch won't engage unless there is freon in the system. Connecting a gauge to the low pressure port should tell you if there is. Pressure in a system that isn't running varies with the outside temperature.

Where is the low pressure ac valave on my 99 Jeep Grand Cherokee?


Jeep Grand Cherokee SUVs manufactured in or before 1995 use R12 refrigerant. You mustretrofit these SUVs to accept R134 refrigerant using a retrofit kitavailable at your local auto parts store before you can recharge thesystem. In some areas, a license is required to retrofit an airconditioning system. If this is the case in your area, take your Jeepto a professional to retrofit the system.

Locate the Low Pressure Side connector port: You will find it on the driver's side of the engine.

A/C kicking in and out.


There are 2 lines coming off the AC compressor, one is larger than the other (that is the low press line), the low pressure line is the common place that the switch is located, the other is the accumulator can, the low pressure goes to the accumulator, in any event it is always in the low pressure side, large cold line.
