Thanks for providing the pressure info

Should this be checked with the engine NOT running?

I am getting a P1641 AC Clutch Relay Control Circuit code and my AC compressor is not kicking in

I plan to check the power going to the compressor and the the switch on the AC line, but am wondering if maybe I have too much refrigerant, and on hot days like today, I have too much pressure in the system and it doesn't turn on because of this

Would like to check pressure using my friend's AC machine, just need to know if reading should be made with engine on or off. If engine off, should it be cold?

A/C pressure is checked with the engine running and the blower on high. An excessive charge will turn off the system as the pressures will exceed those shown in the chart above, The ranges shown there are correct.

First chart above is with the system off and hasn't been on in a while, second chart is while running.

In a totally unrelated note, the air conditioning n my apartment died today, system blows but not cold. When the apartment people refused to answer their phone, I went out side and found the capacitor blown at the condenser. Got it fixed an hour later, after the maintenance guy tried gaslighting me about not reading the thermostat properly (I think they're starting to run low on R-22 and don't want to charge their leaky 25 year old systems more than necessary).

Thanks guys... Last night I hammered the gas and pretty sure I snapped the joint inside one of my axles.. So AC will have to wait until I get this fixed. My F23 has been bullet proof, but the remaining weak link is the axles. crap..

thanks for the advice
