Only takes about 110F to have r134a at 150 psig vapor pressure.
But at 150, its not a low pressure that keeps it from cycling.
Temp pressure, psia
100 138.2
125 198.2
150 276.1
Prolly dont want to leave can in hot car.....
as said, jump low pres switch to engage clutche
if that dont work, you can try 12 v directly to compressor plug
if that dont work its bad clutch fo sho.

I had a small leak on my old truck. The gauge on top of the r134a bottle went bad and I ended up over charging the system and blowing a seal. Instead of replacing just one part I got to replace the whole system.
If you do decide to mess with it, even a little, get a reliable gauge setup.

ill give it another go and see what I can figure out. If with the new gauge reads an extremely high pressure like before when I use the new gauge I won’t touch it anymore and leave it be. Till then I’ll get back with you guys on what I figure out... thanks a lot for all the advice.
ps I moved out to Utah so the temps are a little hotter here. Avg 90f-95f

I just realized the can I was using the “reusable” dispenser was faulty and was not even spraying the product out which is leading me to believe that’s why the gauge was reading such high psi when I hooked it up. I’m goin try and find a different gauge to use and see what it will read. (Yes I never leave the can in truck when I’m not using it thanks for the heads up)
