So, on my last 400 mile trip with 95 degree weather, my AC was barely able to keep up even though I had to run it on max speed for fans. Considering it is 13 years old, it could use some refreshing. All of the local places are asking lots of money re recharge the system. I do see lots of kits for DIY out there as well.
Did anyone try to do any of those kits and is there any info on whether that path is even worth taking. My AC is working, it is just not as cold as it used to be, so I don't want to mess anything up
Thanks for help!

if you have the AC manifold then its easy to top off with refrigerant (and get an idea of the health of the compressor). those spray can looking things are fine but the 'possible' issue with them is that section of the hose 'might' have air when installed - I have not verified if those hoses are empty(vacuum) when sold. Ideally it should be flushed out with refrigerant

Once you see or feel refrigerant escaping, quickly tighten the connection to stop the refrigerant flow. Open the valve on the refrigerant can to start the flow into the A/C system. Start the vehicle and turn on the MAX A/C setting. This helps draw the refrigerant into the system. Shake the can occasionally as the refrigerant is being dispensed, you'll feel the can get cold. Some charging hoses come with gauges you can monitor but many just raw dog. A thermometer in the vents will help gauge cabin temp. I'm sure the FSM has all the HVAC particulars.

With the can of refrigerant upright, slightly loosen the hose connection at the can until you hear a hissing sound. This will allow the refrigerant to push out any air trapped in the hose.

I just replaced my compressor with a reman and I was surprised to see that this is the most efficient AC compressor I've ever deal with. the gauges show 25psi on the low side is 250psi on the high side

I'm swapping out the heavy OEM fan for a SPAL slim fan and just wondering what others did for wiring. Obviously tried searching but it left me less than enthused with the results.
2 options I'm considering,
1) Snip the 2-wire plug on OEM fan and run to SPAL, mount the control module somewhere near but not directly in the flow of the fan (space). I'm only concerned since this is mounted in direct fan flow from the factory, does it get appreciably hot?
2) Buy a solid-state relay to PWM the fan. Heat is still a thing but a single fan probably isnt going to pull too much power relative to their capacity.
Im leaning towards option 1 since only a single fan but would hate to have it fail on me cause it overheated.
