A/C stopped working so added AcPro recharge bought from Walmart worked for couple of months then stopped again. So bought more AcPro but now system will not pull in refrigerant from new can, fan not engaging, only one fan system on radiator, clutch on compressor constantly turning, not cycling on/off, always spinning but only when A/C is on inside car. Off otherwise.
so bought gauges low=80 psi and high=98 psi when engine is off with engine running low=37psi but high=35 psi.
and I notice after 10 minutes of running fan does not come on at all. Going to have to take a look at that. Your thoughts?

So we may have two issues. The fan not coming on maybe different then the A/C issue. So let's address the A/C issue and then if that fan issue is not repaired as well then we can start a new post for that.

The pressures that you have are common for a failed compressor. When they are about equal when the compressor is on shows that it is not able to build the pressure and create the differences in PSI.

If it were me, I would replace the compressor and go from there. Here is a guide that goes through how to evac and recharge the system:

Here is a guide that codes how to replace the compressor:

I also attached the process from the manual. Let us know if you have other questions.
