The aux fan isn't needed to blow cold AC unless you aren't moving. You def need to get some pressure numbers if the AC blows hot air initially. Need a little more info like does the blower blow right away just hot?

When compressor kicks in cold is nearly immediate. If it's hit and miss that's usually a problem with a variable compressor. Get readings when it is working and when it's not to confirm.
