1995 chevy astro any techs online??

Van has some electrical gremlins. ac not working from inside vehicle if i jump 12v to blower motor it works, if i jump 12v to the compressor the clutch engauges and it works. I want to byp the vehicle side of the ac system. My intent is to install two switches one to the blower and another to the compressor with inline fuses for protection. I plan on somehow incorperating the low pressure switch but dont want do damage anything. Unfortunately i DONT have the money to take it to the shop all i want is some ac for my kids it gets just a little hot here in southwest florida lol. PLEASE HELP ME AND MY FAMILY! Thanks sooooooo much
