So I’ve got a 95 Chevrolet c1500 pickup. I just put a new engine in it like two months ago. I have been trying to get the ac working since it’s over 100 degrees where I live. I bypassed the pressure clutch switch with paper clip and the clutch kicked on. So I got get a new switch thinking that will fix it with a can of Freon. Only used one can. While I was putting the Freon in the clutch started turning but it didn’t stay turning. It would cut on and off repeatedly. So I go pull the ac relay fuse out from under the hood and thinking I might have a bad relay. I did the paper clip thing again but I didn’t turn off the truck so it made a small spark and the clutch stopped turning all together. So I went in the truck and turned the fan and ac off. I found out that since the spark when I turn the fan on it automatically turns the ac off. And the there isn’t hardly any air flow coming out of vents but you can hear the fan cut on. If the fan is off the ac is on and the clutch is short cycling but will not stay on when I turn the fan on. I need helppppp. Did I short out the blower motor relay or what?

New and hope this is the right place to post this question.. Got a one owner clean 95 Chevy truck 5.7 and it an A/C nightmare.............. Worked fine all last year after i put a low pressure switch on. Then started working only a cold start till you shut it off. Restart it w/ warm motor, blows hot. Let it set a few hours blows cold at cold start again. Till you shut it off. Then quit all together. Tried to jump the comp. over at the comp. (not at the accumulator). It wouldnt turn on. Due to low freon sensor in comp. Put 1st can of 134a in comp. turned on instantly. Added 2nd can. Blew cold for 10 min then hot .Without shutting the engine off. Wouldnt work at all. Thought all freon leaked out. Put a can of UV Dye/134a in, comp.came on blew cold for 10 min. wouldnt take but half the can of dye. Got out black light. NO LEAKS! Comp. wont kick on. Thought it was too full, Let a small amount of freon out of the hi pressure side. And started it w/ cold motor, it cooled for hours, till i shut it off. And back to the same thing. Let it set for a few hrs. And blows cold till you shut it off. Restart it w/ warm motor blows hot????? WHAT THE HELL!??
