Ae82 Air Con Problem...... It Wont Go!

hey guys and gals, ive just recently put the engine back into my 1986 fxgt and for some reason the aircon wont go ........ though it was working realy well before removing the engine.
ive noticed the pump wont spin when you press in the a/c button so i got my test light out and have so far figured that theres no power going to the pump where it connects and ive traced that wire into the cabin but then it dissapears into the loom and i cant seem to find where it goes now.

does anybody have any ideas why im getting no power to that wire or know about a/c ing? and how it works? i was thinking a relay or fuse or a switch maybe but i dont know whats what in the car as its missing all its fuse covers etc .

low gas maybe?? ( it sat idle for about a year and a half) but pump goes quite cold when you turn it by hand so theres definatley gas still in the system

im a member of the AE82 owners club and theres heaps of good info on there but not alot about air con so havent had much luck trying to get it to work.
any help would be totally appreciated. thanks :)

Get someone to check the gas pressure, also the a/c fan relay. Else you could find the pressure sensor and bridge it and push button to see if the pump will kick in to see it the gas pressure is enough.
When you push the button do the fans kick in?

at the mo the fans are going all the time as i think the water temp fan switch is poked. the a/c button lights up when pressed and ive found a relay under the dash on the passeger side that i can feel click when i press the button in so maybe thats the relay to replace? i was thinking of bridging the a/c pressure switch but i dont know what one its is. thers one screwed into one of the a/c lines coming out of the firewall but if you trace the wires, one of them goes to the water temp fan switch so im unsure if its a pressure switch or just a fan switch for the a/c. i was just thinking of hooking up 12v directly to the pump and see if maybe just running it might build up more pressure and posibly might make things go again???
