Good Info twomr2's

Yep have bridged out all sensors already as whoever did the timing belt previously had taken out the ac compressor but fans were still running

Terminal 10 on the ac amplifier having 12v instead of an earth is about the only thing I can see an issue with

if it helps anyone else,i just added the system outline to my last post.
 
just to confirm with the OP the year of the car and also;
 
-you have run a wire from one side to the other on the h/p switch Plug(like cruiser said,and in the link you posted) and still nothing/wont turn off?
 
-you have no A/C compressor fitted/gassed
 
-have you checked the A/C amp?-pull it out of the little black box and see if its melted on the circuit board anywhere
 
-all relays are working correctly
 
cheers

Why do people say "grow some balls"? Balls are weak and sensitive if you really wanna get tough, grow a vagina! Those things take a pounding!

A/C amp is behind the glovebox,mounted to the evap unit.
note the 93 model amps are different to 90/91 model,and ive read that toyota made a mistake when printing the 93 bgb for the A/C amp,they just copied the 91 bgb and didnt change the wire allocations for the changes made (for 93)
 
 pressure switch is on the rhs of the front trunk,(black one with two wire plug coming off it)
