ok. so i went from my 1jz.. to a 2jz... everything is working perfect except now when i hit my AC button. the Idle rises.... but the compressor comes on.. ive checked every fuse i could think of. i bypassed the pressure switch.. when i connect a wire directly from the clutch wire to the battery it kicks on and blows nice and cold.. but hooked up normally i cant get it to come on at all.. any ideas???? btw it worked fine with my 1jz...

Wtf engine and all things related to the engine..... forum? moved

Haven't messed with the AC much on my car, but seems you need to find the source of the relay trigger and make the corrections needed for it to kick the relay.

i spent an entire afternoon going over wiring diagrams.. and checking stuff.. either im missing something or i have a messed up wiring harness. but correct me if im wrong. the ac clutch wire goes in to the body harness by the fuse box right?

The car likes the 1j better ....jus kidding. You are correct. the trigger wire is on the bodyplugs. What harness are you using? Did you do the wiring yourself?

ippyness

its my 2jz wiring harness.. everything should work just fine.. lol i just dont understand.. i switched out the relays.. and everything. nada. is there something that if its not hooked up the ac wont work??

ippyness

ugh yeah and the stupidest thing is that the AC button still kicks the idle up!!? wtf. just doesnt turn the pump on. freakin a

When the compressor is low on gas it will not turn on. Did you check the pressure in the system.

ippyness

yea i even bypassed the pressure switch. nothing. thats how you fill the system by by passing that switch. but nope nothing. im stumped..
