I really need help in the wiring diagram of the A/C. My blower works, heat works, even when i press the a/c switch the green light turns on for the A/C, The compressor wont kick in at all. Its a 1JZ Soarer swap SC300 with Dr.Tweaks harness. I dont know where to start from or how to figure this out. Code just says Solar sensor is open. I did use the research box which tells me i will get that code if the car is in shade. But it throws this code in the light too.
HELP! I want to make the A/C work!! although the winter is coming, i just want to prepare for the warm weather already.

Thanks in advance!
Cheers

 

i have the same thing... any help would be great

 

I am assuming you too are using the stock ECU? If you have the AEM I can help. I have read many threads on this and to fix the problem you two are having is to run a relay. Let me see if I can find the thread on this. If you have the AEM, use A17 and A27 for the AC to kick on and off. That's how I have mine ran. Works great, no issues, except for the idling from time to time.

 

Running stock ECU. A17 AND A 27? are those the pin outs on AEM? I'm wondering if anyone else ran into this problem before and figured it out on stock soarer ECU

 

Yeah those are the pinouts for the AEM. Did you find the thread on the relay that several have had to use?. Try even SF(supraforums).

 

Not yet, all the threads i have come across are leading me no where. If you are able to find a link please PM me i would greatly appreciate it, meanwhile i will look for it too. I can wire up the relay, but i need to know which pins run the compressor from ECU.

 

I have a 1jz in my garage with a working a/c system, Give me sometime to pull the harness out and chase the a/c wiring down and i will tell you what to do to get it to work, i promise.
You are using a supra ECU? Or JDM ecu?

 

I still can't figure it out. Had dr.tweak make the harness originally for aristo ecu. I never ran it and put in a supra jdm 6 speed ecu. Tweak has a relay wired into the harness for the ac. The compressor will not kick on. Tweak told me to remove the relay by cutting the two wires coming from the ecu and cap them off and the other two going to the engine connect together. I did hat and still nothing. Any help oumar? Light comes on green when I push the ac bottom on climate but compressor will not come on.

 

I'll help you out give me till tomorrow morning please.

 

Thanks. I'll keep checking this thread
