My ac unit isnt turning on...i tried another and had the same results. I also checked the fuses and non seem to be blown. I swapped out the interior a while back and it might have something to do with that. I have these two connectors that im not sure of where they go.

any ideas?

 

those two look like the ones that hook up either to the back of the unit or to the connectors in the dash directly behind the A/C unit. Where did you pull those plugs from?

 

OK this is my first time trying to upload some pics so here goes. Top 3 pick are the plugs for the back of the Radio. The last one is for the back of the climate. Luckily I had this apart still.

 

hmmm i have 2 blue plugs?? i'll take more pictures today....

 

Have you checked your relays possibly??

 

That would be helpful. What year and model SC do you have?

 

There is two connectors right on top of the climate control when you put it back in. Does your climate control power on?

 

im swith stick3, the pic in your first post looks like the two plugs that are attached to the dash/blower assembly directly behind the a/c control unit/radio

 

on my car, the fuse box on the driver side, I forgot the fuse number, is the one that give me problems, is not blown but it make but contact, i usually take it out push it real tight again, on the plugs on the ac controller I forgot wich plug, the color green cables, they always have constant power, just check with a voltimeter, i will try for look for diagram or pictures.

 

its a 1992


It does not power on. Where exactly do those two connectors go?

If anyone has a picture of the female part, that would probably be the best bet.



I know the radio doesnt belong but i dont think the radio needs to be connected for the climate control to work?

Im pretty sure the issue is with those two plugs (white/blue)

 

Awesome, found a picture thanks to raines thread! Thanks for pointing me in the right direction guys!

Hopefully this will solve the issue. If not i will report back.

 

This is the back side of the OEM climate control and connectors for a 1992 Lexus SC400

 

Those are the plugs, im 100% sure of it. I just got through diag work for my SC and was working with those plugs for a/c wiring. Should get you up and running

 

yep thats the one!! thanks guys! AC is working woohoo...

now im not sure on the radio...could i just get a harness adapter and make it work? i dont think the car came with an amp? but i may be wrong...
