Hi all,
My A/C compressor is not staying on. I press the A/C button and I hear it click like it's engaging but it cuts on for a few seconds then the A/C button blinks.
I installed a new A/C relay, condenser, evaporator, and compressor. I took it to a shop to have it changed and its holding pressure.
I'm not sure what to try. Any thoughts by the group?
Thanks
the AC exciter (or whatever its called) is behind the glovebox. it might have become disconnected. when i rebuild my engine i forgot to plug this in and mine behaved the same way

>On the passenger side, get on the floor and look up under the dash behind the glovebox. You'll see the blower motor and some connections around it, make sure everything is connected up there. Mine was doing the same thing when I first bought the car and the AC amplifier connector was disconnected which caused the button to blink.
Hard angle to get a picture from but here's the best I could take:
ok will try mine. yeah i got mine with the a/c blinking.
they say its the compressor but ill check ont his this 1st.

There is a switch on the compressor, you might want to check that as well.
ok some things to check to help me help you:
does ur ac compressor actually kick on?
do the fans turn on at low speed when they do?
does it stay on for a couple seconds, click off, and then blink the light?
check the wire going to ur compressor, how many are there? (one pin, 3/4 pins)

i work for a toyota delership and most of the time when the light flashes the car is out of freon i know it sounds stupid. but check it there is a site glass on the dyer it is located behind the drivers side high beam follow the lines make sure the car is running and watch for bubbles if they apear it is low. if thats not it replace the magnetic clutch relay in the fuse box with one from the junk yard like 5 dollars and see what happens. also if it is out check the condensor for oil spots.

You either have the incorrect freon pressure, or your swap wiring harness is not wired up correctly for AC.

when i first got my celica mine did the same thing... light would blink after the ac was on for a minute or so. it ended up being something really simple... ac belt was slipping never heard any squealing or anything but after i changed the belt i havent had an ac problem since. by the way i found out belt was slipping by the battery light eventually coming on a few days later, i was actually still scratching my head on the ac problem, but after changing the belt the ac light stopped blinking and has worked well since.
I have the same problem with my car. After the swap the a/c light started blinking. I know its not the freon because I never disconnected any of the lines and the a/c compressor was always working before the swap....
EDIT: I checked that plug from the picture and there isn't anything connected to it so I guess I found my problem... Sorry for jacking the thread as well lol

Got the same problem, but the wires seem to be cut,
Where am I suppose to connect these to?

Another thing that will cause the light to flash is when the compressor gets wet, like from a puddle, and the belt slips momentarily. I've had that happen a couple times and just shut it off then on again and it was fine.

In my case the wires aren't going anywhere, not sure if it shows properly in the pics.

How did those get cut?! The herbed should be laying underneath your glove box somewhere. That part of the wiring harness are part of the engine harness that comes through the firewall behind the glove box. They should be there somewhere.

I got the car like that. Ac never worked didnt realize until it started getting too hot here. Usually I kept my windows down.
Ill take he glovebox out and look around. Get better pics.
If not would anybody have a wiring diagram or can someone take pics of that area if they have the dash apart?thanks in future

Opened the glove box. Looks like those two wire sets are supposed to be connected but where does the other part of the harness go?
I looked to see if the wires from under the hood are coming inside and they seem to do...any advice?
I'm basically trying to figure out where the wire in red go?

older toyotas had the problem when it rains heavy and you just have to repress the button.
another thing to look at is your a/c clutch.

Ill search about the clutch but I still have to connect the wires...
I think it's the one that comes from the engine bay harness but the problem is that the person who did the swap didn't use the factory place (passenger side firewall) area to bring them in.
Anyone have the wiring diagram of the ac? I looked at my other celica it's the part that connect to the switch that is cut in the picture and that switch/harness has 3 wires going back the the engine
I need the diagram to see where those wires go so I just rewire it

Anyone have any advice?
I was thinking if someone can tell where the wires go I rewire it all new directly from that harness to wherever they go in the engine bay
I really need ac in the Texas heat so any help appreciated
