Lexus GX 2004-09 :: Check Connection Of Air Conditioner Message But Everything Works On GX470

I recently purchased a used 2004 GX470.

Everything on the Info/Nav Center screen seems to work, at least as far as I know so far, except when I push the "Climate" button, I get the blank screen with the exception of the "Check the connection of the air conditioner" message.

When I got it, the A/C wasn't working, but it was trying. Today I added gas to the system (it was a bit low) and cleaned the cabin air filter (disgustingly dirty, with next to no air movement through it). Now A/C is there! (it is 100+ today!)

To get around the missing climate control screen (and what I assume are controls thereon) I turn on the recirculation button and also the "auto" button, and raise or lower the temperature controls. Heat works when I turn the temp up, A/C tries when I turn it down. But I still get the message on the control screen.

I assume that the control screen for "climate" also includes some widgets for controlling and/or setting options, such as (hopefully) just running the fan without A/C with external air (should I so desire on a cooler day) and stuff like that.

I have seen others fix the similar problems by reconnecting some clips behind the screen, which I can certainly try out, but seems like the other similar problems, when the issue was a wire loom connector behind the screen, that they had other problems, such as the A/C not working.

I THINK all my systems are working, I just can't see the climate control screen. All the other systems (audio, settings, maps (different subject later *L*), etc. all work and seem to display OK, so I don't think it's the screen.

Lexus GX 2004-09 :: Check Air Conditioner Warning Message Flashing

I have a 2003 GX470 with 174,000 miles. It continues to be a great vehicle.

Recently my air conditioning system only blows warm air in both the front and rear. When I start the vehicle, the Navigation screen flashes the message "Check Air Conditioner", then the A/C button on the Climate screen flashes.

I have searched the forums and read every post regarding this issue, and it seems that one possible fix is the "magnetic clutch relay", but the link to Sewel Lexus lists this part as belonging to the ES330, and NOT the GX470. There is NO such part listed for the GX470 on that website.

One other post suggested that the author pull the AC error codes, but I don't know how to do that on the GX470.

Lexus ES 2007-12 :: AC Button Light Blinks Occasionally / Check Air Conditioner Message

I had a new compressor installed on '07 ES350 and now every now and then the AC button light blinks, the cool air shuts down and I get a message on the screen saying "Check Air Conditioner".

It only occurs occasionally --maybe not at all one day and two or three times another day. I returned to the shop that installed the compressor and they don't seem to know what is causing the problem. (They said maybe a freon overfill and adjusted that --but it's still occurring.)

Passat (B5) :: 2002 / 1.8T - Small Leak In Transmission Cooler Line At Radiator Connection

Had a small leak on show up in my transmission cooler line at the radiator connection. After replacing the o-ring, which was pinched, I had lost some fluid up to about 3-4 oz. I had stopped by the local VW dealer and picked up a liter of ATF fluid and noticed the colors of the fluid differed from what drained out from the cooler line. Fluid that drained out was a cloudy darker green/grey and the new ATF fluid had a clear yellowish tint. Is this vehicle equipped with a closed loop cooling system or does it use the actual ATF fluid as the cooling medium?

Ford - Explorer :: 1998 - Fuel Vapor Line Connection Broken At Tank?

1998 Explorer. The fuel pump went out so today I dropped the tank to replace it. I got the 2 fuel lines off and the 2 electrical connections off with no problems but when I went to try and take the vapor line off, the tabs on the connector were brittle and broke. Now I am stuck not being able to put everything back together since that line wont lock on. I was wondering if anything I can do.

I have tried looking online to no avail except for one site selling ford part that has this line for almost 300 dollars. It is just a plastic line that leads to a metal line. Even the Ford Parts site doesn't carry it! That's insane! I was thinking of cutting the plastic line off where it meets the metal line and using rubber fuel line with hose clamps on the line and the plastic fitting on the tank. I just dont know if this will be good enough.

Ford F-150 - 1997-2003 :: 2002 - Air Conditioner Works Sometimes

So my a/c works some times. I'll get in it in the morning, turn the a/c on. It works great, ice cold blowing hard. Then I'll turn the fan down from high and in a minute or so the cold air stops and it blows warm. Then for the rest of the day it wont blow cold air(i get in and out of my truck a dozen or so times through out the day turning the truck off each time). my dad has a freon pressure gauge. We checked it and it had good pressure. the blue gauge was at 50 and the red was a hundred and some i forget, but dad said "that's where it should be" so i guess that's not the problem. I am wondering if there is switch bad or a sensor. Its an '02 fx4 f150 4x4 140,000

Airconditioning :: 2008 Pontiac GT - AC Only Works When Coolant Shows Reading

I have a 2008 Pontiac GT, regularly maintained and all runs fine. Just one problem that has popped up over the last few weeks since the warmer weather has arrived: On the computer readout in the dash, if the "Coolant" display shows a temperature (say, 83C or what have you), then the AC works. However, much of the time the Coolant reading shows "---" (3 blank dashes), and the AC does not work. It's still been quite cool around here (Toronto area) so I haven't needed the AC much but it's heating up and I'd sure love to take care of this if possible.

Ford Excursion :: Overhead Temp Shows -40 / AC Display Works Fine

I just picked up an 05 6.0 Limited and love it, but I can't figure out the overhead temperature gauge. It shows -40 degrees no matter what, but if I hit the outside temp button on the climate control, it shows the (mostly) correct temp. I verified that the temp sensor in front of the radiator is still there and hooked up, and it seems to me that Ford wouldn't go to the expense of using separate sensors for each readout, so I'm guessing that the problem is in the overhead unit itself. All of the other functions (compass, mileage, range) work just fine. I've seen several threads about the overhead dying completely as chips rattle loose. Is it also common for just specific functions to go out as things start to shake apart?
