Lexus GX 2012: Issues with Heating/Cooling System and Troublesome Warning Light

Hey, sounds like you're in a bit of a pickle. Had a similar ruckus with my 2009 Lexus RX a while back. That little warning light was like a squatter on my dashboard too, and my AC was more like a faint breeze on a hot day, almost non-existent. Turned out it was indeed a problem with the sensor, or more specifically, the cable or plug connection from the sensor. What happened was the plug had been dislodged somehow, probably through normal wear and tear. My mechanic had it sorted quite quickly once they did a proper check and discovered the issue, so it wasn't a hefty job. But I must say, ignoring it is not the way to go because it affected the overall performance of the car over time. The work involved was straightforward, they just needed to inspect the wiring and re-secure the plug connection. They also double-checked the sensor and the system as a whole while they were at it. Just remember to give your mechanic the heads-up as it might require a bit of hunting to track down. Good luck and hope this info helps!

Hey there, sounds like you went through quite the issue with your RX. Lucky your mechanic got it all sorted out. Do you recall how much that whole fix set you back? Also, has anything else cropped up relating to the same issue since they rectified it? Cheers!

Hey, yeah it sure was a bit of a doozy with the RX. In terms of costs, I shelled out 155€ for the repair. This was mainly to get the cable or plug connection from the sensor fixed. It wasn't exactly a bargain, but considering the hassle it saved me, it was money well spent in my opinion. And as for your second question, well, since my mechanic sorted it out, the outdoor temperature sensor has been shipshape. No issues or glitches to report there, and no repeat of that warning light squatting on my dashboard, thank God. Turns out, handing it over to the pros did the trick. Cheers!

Heyy thanks for sharing all these details and your experience. It's quite a relief to hear the solution turned out to be straightforward and not overly expensive. You're right – it's money well spent to make sure the car's in shipshape and to ward off any future complications. I'm glad to know that your sensor's holding up well with no more pesky warning light. Now, I just need to screw my courage to the sticking place and make a visit to the mechanic. Fingers crossed it all goes as smoothly as your experience. Cheers!
