I have a 2017 QX60 with base radio. The radio and climate control buttons don’t work right away, they take about 30 minutes after starting and running the car for them to function.
Any ideas how’s your fix it?
There are several things that can cause electrical problems for your car's air conditioning. These can include failed switches, a blown fuse, a problem with the control module or something else. Fuses can short out and make the A/C stop working or a loose connection can create an electrical short that is easily fixed.
Agree with bracepil57, electrical problems are difficult to troubleshoot without tracking down the specific cause, and can be caused by a number of different things (sometimes unrelated). You’ll need to get someone in there to narrow it down without the cause throwing parts at it.
